Dear members,
in order to convolve a greyscale image with a gaussian I used FFTW code (release 3.1.1) to work in fourier domain. In detail my initial data is lying on a 1000x10000 point grid, correspondingly I put the gaussian bell on a 1000x1000 grid too. The gaussian distribution is normalized...
