| 摘 要： | 边缘检测一直以来都是一种不适定问题。本文旨在通过三种不同的边缘检测方法对具有两种不同的噪声的图像检测结果进行比较,并分析孰优孰劣。另外特别比较了经过高斯滤波后Sobel算子与高斯-拉普拉斯算子的检测效果,并且提出一种修改的Sobel算子,对实际操作中工作效率的提高起到一定的作用。

| Abstract: | Edge detection is an uncertainty problem.The paper intends to know which is the better way through comparing the results of image detection with two kinds of noise by three edge detection ways.Especially the paper compares the detection results detected with Sobel operator after Gaussian filtering and Gauss-Laplace,respectively,and offers a better Sobel operator.It has good effect on the efficiency in practical work. |
