OpenCV: Template Matching

WebThe conventional method of template matching uses cross correlation algorithms. The method is simple to implement and understand, but it is one of the slowest methods. Furthermore, if the object in the image is rotated, the tradition method can fail. In this paper, an algorithm for a rotation invariant template matching method is proposed.
