Hough transform to detect rectangle

WebIn this case, we can use the Hough (line detecting) transform to detect the eight separate straight lines segments of this image and thereby identify the true geometric structure of the subject. If we use these edge/boundary points as input to the Hough transform, a curve is generated in polar space for each edge point in cartesian space.
