Canny算子与小波变换相结合的道路边缘特征提取算法

Road edge feature extraction algorithm with Canny operator and wavelet transform

提出了Canny算子与小波变换相结合的道路边缘特征提取算法。首先用Canny算子对原图像提取边缘,与原图像进行叠加,再用小波变换对此图像进行二次边缘提取,有效地提取道路边缘特征,避免了Canny算子提取道路边缘不连续现象和小波变换提取边缘时出现的虚假边缘信息。

A road edge feature extraction algorithm based on Canny operator and wavelet transform is proposed in this paper, the edge of the original image is extracted by using Canny operator, overlay？？it on the original image, and then extract edge of the overlaid image by using wavelet transform. This algorithm can effectively extract the edge features of the road , and avoid the road edge discontinuity phenomena of Canny operator and the false edge information of wavelet transform.
