Hi, Could anybody tell me how to shift the 2D cross correlation result in matlab. For example, in 1D cross correlation, the result of cross correlation will be twice of the maximum signal length minus 1, which then the first half of the graph will be padded to zero. The result will spread from right to left according to the length of signal to be correlated. From this, we can plot the graph back to its right location (in term of peak location) by using the code below; %If there are signals of x and y doing the cross correlation k=xcorr(x,y); N=max(length(x)-1,length(y)-1); p=(1:2*N)-N; plot(p,k) %the result of cross correlation will shift back to get the correct %location of peak My question is how can we do this in 2D cross correlation since the length of signals are in 2D array? Thanks, Sangthong
