 This tool performs document layout analysis (segmentation) from image data and returns the results as [PAGE-XML](https://github.com/PRImA-Research-Lab/PAGE-XML).
 
 It can currently detect the following layout classes/elements:
-* Border
-* Textregion
-* Image
-* Textline
-* Separator
-* Marginalia
-* Initial (Drop Capital)

+* [Textregion](https://ocr-d.de/en/gt-guidelines/pagexml/pagecontent_xsd_Complex_Type_pc_TextRegionType.html)

-In addition, the tool can be used to detect the _Reading Order_ of regions. The final goal is to feed the output to an OCR model.

 The tool uses a combination of various models and heuristics (see flowchart below for the different stages and how they interact):
