What is normalized cross correlation?
Description. Normalized Cross-Correlation (NCC) is by definition the inverse Fourier transform of the convolution of the Fourier transform of two (in this case) images, normalized using the local sums and sigmas (see below).
How does SSD template matching work?
In the SSD template matching method, the measurement of compatibility is based on the degree of difference in pixel intensity between the two images (template and input image). The principle of this method is to squeeze the results of the reduction of each pixel between the input image and the template.
