I believe Gaussian Mixture Models are usually/often used for background estimation in many videos. Sorry I don't have any demo code for you but look up examples in the Computer Vision System Toolbox.

The step() method of vision.ForegroundDetector takes the video frame and returns the foreground mask, which is a binary image where foreground pixels have the value of 1, and background pixels have the value of 0. See the example on vision.ForegroundDetector doc page.
