Fred's ImageMagick Scripts: FFTDECONVOL. USAGE: fftdeconvol [-n noise] infile filtfile outfile USAGE: fftdeconvol [-h or -help] -n .... noise .... estimate of the noise to signal power ratio; float>=0; .................. default=0 PURPOSE: To perform deconvolution on an image in the frequency domain. DESCRIPTION: FFTDECONVOL perform deconvolution on an image in the frequency domain using a filter image and an estimate of the noise to signal power ratio.
Two inputs are required. The convolved image and a grayscale spatial domain convolution filter. Both the convolved image and the grayscale spatial domain convolution filter are transformed to the frequency domain using +fft. -n noise ... The filter image must be appropriately centered and padded with black to the same size as the input image. REQUIREMENTS: IM version 6.5.4-7 or higher, but compiled with HDRI enabled in any quantum level of Q8, Q16 or Q32. LIMITATIONS: This script works well only with even, square images.
