imProcessCrossCorrelation

Calculates the Cross Correlation in the frequency domain. \n * CrossCorr(a,b) = IFFT(Conj(FFT(a))*FFT(b)) \n * Images must be of the same size and only target image must be of type complex. * * \verbatim im.ProcessCrossCorrelation(src_image1: imImage, src_image2: imImage, dst_image: imImage) [in Lua 5] \endverbatim * \verbatim im.ProcessCrossCorrelationNew(image1: imImage, image2: imImage) -> new_image: imImage [in Lua 5] \endverbatim * \ingroup transform
