基于Matlab的数字图像边缘检测研究

本文依托Matlab对数字图像边缘检测进行研究,并介绍了四种基本边缘检测算子,分别是Sobel算子、Roberts算子、Log算子以及Canny算子,通过对同一灰度值图像进行处理,并且加入图像腐蚀膨胀操作,比较实验结果,并对其进行分析,对Matlab在数字图像边缘检测应用于生活实际中提供一定的参考。

This paper relies on Matlab to study the edge detection of digital images,and introduces four basic edge detection operators,namely Sobel operator,Roberts operator,Log operator and Canny operator,by processing the same gray value image,and add image erosion and dilation operation,compare the experimental results,and analyze them,which provides a certain reference for the application of Matlab in digital image edge detection in real life.
