摘要：Edge detection is a very important as well as essential method in digital image processing and computer vision.It is a widely used technique in image processing for edge detection of different Gray-scale and color image. There are various methods for edge detection. The goal of edge detection is to mark the points in a digital image at which the luminous intensity changes sharply. Sharp changes in image properties usually reflect important events and changes in properties of the world. These include discontinuities in depth, discontinuities in surface orientation, changes in material properties and Variations in scene illumination. In this paper, a new method for edge detection of images is presented. Here, an improved method for edge detection (Upper constructor with LOG operator) has compared with morphological operator, specifically for the edge detection of brighter satellite images.
