Abstract :
In this paper, based on the mixed Gaussian modeling and segmentation of moving objects and shadow, we propose an adaptive threshold shadow detection method based on image block statistics. The experiments of the video sequences with the different light and environmental conditions show that the method can remove the shadow of the moving target very well, and it also can choose the threshold adaptively.
