How Edge Detection Works

Edge detection works by detecting discontinuities in brightness. It is used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision.

Common edge detection algorithms include Sobel, Canny, Prewitt, Roberts, and fuzzy logic methods.
