Background difference method is the use of images in the sequence of the current frame and the background reference model is a method to detect the movement of objects, its performance depends on background modeling technology used. Background subtraction method to detect moving objects fast, accurate detection, easy to implement, the key is to get the background image. In practice, the background is still difficult to obtain directly, while, due to the dynamic changes of the background image, through inter video sequence information to estimate the background and restore that background reconstruction, so to selectively update the background.
