This paper proposes a shadow removal method based on edge feature.By using the edge information of the shadow which is obtained by edge detection algorithm the shadow of moving vehicle is removed by edge difference analysis and morphological operations.Then,a shadow removal method based on gray feature is proposed,which remove the shadow of vehicle using Gaussian darkening factor model.Combined with the advantages of two methods,a method of shadow removal for moving vehicle based on multiple feature fusion is proposed.It can effectively solve the problem of wrong detection caused by complex edges in shadow region and the similar color between vehicle and shadow.The testing results demonstrate that by using the proposed method shadow removal can be realized with real-time performance,strong robustness and high accuracy.
