| Abstract: | Snake algorithm,(active contour model) is widely used in image processing.At first,an algorithm of moving shadows detection based on the normalized mutual correlation coefficient is proposed.Then using the method of inter-frame difference the object's contour points are obtained.The initial position of Snake is set automatically.The converged contour of the final object is got by using greedy algorithm.Experimental results show that the algorithm can quickly and exactly detect the multiple moving objects and suppress the shadows. |
