just run: python train.py with config_params.json

# Ground truth format

|

Lables for each pixel is identified by a number . So if you have a
|
||||
binary case n_classes should be set to 2 and
|
||||
labels should be 0 and 1 for each class and pixel.
|
||||
In the case of multiclass just set n_classes to the number of classes
|
||||
you have and the try to produce the labels
|
||||
by pixels set from 0 , 1 ,2 .., n_classes-1.
|
||||
The labels format should be png.
|
||||
|
||||
If you have an image label for binary case it should look like this:

# Pixelwise Segmentation
|
||||
> Pixelwise segmentation for document images
|
||||
|
||||
## Introduction
|
||||
This repository contains the source code for training an encoder model for document image segmentation.
|
||||
|
||||
## Installation
|
||||
Either clone the repository via `git clone https://github.com/qurator-spk/sbb_pixelwise_segmentation.git` or download and unpack the [ZIP](https://github.com/qurator-spk/sbb_pixelwise_segmentation/archive/master.zip).
|
||||
|
||||
## Usage
|
||||
|
||||
### Train
|
||||
To train a model, run: ``python train.py with config_params.json``
|
||||
|
||||
### Ground truth format
|
||||
Lables for each pixel are identified by a number. So if you have a
|
||||
binary case, ``n_classes`` should be set to ``2`` and labels should
|
||||
be ``0`` and ``1`` for each class and pixel.
|
||||
|
||||
In the case of multiclass, just set ``n_classes`` to the number of classes
|
||||
you have and the try to produce the labels by pixels set from ``0 , 1 ,2 .., n_classes-1``.
|
||||
The labels format should be png.
|
||||
|
||||
If you have an image label for a binary case it should look like this:
|
||||
|
||||
Label: [ [[1 0 0 1], [1 0 0 1] ,[1 0 0 1]],
|
||||
[[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ,
|
||||
[[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ]
|
||||
This means that you have an image by 3*4*3 and pixel[0,0] belongs
|
||||
to class 1 and pixel[0,1] to class 0.
|
||||
|
||||
# Training , evaluation and output
|
||||
train and evaluation folder should have subfolder of images and labels.
|
||||
And output folder should be empty folder which the output model will be written there.
|
||||
This means that you have an image by `3*4*3` and `pixel[0,0]` belongs
|
||||
to class `1` and `pixel[0,1]` belongs to class `0`.
|
||||
|
||||
# Patches
|
||||
### 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.
|
||||
|
||||
if you want to train your model with patches, the height and width of
|
||||
patches should be defined and also number of
|
||||
batchs (how many patches should be seen by model by each iteration).
|
||||
In the case that model should see the image once, like page extraction,
|
||||
the patches should be set to false.
|
||||
# Pretrained encoder
|
||||
Download weights from this link and add it to pretrained_model folder.

||||
