OpenCV comes with a function cv.matchTemplate() for this purpose. It simply slides the template image over the input image (as in 2D convolution) and compares the template and patch of input image under the template image. Several comparison methods are implemented in OpenCV. (You can check docs for more details).

Multi scale Template Matching using Python and OpenCV ... Apply template matching using cv2.matchTemplate and keep track of the match with the largest correlation coefficient (along with the x, y coordinates of the region with the largest correlation coefficient). After looping over all scales, take the region with the largest correlation coefficient and use that as your “matched” region. OpenCV: cv::cuda::TemplateMatching Class Reference image: Source image. templ: Template image with the size and type the same as image . result: Map containing comparison results ( CV_32FC1 ). If image is W x H and templ is w x h, then result must be W w 1 x H h 1.: stream Object tracking with OpenCv’s TemplateMatching | Matt Bell ...
