This ImageJ plugin demonstrates the use of the CorrCoeffMatcher class. The active (grayscale) image is taken as the search image. The reference (template) image is extracted from the required rectangular selection (ROI) in the search image and then corrupted by Gaussian noise with user-specified sigma. The correlation coefficient matcher is quite resistant to high noise levels. Detected matches are shown as graphic overlays on the input image. Also, the matching score surface and its local maxima are optionally displayed. See Sec. 23.1.1 (Alg. 23.1) of [1] for additional details on correlation coefficient matching.
