* jit-compile and precompile models where possible (non-autosized, non-patched Keras models) - * Fix bugs and homogenize internal labels related to differing labels for early layout and different stages of full layout detection - * Replace `Lambda` layers with `ZeroPadding2D`, improving size and optimizability of models for `eynollah layout` -* Improved training - * Use connected components for loss function - * Integrate with Tensorboard to observe model training progress, including plots and visualizing intermediate evaluation results -* Simplified model usage - * Models can be overridden individually, so any model trained with `eynollah-training` can replace any model in the [distributions on zenodo](https://zenodo.org/records/17727267) - * `--model` is a CLI option of the `eynollah` root CLI now and should point to the same directory for all subcommands -* Improved reading order detection heuristics -* Improved drop capital, marginalia and column detection -* Fixing bugs in polygon handling and image operations - * No more self-intersecting polygons - * Correct rotation implementation, enlarging/shrinking canvas as necessary - * Use actual area of a polygon instead of length of polygon path or first candidate for comparisons -* Improved PAGE-XML serialization -

* deduplication, idiomatic python, clean parallel processing, class reuse, consistent and meaningful naming - - -**NOTE** We are aware of a possible issue with regards to the cropping of images. It appears that we have not consistenly cropped images for training. This can lead to suboptimal results for cropped images. If you experience quality issues with the `eynollah layout`, try setting the `-ipe/--ignore_page_extraction` option to skip the builtin cropping.

This is done by a binary pixel-wise-segmentation model trained on a dataset of 2,000 documents where about 1,200 of them come from the [dhSegment](https://github.com/dhlab-epfl/dhSegment/) project (you can download the dataset from [here](https://github.com/dhlab-epfl/dhSegment/releases/download/v0.2/pages.zip)) and the remainder having been annotated in SBB. For border detection, the model needs to be fed with the whole image at once rather than separated in patches. + +## Layout detection +As a next step, text regions need to be identified by means of layout detection. Again a pixel-wise segmentation model was trained on 131 labeled images from the SBB digital collections, including some data augmentation. Since the target of this tool are historical documents, we consider as main region types text regions, separators, images, tables and background - each with their own subclasses, e.g. in the case of text regions, subclasses like header/heading, drop capital, main body text etc. While it would be desirable to detect and classify each of these classes in a granular way, there are also limitations due to having a suitably large and balanced training set. Accordingly, the current version of this tool is focussed on the main region types background, text region, image and separator. + +## Textline detection +In a subsequent step, binary pixel-wise segmentation is used again to classify pixels in a document that constitute textlines. For textline segmentation, a model was initially trained on documents with only one column/block of text and some augmentation with regard to scaling. By fine-tuning the parameters also for multi-column documents, additional training data was produced that resulted in a much more robust textline detection model. + +## Image enhancement +This is an image to image model which input was low quality of an image and label was actually the original image. For this one we did not have any GT, so we decreased the quality of documents in SBB and then feed them into model. + +## Scale classification +This is simply an image classifier which classifies images based on their scales or better to say based on their number of columns. + +## Heuristic methods +Some heuristic methods are also employed to further improve the model predictions: +* After border detection, the largest contour is determined by a bounding box, and the image cropped to these coordinates. +* For text region detection, the image is scaled up to make it easier for the model to detect background space between text regions. +* A minimum area is defined for text regions in relation to the overall image dimensions, so that very small regions that are noise can be filtered out. +* Deskewing is applied on the text region level (due to regions having different degrees of skew) in order to improve the textline segmentation result. +* After deskewing, a calculation of the pixel distribution on the X-axis allows the separation of textlines (foreground) and background pixels. +* Finally, using the derived coordinates, bounding boxes are determined for each textline. ## Installation -Python `3.8-3.11` with Tensorflow `<2.13` on Linux are currently supported. -For (limited) GPU support the CUDA toolkit needs to be installed. -A working config is CUDA `11.8` with cuDNN `8.6`. +`pip install .` or -You can either install from PyPI +`pip install . -e` for editable installation -``` -pip install eynollah -``` +Alternatively, you can also use `make` with these targets: -or clone the repository, enter it and install (editable) with +`make install` or -``` -git clone git@github.com:qurator-spk/eynollah.git -cd eynollah; pip install -e . -``` +`make install-dev` for editable installation -Alternatively, you can run `make install` or `make install-dev` for editable installation. +### Models -To also install the dependencies for the OCR engines: +In order to run this tool you also need trained models.

[layout analysis (segmentation)](#layout-analysis), -2. [binarization](#binarization), -3. [image enhancement](#image-enhancement), -4. [text recognition (OCR)](#ocr), and -5. [reading order detection](#reading-order-detection). - -Some example outputs can be found in [`examples.md`](https://github.com/qurator-spk/eynollah/tree/main/docs/examples.md). - -### Layout Analysis - -The layout analysis module is responsible for detecting layout elements, identifying text lines, and determining reading -order using heuristic methods or a [pretrained model](https://github.com/qurator-spk/eynollah#machine-based-reading-order). - -The command-line interface for layout analysis can be called like this: +The basic command-line interface can be called like this: ```sh -eynollah layout \ - -i | -di \ - -o \ - -m \ - [OPTIONS] +eynollah \ +-i \ +-o \ +-m \ +-fl \ +-ae \ +-as \ +-cl \ +-si ``` -The following options can be used to further configure the processing: +The tool does accept and works better on original images (RGB format) than binarized images. -| option | description | -|-------------------|:--------------------------------------------------------------------------------------------| -| `-fl` | full layout analysis including all steps and segmentation classes (recommended) | -| `-tab` | apply table detection | -| `-ae` | apply enhancement (the resulting image is saved to the output directory) | -| `-as` | apply scaling | -| `-cl` | apply contour detection for curved text lines instead of bounding boxes | -| `-ib` | apply binarization (the resulting image is saved to the output directory) | -| `-ep` | enable plotting (MUST always be used with `-sl`, `-sd`, `-sa`, `-si` or `-ae`) | -| `-ho` | ignore headers for reading order dectection | -| `-si ` | save image regions detected to this directory | -| `-sd ` | save deskewed image to this directory | -| `-sl ` | save layout prediction as plot to this directory | -| `-sp ` | save cropped page image to this directory | -| `-sa ` | save all (plot, enhanced/binary image, layout) to this directory | -| `-thart` | threshold of artifical class in the case of textline detection.

Based on the document characteristics and parameters specified, different scenarios can be applied. -The binarization module performs document image binarization using pretrained pixelwise segmentation models. +* If none of the parameters is set to `true`, the tool will perform a layout detection of main regions (background, text, images, separators and marginals). An advantage of this tool is that it tries to extract main text regions separately as much as possible. -The command-line interface for binarization can be called like this: +* If you set `-ae` (**a**llow image **e**nhancement) parameter to `true`, the tool will first check the ppi (pixel-per-inch) of the image and when it is less than 300, the tool will resize it and only then image enhancement will occur. Image enhancement can also take place without this option, but by setting this option to `true`, the layout xml data (e.g. coordinates) will be based on the resized and enhanced image instead of the original image. -```sh -eynollah binarization \ - -i | -di \ - -o \ - -m -``` +* For some documents, while the quality is good, their scale is very large, and the performance of tool decreases. In such cases you can set `-as` (**a**llow **s**caling) to `true`. With this option enabled, the tool will try to rescale the image and only then the layout detection process will begin. -### Image Enhancement -TODO +* If you care about drop capitals (initials) and headings, you can set `-fl` (**f**ull **l**ayout) to `true`. With this setting, the tool can currently distinguish 7 document layout classes/elements. -### OCR +* In cases where the document includes curved headers or curved lines, rectangular bounding boxes for textlines will not be a great option. In such cases it is strongly recommended setting the flag `-cl` (**c**urved **l**ines) to `true` to find contours of curved lines instead of rectangular bounding boxes. Be advised that enabling this option increases the processing time of the tool. -The OCR module performs text recognition using either a CNN-RNN model or a Transformer model. +* To crop and save image regions inside the document, set the parameter `-si` (**s**ave **i**mages) to true and provide a directory path to store the extracted images. -The command-line interface for OCR can be called like this: - -```sh -eynollah ocr \ - -i | -di \ - -dx \ - -o \ - -m | --model_name -``` - -The following options can be used to further configure the ocr processing: - -| option | description | -|-------------------|:-------------------------------------------------------------------------------------------| -| `-dib` | directory of binarized images (file type must be '.png'), prediction with both RGB and bin | -| `-doit` | directory for output images rendered with the predicted text | -| `--model_name` | file path to use specific model for OCR | -| `-trocr` | use transformer ocr model (otherwise cnn_rnn model is used) | -| `-etit` | export textline images and text in xml to output dir (OCR training data) | -| `-nmtc` | cropped textline images will not be masked with textline contour | -| `-bs` | ocr inference batch size. Default batch size is 2 for trocr and 8 for cnn_rnn models | -| `-ds_pref` | add an abbrevation of dataset name to generated training data | -| `-min_conf` | minimum OCR confidence value. OCR with textline conf lower than this will be ignored | - - -### Reading Order Detection -Reading order detection can be performed either as part of layout analysis based on image input, or, currently under -development, based on pre-existing layout analysis data in PAGE-XML format as input. - -The reading order detection module employs a pretrained model to identify the reading order from layouts represented in PAGE-XML files. - -The command-line interface for machine based reading order can be called like this: - -```sh -eynollah machine-based-reading-order \ - -i | -di \ - -xml | -dx \ - -m \ - -o -``` - -## Use as OCR-D processor - -See [`ocrd.md`](https://github.com/qurator-spk/eynollah/tree/main/docs/ocrd.md). - -## How to cite - -```bibtex -@inproceedings{hip23rezanezhad, - title = {Document Layout Analysis with Deep Learning and Heuristics}, - author = {Rezanezhad, Vahid and Baierer, Konstantin and Gerber, Mike and Labusch, Kai and Neudecker, Clemens}, - booktitle = {Proceedings of the 7th International Workshop on Historical Document Imaging and Processing {HIP} 2023, - San José, CA, USA, August 25-26, 2023}, - publisher = {Association for Computing Machinery}, - address = {New York, NY, USA}, - year = {2023}, - pages = {73--78}, - url = {https://doi.org/10.1145/3604951.3605513} -} -``` +* This tool is actively being developed.

A deep learning -model helps to crop to the page borders by using a pixel-wise segmentation method. - -### Column classification - -Model card: [Column Classification](https://huggingface.co/SBB/eynollah-column-classifier) - -This model is a trained classifier that recognizes the number of columns in a document by use of a training set with -manual classification of all documents into six classes with either one, two, three, four, five, or six and more columns -respectively. - -### Binarization - -Model card: [Binarization](https://huggingface.co/SBB/eynollah-binarization) - -This model is designed to tackle the intricate task of document image binarization, which involves segmentation of the -image into white and black pixels.

In the deep learning part, an image-to-image -model performs binary segmentation of the document into the classes textline vs. background. In the heuristics part, -bounding boxes or contours are derived from binary segmentation. - -In the context of this textline model, a distinct labeling approach has been employed to ensure accurate predictions. -Specifically, an artificial bounding class has been incorporated alongside the textline classes. This strategic -inclusion effectively prevents any spurious connections between adjacent textlines during the prediction phase, thereby -enhancing the model's ability to accurately identify and delineate individual textlines within documents. This model -eliminates the need for additional heuristics in extracting textline contours. - -### Table detection - -Model card: [Table Detection](https://huggingface.co/SBB/eynollah-tables) - -The objective of this model is to perform table segmentation in historical document images. Due to the pixel-wise -segmentation approach employed and the presence of traditional tables predominantly composed of text, the detection of -tables required the incorporation of heuristics to achieve reasonable performance. These heuristics were necessary to -effectively identify and delineate tables within the historical document images, ensuring accurate segmentation and -enabling subsequent analysis and interpretation. - -### Image detection - -Model card: [Image Detection](https://huggingface.co/SBB/eynollah-image-extraction) - -This model is used for the task of illustration detection only. - -### Reading order detection - -Model card: [Reading Order Detection]() - -The model extracts the reading order of text regions from the layout by classifying pairwise relationships between them. A sorting algorithm then determines the overall reading sequence. - -### OCR - -We have trained three OCR models: two CNN-RNN–based models and one transformer-based TrOCR model. The CNN-RNN models are generally faster and provide better results in most cases, though their performance decreases with heavily degraded images. The TrOCR model, on the other hand, is computationally expensive and slower during inference, but it can possibly produce better results on strongly degraded images. - -#### CNN-RNN model: model_eynollah_ocr_cnnrnn_20250805 - -This model is trained on data where most of the samples are in Fraktur german script. - -| Dataset | Input | CER | WER | -|-----------------------|:-------|:-----------|:----------| -| OCR-D-GT-Archiveform | BIN | 0.02147 | 0.05685 | -| OCR-D-GT-Archiveform | RGB | 0.01636 | 0.06285 | - -#### CNN-RNN model: model_eynollah_ocr_cnnrnn_20250904 (Default) - -Compared to the model_eynollah_ocr_cnnrnn_20250805 model, this model is trained on a larger proportion of Antiqua data and achieves superior performance. - -| Dataset | Input | CER | WER | -|-----------------------|:------------|:-----------|:----------| -| OCR-D-GT-Archiveform | BIN | 0.01635 | 0.05410 | -| OCR-D-GT-Archiveform | RGB | 0.01471 | 0.05813 | -| BLN600 | RGB | 0.04409 | 0.08879 | -| BLN600 | Enhanced | 0.03599 | 0.06244 | - - -#### Transformer OCR model: model_eynollah_ocr_trocr_20250919 - -This transformer OCR model is trained on the same data as model_eynollah_ocr_trocr_20250919. - -| Dataset | Input | CER | WER | -|-----------------------|:------------|:-----------|:----------| -| OCR-D-GT-Archiveform | BIN | 0.01841 | 0.05589 | -| OCR-D-GT-Archiveform | RGB | 0.01552 | 0.06177 | -| BLN600 | RGB | 0.06347 | 0.13853 | - -##### Qualitative evaluation of the models - -| | | | | -|:---:|:---:|:---:|:---:| -| Image | cnnrnn_20250805 | cnnrnn_20250904 | trocr_20250919 | - - - -| | | | | -|:---:|:---:|:---:|:---:| -| Image | cnnrnn_20250805 | cnnrnn_20250904 | trocr_20250919 | - - -| | | | | -|:---:|:---:|:---:|:---:| -| Image | cnnrnn_20250805 | cnnrnn_20250904 | trocr_20250919 | - - -| | | | | -|:---:|:---:|:---:|:---:| -| Image | cnnrnn_20250805 | cnnrnn_20250904 | trocr_20250919 | - - - -## Heuristic methods - -Additionally, some heuristic methods are employed to further improve the model predictions: - -* After border detection, the largest contour is determined by a bounding box, and the image cropped to these coordinates. -* Unlike the non-light version, where the image is scaled up to help the model better detect the background spaces between text regions, the light version uses down-scaled images. In this case, introducing an artificial class along the boundaries of text regions and text lines has helped to isolate and separate the text regions more effectively. -* A minimum area is defined for text regions in relation to the overall image dimensions, so that very small regions that are noise can be filtered out. -* In the non-light version, deskewing is applied at the text-region level (since regions may have different degrees of skew) to improve text-line segmentation results. In contrast, the light version performs deskewing only at the page level to enhance margin detection and heuristic reading-order estimation. -* After deskewing, a calculation of the pixel distribution on the X-axis allows the separation of textlines (foreground) and background pixels (only in non-light version). -* Finally, using the derived coordinates, bounding boxes are determined for each textline (only in non-light version). -* As mentioned above, the reading order can be determined using a model; however, this approach is computationally expensive, time-consuming, and less accurate due to the limited amount of ground-truth data available for training. Therefore, our tool uses a heuristic reading-order detection method as the default. The heuristic approach relies on headers and separators to determine the reading order of text regions. diff --git a/docs/ocrd.md b/docs/ocrd.md deleted file mode 100644 index 9e7e268..0000000 --- a/docs/ocrd.md +++ /dev/null @@ -1,26 +0,0 @@ -## Use as OCR-D processor - -Eynollah ships with a CLI interface to be used as [OCR-D](https://ocr-d.de) [processor](https://ocr-d.de/en/spec/cli), -formally described in [`ocrd-tool.json`](https://github.com/qurator-spk/eynollah/tree/main/src/eynollah/ocrd-tool.json). - -When using Eynollah in OCR-D, the source image file group with (preferably) RGB images should be used as input like this: - - ocrd-eynollah-segment -I OCR-D-IMG -O OCR-D-SEG -P models eynollah_layout_v0_5_0 - -If the input file group is PAGE-XML (from a previous OCR-D workflow step), Eynollah behaves as follows: -- existing regions are kept and ignored (i.e. in effect they might overlap segments from Eynollah results) -- existing annotation (and respective `AlternativeImage`s) are partially _ignored_: - - previous page frame detection (`cropped` images) - - previous derotation (`deskewed` images) - - previous thresholding (`binarized` images) -- if the page-level image nevertheless deviates from the original (`@imageFilename`) - (because some other preprocessing step was in effect like `denoised`), then - the output PAGE-XML will be based on that as new top-level (`@imageFilename`) - - ocrd-eynollah-segment -I OCR-D-XYZ -O OCR-D-SEG -P models eynollah_layout_v0_5_0 - -In general, it makes more sense to add other workflow steps **after** Eynollah. - -There is also an OCR-D processor for binarization: - - ocrd-sbb-binarize -I OCR-D-IMG -O OCR-D-BIN -P models default-2021-03-09 diff --git a/docs/train.md b/docs/train.md deleted file mode 100644 index 9c390bb..0000000 --- a/docs/train.md +++ /dev/null @@ -1,804 +0,0 @@ -# Prerequisistes - -## 1.

For each use case, we provide guidance -on how to generate the corresponding training dataset. - -The following three tasks can all be accomplished using the code in the -[`train`](https://github.com/qurator-spk/eynollah/tree/main/train) directory: - -* [Generate training dataset](#generate-training-dataset) -* [Train a model](#train-a-model) -* [Inference with the trained model](#inference-with-the-trained-model) - -## Training, evaluation and output - -The train and evaluation folders should contain subfolders of `images` and `labels`. - -The output folder should be an empty folder where the output model will be written to. - -## Generate training dataset - -The script `generate_gt_for_training.py` is used for generating training datasets. As the results of the following -command demonstrates, the dataset generator provides several subcommands: - -```sh -eynollah-training generate-gt --help -``` - -The three most important subcommands are: - -* image-enhancement -* machine-based-reading-order -* pagexml2label - -### image-enhancement - -Generating a training dataset for image enhancement is quite straightforward. All that is needed is a set of -high-resolution images. The training dataset can then be generated using the following command: - -```sh -eynollah-training image-enhancement \ - -dis "dir of high resolution images" \ - -dois "dir where degraded images will be written" \ - -dols "dir where the corresponding high resolution image will be written as label" \ - -scs "degrading scales json file" -``` - -The scales JSON file is a dictionary with a key named `scales` and values representing scales smaller than 1. Images are -downscaled based on these scales and then upscaled again to their original size. This process causes the images to lose -resolution at different scales. The degraded images are used as input images, and the original high-resolution images -serve as labels. The enhancement model can be trained with this generated dataset. The scales JSON file looks like this: - -```yaml -{ - "scales": [0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9] -} -``` - -### machine-based-reading-order - -For machine-based reading order, we aim to determine the reading priority between two sets of text regions. The model's -input is a three-channel image: the first and last channels contain information about each of the two text regions, -while the middle channel encodes prominent layout elements necessary for reading order, such as separators and headers. -To generate the training dataset, our script requires a PAGE XML file that specifies the image layout with the correct -reading order. - -For output images, it is necessary to specify the width and height. Additionally, a minimum text region size can be set -to filter out regions smaller than this minimum size. This minimum size is defined as the ratio of the text region area -to the image area, with a default value of zero. To run the dataset generator, use the following command: - -```shell -eynollah-training generate-gt machine-based-reading-order \ - -dx "dir of GT xml files" \ - -domi "dir where output images will be written" \ -"" -docl "dir where the labels will be written" \ - -ih "height" \ - -iw "width" \ - -min "min area ratio" -``` - -### pagexml2label - -`pagexml2label` is designed to generate labels from PAGE XML GT files for various pixel-wise segmentation use cases, -including: -- `printspace` (i.e. page frame), -- `layout` (i.e. regions), -- `textline`, -- `word`, and -- `glyph`. - -To train a pixel-wise segmentation model, we require images along with their corresponding labels. Our training script -expects a PNG image where each pixel corresponds to a label, represented by an integer. The background is always labeled -as zero, while other elements are assigned different integers. For instance, if we have ground truth data with four -elements including the background, the classes would be labeled as 0, 1, 2, and 3 respectively. - -In binary segmentation scenarios such as textline or page extraction, the background is encoded as 0, and the desired -element is automatically encoded as 1 in the PNG label. - -To specify the desired use case and the elements to be extracted in the PNG labels, a custom JSON file can be passed. -For example, in the case of textline detection, the JSON contents could be this: - -```yaml -{ -"use_case": "textline" -} -``` - -In the case of layout segmentation, the config JSON file might look like this: - -```yaml -{ -"use_case": "layout", -"textregions": {"rest_as_paragraph": 1, "drop-capital": 1, "header": 2, "heading": 2, "marginalia": 3}, -"imageregion": 4, -"separatorregion": 5, -"graphicregions": {"rest_as_decoration": 6, "stamp": 7} -} -``` - -The same example if `PrintSpace` (or `Border`) should be represented as a unique class: - -```yaml -{ -"use_case": "layout", -"textregions": {"rest_as_paragraph": 1, "drop-capital": 1, "header": 2, "heading": 2, "marginalia": 3}, -"imageregion": 4, -"separatorregion": 5, -"graphicregions": {"rest_as_decoration": 6, "stamp": 7} -"printspace_as_class_in_layout": 8 -} -``` - -In the `layout` use-case, it is beneficial to first understand the structure of the PAGE XML file and its elements. -For a given page image, the visible segments are annotated in XML with their polygon coordinates and types. -On the region level, available segment types include `TextRegion`, `SeparatorRegion`, `ImageRegion`, `GraphicRegion`, -`NoiseRegion` and `TableRegion`. - -Moreover, text regions and graphic regions in particular are subdivided via `@type`: -- The allowed subtypes for text regions are `paragraph`, `heading`, `marginalia`, `drop-capital`, `header`, `footnote`, -`footnote-continued`, `signature-mark`, `page-number` and `catch-word`. -- The known subtypes for graphic regions are `handwritten-annotation`, `decoration`, `stamp` and `signature`. - -These types and subtypes must be mapped to classes for the segmentation model. However, sometimes these fine-grained -distinctions are not useful or the existing annotations are not very usable (too scarce or too unreliable). -In that case, instead of these subtypes with a specific mapping, they can be pooled together by using the two special -types: -- `rest_as_paragraph` (mapping missing TextRegion subtypes and `paragraph`) -- `rest_as_decoration` (mapping missing GraphicRegion subtypes and `decoration`) - -(That way, users can extract all known types from the labels and be confident that no subtypes are overlooked.) - -In the custom JSON example shown above, `header` and `heading` are extracted as the same class, -while `marginalia` is modelled as a different class. All other text region types, including `drop-capital`, -are grouped into the same class. For graphic regions, `stamp` has its own class, while all other types -are classified together. `ImageRegion` and `SeparatorRegion` will also represented with a class label in the -training data. However, other regions like `NoiseRegion` or `TableRegion` will not be included in the PNG files, -even if they were present in the PAGE XML. - -The tool expects various command-line options: - -```sh -eynollah-training generate-gt pagexml2label \ - -dx "dir of input PAGE XML files" \ - -do "dir of output label PNG files" \ - -cfg "custom config JSON file" \ - -to "output type (2d or 3d)" -``` - -As output type, use -- `2d` for training, -- `3d` to just visualise the labels. - -We have also defined an artificial class that can be added to (rendered around) the boundary -of text region types or text lines in order to make separation of neighbouring segments more -reliable. The key is called `artificial_class_on_boundary`, and it takes a list of text region -types to be applied to. - -Our example JSON config file could then look like this: - -```yaml -{ - "use_case": "layout", - "textregions": { - "paragraph": 1, - "drop-capital": 1, - "header": 2, - "heading": 2, - "marginalia": 3 - }, - "imageregion": 4, - "separatorregion": 5, - "graphicregions": { - "rest_as_decoration": 6 - }, - "artificial_class_on_boundary": ["paragraph", "header", "heading", "marginalia"], - "artificial_class_label": 7 -} -``` - -This implies that the artificial class label (denoted by 7) will be present in the generated PNG files -and will only be added around segments labeled `paragraph`, `header`, `heading` or `marginalia`. (This -class will be handled specially during decoding at inference, and not show up in final results.) - -For `printspace`, `textline`, `word`, and `glyph` segmentation use-cases, there is no `artificial_class_on_boundary` key, -but `artificial_class_label` is available. If specified in the config file, then its value should be set at 2, because -these elements represent binary classification problems (with background represented as 0, and segments as 1, respectively). - -For example, the JSON config for textline detection could look as follows: - -```yaml -{ - "use_case": "textline", - "artificial_class_label": 2 -} -``` - -If the coordinates of `PrintSpace` (or `Border`) are present in the PAGE XML ground truth files, -and one wishes to crop images to only cover the print space bounding box, this can be achieved -by passing the `-ps` option. Note that in this scenario, the directory of the original images -must also be provided, to ensure that the images are cropped in sync with the labels. The command -line would then resemble this: - -```sh -eynollah-training generate-gt pagexml2label \ - -dx "dir of input PAGE XML files" \ - -do "dir of output label PNG files" \ - -cfg "custom config JSON file" \ - -to "output type (2d or 3d)" \ - -ps \ - -di "dir of input original images" \ - -doi "dir of output cropped images" -``` - -Also, note that it can be detrimental to layout training if there are visible segments which -the annotation does not account for (and thus the model must learn to ignore). So if the images -are not cropped, the `-ps` _should_ be used. If a PAGE XML file is missing `PrintSpace` (or `Border`) -annotations, use `-mps` to either `skip` these or `project` (i.e. crop from existing segments). - -## Train a model - -### classification - -For the image classification use-case, we have not provided a ground truth generator, as it is unnecessary. -All we require is a training directory with subdirectories, each containing images of its respective classes. We need -separate directories for training and evaluation, and the class names (subdirectories) must be consistent across both -directories. Additionally, the class names should be specified in the config JSON file, as shown in the following -example. If, for instance, we aim to classify "apple" and "orange," with a total of 2 classes, the -`classification_classes_name` key in the config file should appear as follows: - -```yaml -{ - "backbone_type" : "nontransformer", - "task": "classification", - "n_classes" : 2, - "n_epochs" : 10, - "input_height" : 448, - "input_width" : 448, - "weight_decay" : 1e-6, - "n_batch" : 4, - "learning_rate": 1e-4, - "f1_threshold_classification": 0.8, - "pretraining" : true, - "classification_classes_name" : {"0":"apple", "1":"orange"}, - "dir_train": "./train", - "dir_eval": "./eval", - "dir_output": "./output" -} -``` - -Then `dir_train` should be like this: - -``` -. -└── train # train directory - ├── apple # directory of images for apple class - └── orange # directory of images for orange class -``` - -And `dir_eval` analogously: - -``` -. -└── eval # evaluation directory - ├── apple # directory of images for apple class - └── orange # directory of images for orange class - -``` - -The classification model can be trained using the following command line: - -```sh -eynollah-training train with config_classification.json -``` - -As evident in the example JSON file above, for classification, we utilize a "f1_threshold_classification" parameter. -This parameter is employed to gather all models with an evaluation f1 score surpassing this threshold. Subsequently, -an ensemble of these model weights is executed, and a model is saved in the output directory as "model_ens_avg". -Additionally, the weight of the best model based on the evaluation f1 score is saved as "model_best". - -### reading order -An example config json file for machine based reading order should be like this: - -```yaml -{ - "backbone_type" : "nontransformer", - "task": "reading_order", - "n_classes" : 1, - "n_epochs" : 5, - "input_height" : 672, - "input_width" : 448, - "weight_decay" : 1e-6, - "n_batch" : 4, - "learning_rate": 1e-4, - "pretraining" : true, - "dir_train": "./train", - "dir_eval": "./eval", - "dir_output": "./output" -} -``` - -The "dir_train" should be like this: - -``` -. -└── train # train directory - ├── images # directory of images - └── labels # directory of labels -``` - -And the "dir_eval" the same structure as train directory: - -``` -. -└── eval # evaluation directory - ├── images # directory of images - └── labels # directory of labels -``` - -The reading-order model can be trained like the classification case command line. - -### Segmentation (Textline, Binarization, Page extraction and layout) and enhancement - -#### Parameter configuration for segmentation or enhancement usecases - -The following parameter configuration can be applied to all segmentation use cases and enhancements. The augmentation, -its sub-parameters, and continued training are defined only for segmentation use cases and enhancements, not for -classification and machine-based reading order, as you can see in their example config files. - -* `task`: The task parameter must be one of the following values: - - `binarization`, - - `enhancement`, - - `segmentation`, - - `classification`, - - `reading_order`. -* `backbone_type`: For the tasks `segmentation` (such as text line, and region layout detection), - `binarization` and `enhancement`, we offer two backbone options: - - `nontransformer` (only a CNN ResNet-50). - - `transformer` (first apply a CNN, followed by a transformer) -* `transformer_cnn_first`: Whether to apply the CNN first (followed by the transformer) when using `transformer` backbone. -* `transformer_num_patches_xy`: Number of patches for vision transformer in x and y direction respectively. -* `transformer_patchsize_x`: Patch size of vision transformer patches in x direction. -* `transformer_patchsize_y`: Patch size of vision transformer patches in y direction. -* `transformer_projection_dim`: Transformer projection dimension.

- Label: [ [1, 0, 0, 1, 1, 0, 0, 1, 0, 0], - [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], - ..., - [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], - [0, 0, 0, 0, 0, 0, 0, 0, 0, 0] ] - - This means that you have an image by `10*10*3` and `pixel[0,0]` belongs - to class `1` and `pixel[0,1]` belongs to class `0`. - - A small sample of training data for binarization experiment can be found here, [Training data sample](https://qurator-data.de/~vahid.rezanezhad/binarization_training_data_sample/), which contains images and lables folders. -

Image enhancement can also take place without this option, but by setting this option to `true`, the layout xml -data (e.g. coordinates) will be based on the resized and enhanced image instead of the original image. -* For some documents, while the quality is good, their scale is very large, and the performance of tool decreases.

With this -setting, the tool can currently distinguish 7 document layout classes/elements. -* In cases where the document includes curved headers or curved lines, rectangular bounding boxes for textlines will not -be a great option. In such cases it is strongly recommended setting the flag `-cl` (**c**urved **l**ines) to `true` to -find contours of curved lines instead of rectangular bounding boxes. Be advised that enabling this option increases the -processing time of the tool. -* To crop and save image regions inside the document, set the parameter `-si` (**s**ave **i**mages) to true and provide -a directory path to store the extracted images. -* To extract only images from a document, set the parameter `-eoi` (**e**xtract **o**nly **i**mages).
