The system utilizes a model of the background space to change the video stream so as to include the image at some location within the background space. It includes a video frame grabber and an image implantation system. The frame grabber grabs a single frame of the video signal at one time. The image implantation system typically implants the grabbed image into the frame onto a predefined portion of a preselected one of the surfaces of the background space if the portion is shown in the frame. To determine the location of the portion to have implantation, the image implantation system includes a unit for receiving a) a flat model of the fixed surfaces and b) an image mask indicating the portion of the flat model onto which the image is to be mixed. Via the model, the image implantation system identifies if and where the portion is shown in the frame.Other References
