摘要
介绍了几种常用的边缘检测算子。不同的微分算子对不同边缘检测的敏感程度不同,因此对不同类型的边缘提取应采用对此类边缘敏感的算子。针对受虫害杨树叶片图像,通过MATLAB 7.1进行仿真研究,通过比较,选出合适的方法。
Introduced a few operators based on edge detection briefly. Sensitivity is different for different operators, so different types of edge detection must adopt corresponding sensitive operator. The images of pest polar blades were simulated by MATLAB 7.1. The characters and functions of the operators were compared and analyzed, and the suitable method had elected from it.
