摘要
通过对Canny算子进行边缘检测的过程分析,指出采用高斯模板对图像进行滤波会造成图像的过度平滑并导致图像中弱边缘的丢失,使得Canny算子的弱边缘检测能力降低。提出采用自适应平滑与增强方式对图像进行处理,在平滑图像区域内部的同时对图像边缘进行了增强,提高了Canny算子进行弱边缘检测的能力。
The analysis of Canny detector indicates that image excess smoothing and the feebleness edge will lose by using Gauss template to filter it, this leads to depress the capability for detecting the feebleness edge. In this paper, an adaptive smoothing and enhancement method are put forward to filter image to smoothed image, at the same time, to enhance the edge. This method can improve the capability of Canny to detect feebleness edge.
