For gray-scale images, edges are defined as the discontinuity in the brightness function, whereas in color images they are defined as discontinuities along adjacent regions in the RGB color space.

There are many methods for edge detection, but most of them can be grouped into two categories, search-based and zero-crossing based. The search-based methods detect edges by first computing a measure of edge strength, usually a first-order derivative expression such as the gradient magnitude, and then searching for local directional maxima of the gradient magnitude using a com… Web3 hours ago · i've been trying to detect lines of a matplotlib.pyplot image representing a floorplan. But when tweaking the hyperparameters of cv2 I either get a lot of random lines or no lines at all I've no idea what i'm doing wrong. The image contains colored shapes without noise so I can't image why the detection is failing.
