12 December 2015 1 699 Report

I have an image and i want to apply autocorralation function on it, In MATLAB. Multiple command are in MATLAB for autocorralation, ex xcorr2, autocorr, ... and a function: abs(fftshift(ifft2(fft2(H).*conj(fft2(image))))).

Which one i must use for my purpose and how can i draw a curve similar attached image from result of autocorrelation?

thanks

I find it, autocorr is that.
