Moving vehicles segmentation is the most fundamental and vital problem in the intelligent transportation *** paper proposes a moving vehicles segmentation method that combines the semi-fuzzy cluster algorithm under the guidance of edge-based information with the traditional background subtraction *** all,the current frame image that involves moving vehicles is divided into two parts using the algorithm of edge detection and edge *** part is the set of edge pixels and the other one is the regions encircled by the edge *** then,every edge pixel will be associated into the most reasonable region according to the semi-fuzzy cluster *** last,the regions that similar with the background will be deleted and the remained regions are the moving vehicles in the current *** experiments show that the new method posed in this paper is more robust and exact,and have a high ability of anti noise together with a high application value.
