Description

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.
