Question about inferring a 2D filter from its frequency spectrum
Date:Wed, 8 Oct 2008 01:08:16 +0100
Dear all, I am working on a 2D convolution problem. I have estimated the frequency spectrum |H(u, v)| now I wish to infer the 2D filter f(x, y). I just don't know a way to work it out from the spectrum, although I may have several constraints of f(x, y) in the spatial domain forassistance. It will also be helpful if there's a good way to easily compute derivative d|H(u, v)|/df(x, y), that I can optimize f(x, y) in the spatial domain. Any ideas? Thanks!
