An edge detection algorithm for mine roadway image

Gong-kuang zidonghua, 2013
In view of problem of bad edge extraction effect when traditional Canny algorithm processes fuzzy mine roadway image, the paper proposed an edge detection algorithm for mine roadway image based on wavelet transform and Canny algorithm. The algorithm firstly makes wavelet decomposition for original mine roadway image to obtain low-frequency image and ...
