Fast Fourier Transform
CImg 1.0.8 final will contain a Fast Fourier Transform routine. Well, this is a good news since I think CImg lacked for such a popular frequency analysis tool.
Functions CImg::get_FFT() and CImgl::FFT() has been added. There are surely lot of optimizations to do, but the FFT is
fast enough to be usable for image filtering. A little demo using FFT-based filtering has been added in the 'CImg_test.cpp' file. It allows the user to create a frequency filter and see the effect on an image.
