Template matching using fast normalized cross correlation
WebThe peaks in this cross correlation "surface" are the positions of the best matches in the image of the mask. Issues. The process can be extremely time consuming, the 2D cross correlation function needs to be computed for every point in the image. Calculation of the cross correlation function is itself a N 2 operation. Webnormalized cross-correlation for analytic signals. Learn more about cross-correlation, analytic signal . I am trying to write a function for template matching using normalized cross-correlation.
