How does canny edge detection work

WebAug 25, 2024 · Edge detection is used to identify the edges in an image to make image processing easy. Edge detection works by detecting discontinuities in brightness. Edge detection is mainly used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision. WebCanny Edge Detection is one of the most popular edge-detection methods in use today because it is so robust and flexible. The algorithm itself follows a three-stage process for extracting edges from an image. Add to it image blurring, a necessary preprocessing step to reduce noise. This makes it a four-stage process, which includes:
