Hi, I got critics so I made it better ;-) My Richardson-Lucy implementation now allows to set a mask. This mask is intended to specify the zone where the focus is supposed to be, and thus compute the deconvolution matrix estimation only there. This matrix is then used to deconvolute the whole picture. I got faaar better results regarding the general smudginess/sharpness ratio : https://github.com/aurelienpierre/Image-Cases-Studies/commit/bfaf6930abd873e568ee12f90427dad0206d6de6
I don't know how much the community is interested in my experiments though or if it's relevant here, so just tell me if I spam.
