| Abstract: | The detection and silhouettes extraction of motion human body is a very important part in video signal processing. It is the foundation of behavior comprehending and analyzing, which has been widely used in traffic control, bank surveillance and computer vision. According to the characters of the motion human body, an algorithm with adaptive background updating, which could detect the motion human body and extract the silhouettes, is proposed based on the background subtraction and Sobel operator. Experimental result shows that this algorithm has good operation effect. |
