Hi

I have some tiff images where I have to make autocorrelation on. I have
tried it but I think that math. is very slow.

The images/matrix is 480x360 pixels.

I am using fourier transformation and inversfourier transformation to make
the autocorrelation.



Is there any body that has experience with this using mathematica?



best regards



Mikael
