Graff appeared for me as a useful appllication. As I know the philosophers' stone of such kind applications is denoising. While experimentig with Graff, I couldn't acheive such a results, as you have at the homepage (the third example). Could you post please a denoising tutorial ?
P.S. It will be also nice to see a DeBlur tutorial
