WebMay 17, 2024 · An edge can be defined as a set of connected pixels that forms a boundary between two disjoint regions. There are three types of edges: Horizontal edges; Vertical edges; Diagonal edges; Edge Detection is a method of segmenting an image into regions of discontinuity. It is a widely used technique in digital image processing like WebEdge detection is an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. Edge detection is used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision.
