摘要
对Canny边缘检测算法的性能进行了分析和评价。针对Canny算法的缺陷,提出用自适应空间域平滑方式清除图像中的椒盐噪声;用图像灰度共生矩阵的惯性矩特征值自适应调整高斯空间系数和边缘检测阈值,实现了图像边缘的自动提取。
The capability of edge detection using Canny algorithm is analyzed and evaluated in this paper. In order to avoid the defects of Canny algorithm, we propose an new way to remove shot noises in image by self-adaptable smoothness.And by using variance of gray-scale to auto-adjust Gassian space coefficient and edge detection threshold, the image edge can be automatically detected.This method proves efficient in practice.
