Web1 de out. de 2013 · It seems so to be that opencv does not support angle and scale invariant template matching? Cheers, Gordon Comments that's right. template matching is neither scale nor rotation invariant. (that's why there's all those SURF/SIFT/ORB things) what do you actually want to do ? berak (Oct 1 '13) edit Hi, WebIf enough matching points are found (10 here), they can be passed to find the perspective transformation (which is a 3X3 matrix). The query image (with persepctive transformation applied) is considered to have been found in the frame. Locations of all the pairs of matching points are connected with lines to show match.
