The two images are from DIBCO (Document Image Binarization Contest). The objective is to find a solution to binarize the top image (original image) to be similar to the bottom one (ground-truth image).

But if I want to make my own ground-truth image for my document image, how do I do it? Any idea, method, or technique is appreciated.

  • $\begingroup$ @MimSaad Polish image in pixel level is definitely nightmare, although I cannot think of any better method. $\endgroup$ – Ksiau Aug 13 at 2:45
