After analyzing the texture and color property of shadow points,an optimization shadow detection algorithm is proposed.Tthe new approach combines local texture and the color information to detect shadow.Firstly,in order to represent texture better,LBP is modified,and then the improved LBP is used to obtain candidate shadow region.Secondly,the mean and variance of the brightness ratio of candidate shadow region is calculated,the statistic is used to remove non-shadow points.Finally,a complete shadow region is obtained by region grow.The experimental results prove its validity and accuracy in various fixed outdoor scenes.
