Abstract: Aiming at the failure of traditional background subtraction in the moving detection when the moving object is similar in color with the background,a complete motion objects detection method is proposed.The method selects independent thresholds for the three channels of the YUV color space to do the first detection,making full use of the image color information in the video.A second detection is performed in the smallest rectangle area that contains the first detected moving object to improve the detection accuracy effectively.Experiments demonstrate that the detection results by this method are more clear and complete than those by the traditional method.
