Research on Video Object Extraction Technology

Abstract—As the application of intelligent video surveillance system is more and more widely, the scale is also expanding with it. People is also more and more getting attention of the video object extraction which is the key technology in the intelligent video surveillance and attracted plenty of experts and scholars at home and abroad to study. This paper is mainly studying on the video object extraction under the static background, introduces the typical moving object extraction algorithms, analyzes and compares the advantages and disadvantages of various algorithms. We proposed a method which combines the background difference method with the Surendra background update algorithm. Experimental results show that the algorithm can detect the moving objects more efficiently. Keywords-video object;object extraction;inter-frame difference; optical flow;background subtraction I
