Web3 Nov 2010 · 1. Keshan, it is simple. Imagine the FFT is another two pictures where low frequencies lie in the middle and high frequencies away from the middle. If the pixels are numbered from -w/2 to w/2 and -h/2 to h/2 you can simply measure the distance from the middle as a (x,y)=sqrt (x^2+y^2). http://rodolphe-vaillant.fr/entry/70/laplacian-smoothing-c-code-to-smooth-a-mesh team spirit day images
