Edge Detection

Edge detection methods for finding object boundaries in images

Edge detectionis an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. Edge detection is used forimage segmentationand data extraction in areas such as image processing,computer vision, and machine vision.

Commonedge detection algorithmsinclude Sobel, Canny, Prewitt, Roberts, andfuzzy logicmethods.
