WebThen we use goodFeaturesToTrack () function to find corners in the image. In this function we have used corner Harris detection algorithm to detect corner in the image. The coordinate of image corners are stored in corners variable. Out of this coordinates in corner variable we find corners at sub-pixel level using cv::cornerSubPix () function.
