WebJul 7, 2024 · The Canny Edge Detector is an edge detection operator that is used to detect a wide range of edges in images. It uses a multi-stage algorithm to do so. … The Sobel operator is used in image processing and computer vision , particularly within edge detection algorithms where it creates an image emphasising edges. WebThe Canny method differs from the other edge-detection methods in that it uses two different thresholds (to detect strong and weak edges), and includes the weak edges in the output only if they are connected to strong edges. This method is therefore less likely than the others to be affected by noise, and more likely to detect true weak edges.
