Nowadays, video is a primary information carrier in www (world wild web) and moving objects are often carrying more information. But it is hard to catch these objects in video quickly and correctly. In this paper, we put forward a method to catch moving object in video. Firstly, based on difference image method, we determine moving region in video image. To avoid hardness to build background, we build background with a new algorithm based on difference changed. Finally, we get the objects and denoise them with erosion and dilation. The experimental result is shown that the new method is feasibility and high quality.
