scanned, magazine, documents, binarization
125 binarized images for "clean documents".
Image groundtruths have been produced using a semi-automatic process: a global thresholding followed by some manual adjustments.
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.
