Autocorrelation of an image

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.
