Abstract: Edge detection is a technique of image processing used to identify points in a digital image with discontinuities, simply to say, sharp changes in the image brightness. Edge detection algorithm finds numerous applications in image segmentation and data extraction in areas such as image processing, computer vision, and machine vision In This paper, certain important methods on edge detection generally applied in image preprocessing has been presented. A detailed analysis of various edge detection algorithm has been covered with suitable illustration were ever necessary. The paper also serves as aid for researchers working in this direction.
Key Words: Edge, Image Processing, Edge Detection.
