A Comprehensive Review On Different Edge Detection Techniques
Sumeet Kaur · 2012
Edge detection is one of the most commonly used operations in image analysis and is also an essential pre-processing step in image segmentation. An edge is the boundary between an object and the background, and indicates the boundary between adjacent parts of image and overlapping objects. Here we are reviewing several techniques for edge detection like Sobel operator technique, Prewitt technique, Fuzzy Edge Detection technique, Canny technique, Roberts technique and Morphology based multi structure elements edge detection technique.
