Edge detection in the digital image processing has important applications. Edge is the most basic features of the image. In this paper, Sobel operator to the image horizontal and vertical edge detection, and image comparison MATLAB simulation, simulation experiments show that the method has high precision in image detection, anti-noise ability and improving the image edge detection.
