Abstract

An edge in an image is the boundary between two different regions. Edge detection is important in image processing and computer vision, particularly in the area of feature detection. An edge often indicates the physical extent of object within the image. An edge detection process ultimately aims to obtain a binary edge map. In this paper, we propose a new scheme for edge detection. It is simple but efficient and works well for the images that have large jumps between the values of an element and its neighbors.
