What you are looking for is background subtraction. It is not really as simple as taking the difference between the two images. If you have a video taken with a stationary camera, then you can detect moving objects using the vision.ForegroundDetector object from the Computer Vision System Toolbox. See the Motion-based Multiple Object Tracking Example for more information.
