摘要
图像的边缘中包含有图像的大部分信息,并且图像边缘检测是图像处理与分析的关键性步骤,也是模式识别与计算机视觉领域的主要研究内容之一,因此,研究边缘检测算子对图像处理十分重要。运用MATLAB对Sobel算子、LOG算子及Canny算子三种常用的边缘检测算子进行了仿真实验,分析了其各自的优缺点,得出Canny算子是三种算子中边缘检测效果最好的边缘检测算子。为今后的实际应用,选择合适的算子提供了参考依据。
The edge of the image contains mott of the information of the image,and image step in image processing and analysis. It s also one of the main research contents in the field of pattern recognition and computer vision. Therefore,the study of edge detection operator 狊 of great significance. Several kinds of commonly used edge detection operators are emulated by MATLAB, and their advantages and disadvantages are analyzed. It pro-vides a reference for future practical application and selection of appropriate operators.
