; 文章编号:1672-7207(2011)S1-0717-07 People detection algorithm based on feature of edge type ratio GU Shuang, CHEN Qi-jun (Robotics and Intelligent system Laboratory, Tongji University, Shanghai 201804, China) Abstract: A people detection algorithm based on the stereo vision is proposed and a new feature which describes the ratio of edge types in a certain area......
of overlap coal particle in the image segmentation of coal piles, several image enhancement and edge detection methods were contrasted. An algorithm combined with contrast limited local histogram equalization (CLAHE) and SUSAN edge detection was used to detect the edges of coal particles. Mathematical morphology and filling algorithm were used to obtain the best seed regions, which was able......
