Hi,

does anybody know if there exist a function to calculate the autocorrelation of an image?

Thanks

Igor

If you are going to work with images you might benefit from reading the Image Processing Tutorial. You can find it under File Menu->Example Experiments->Tutorials.

In general 2D convolutions and correlations are computed using FFT/IFFT. Radial averaging can be computed the hard way (direct pixel averaging of the autocorrelation) or using ImageLineProfile with a radial path and non-zero width.
