Web2 nov. 2007 · I am using deconvwnr.m to deconvolve a known blur to the standard cameraman.tif matlab image. I do not add any noise. The initial result is good. However if I then scale the image by x100, apply the same blur, and then deconvolve using deconvwnr, the result becomes more blurred. Web7 mei 2016 · Accepted Answer.
