WebMay 2, 2024 · Hough transform. Hough transform is an algorithm used to detect straight lines in images. It usually takes the output of an edge detection algorithm as an input (in our case, we use Canny for that). To find lines in an image, the algorithm maps the edge points in an image onto the polar coordinate system. But what are polar coordinates?
