融合色彩比和梯度不变性的运动阴影检测
Moving shadow detection based on color ratio and texture invariance
摘要
Abstract
To solve the disturbances caused by moving shadows in accurate segmentation of moving object, a moving shadow detection algorithm based on color ratio and texture invariance is proposed. The algorithm analyzes the illumina-tion invariance of the pixel color ratio and region texture gradient, and uses brightness change characteristics and color constancy to detect shadow pixels preliminarily in moving object region in pixel level. Then it utilizes texture gradient invariance to eliminate mistakenly identified shadow region at the regional level. The combination of the two types of fea-tures can make up for the defect of poor performance of shadow detection method based on a single feature or single type characteristics, and improve the detection and resolution ratio of moving shadow. The proposed algorithm can distinguish moving shadows and objects under different scenes.关键词
