Abstract
An image processing system for removing and replacing the background portion of an image with a replacement background image. The image processing system receives an actual background image and a current image. The current image includes a foreground portion and a background portion. The background portion of the current image includes at least a portion of the actual background image. An image mask is generated representing the similarities and differences between the actual background image and the current image. A new image is generated in response to the image mask and contains portions of the current image and portions of the replacement background image.
