Document Binarization Evaluation for LRDE DBD
scanned, magazine, documents, binarization
Pixel-wise evaluation: binarization outputs are compared to binarization ground-truth, pixel-wise. It is performed from binarization of “clean documents”.
Purpose of the three document qualities :
- Original : evaluate the binarization quality on perfect documents mixing text and images.
- Clean : evaluate the binarization quality on perfect document with text only.
- Scanned : evaluate the binarization quality on slightly degraded documents with text only.
Binarization algorithms should handles PNG format as input and output images.
Binarization outputs must set background to False and objects to True.
Tools are provided to read and process all the data.
