Opencv template matching false positive
WebHello everyone, I am trying the simple template matching function matchTemplate. However I'm still having a hard time understanding how to extract the "overall" matching coefficient score for the instance. I know that depending on the method used, the coefficient varies 0-1 or -1 to 1 and each pixel is having a similarity index in result matric.
