Corner detection using Opencv

 In this project,corners are regions in the image with large variation in intensity in all the directions.Sometimes, you may need to find the corners with maximum accuracy. OpenCV comes with a function.which further refines the corners detected with sub-pixel accuracy.As usual, we need to find the Harris corners first. Then we pass the centroids of these corners (There may be a bunch of pixels at a corner, we take their centroid) to refine them. Harris corners are marked in red pixels and refined corners are marked in green pixels. For this function, we have to define the criteria when to stop the iteration. We stop it after a specified number of iterations or a certain accuracy is achieved, whichever occurs first. We also need to define the size of the neighbourhood it searches for corners.
