摘　　要：边缘检测在数字图像处理中有着重要的应用。边缘是图像的最基本特征。该文利用Sobel算子对图像进行水平和垂直的边缘提取,并对图像进行MATLAB仿真比较,仿真实验表明,该方法对图像边缘的检测精度较高,抗噪声能力强,提高了图像边缘检测效果。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.
