In Reply to: Cross-correlation by FFT and Gaussian interpolation posted by Alex Liberzon on June 23, 1998 at 09:47:06:
: I'm looking for Fortran/C codes on three subjects:
: 1. Fast Fourier Transform of matrices about 1000 x 1000
: 2. Cross-correlation between two matrices by FFT
: 3. Gaussian interpolation, that will help to search
: maximum value of the cross-correlation.
is a multidimensional fft in C.
Hope this help
