- Abstract:
-
In intelligent video surveillance systems, the moving cast shadows are often mistaken as the object due to its own properties. Consequently, a YUV color spacebased theory and a graphtheorybased shadow detection method were proposed to improve the quality of detection. First, the precise seeds of the foreground and shadow were obtained by the YUV color space based on the comprehensive consideration of luminance and chrominance information and morphological filtering. Then the maximum flow minimum cut graph theory algorithm was employed to obtain the optimized segmentation of the shadow and target. Experimental results show that the proposed method can detect and eliminate the cast shadow effectively.
