摘要
MATLAB软件工具箱中,提供了edge函数,它能利用多种算子进行图像的边缘检测,语言结构简单。本文就数字图像处理中几种常用的用于检测的算子(Roberts算子、Prewitt算子、Sobel算子、log算子、Canny算子),通过MATLAB软件来实现遥感图像的边缘检测,对抗噪声能力进行分析,得出各自的优缺点和适用范围。
Image Processing MATLAB Toolbox User＇s Guide,Has provided the edge function,It can use many kinds of operators to carry on the image the edge examination.Several common edge detection operators（Sobel operator、Prewitt operator、Sobel operator、Log operator and Canny operator） in digital processing can be achieved through MATLAB and the detection effect and anti-noise ability of each operator are analyzed to clarify the advantages and disadvantages and the scope of application.
