WebCanny Edge Detector. Common Names: Canny edge detector Brief Description. The Canny operator was designed to be an optimal edge detector (according to particular criteria --- there are other detectors around that also claim to be optimal with respect to slightly different criteria). It takes as input a gray scale image, and produces as output an …
WebDec 6, 2024 · An example would be if the data is known to be simple and predictable; a Canny Edge Detector would work right out of the box … WebAug 29, 2024 · Perform Canny edge detection on the image g (x, y) to obtain the edge detection result G (x, y) and record the upper threshold k 1. When the pixel is the edge of the image, K tends to be 1, which makes the diffusion speed of the P-M equation slow down and preserve the image details.
