Imshow abs fft2 histeq i1

Witryna23 wrz 2024 · It obtains an initial estimate of the crosscorrelation peakby an FFT and then refines the shift estimation by upsampling the DFTonly in a small neighborhood of that estimate by means of amatrix-multiply DFT. With this procedure all the image points are used tocompute the upsampled crosscorrelation.
