<DIV>Hi guys,</DIV>
<DIV> </DIV>
<DIV>I would like to implement cross correlation between a fixed image and a moving image. </DIV>
<DIV> </DIV>
<DIV>I was thinking to use the cross-correlation defined by FFT. Does anyone know if something has already been done on implementing correlation or convolution between two images by FFT?</DIV>
<DIV> </DIV>
<DIV>Thanks for help, </DIV>
