Normalized cross correlation原理
WebStep 3: Do Normalized Cross-Correlation and Find Coordinates of Peak. Calculate the normalized cross-correlation and display it as a surface plot. The peak of the cross-correlation matrix occurs where the subimages are best correlated. normxcorr2 only works on grayscale images, so we pass it the red plane of each subimage.
