WebInput image, specified as a numeric image. A must be larger than the matrix template for the normalization to be meaningful.. Normalized cross-correlation is an undefined operation in regions where A has zero variance over the full extent of the template. In these regions, normxcorr2 assigns correlation coefficients of zero to the output C. WebJan 7, 2013 · This function looks like it is primarily designed to be used to produce a metric (not sure which part of the cross correlation produces the metric) for scanning an image for pattern recognition. Makes sense. Which moves me to part 2: 2D Cross Correlation can be preformed in two ways by convolution or 2D FFT multiplication.
