Abstract

A graphic image system comprising a video camera producing a first video signal defining a first image including a foreground object and a background, the foreground object preferably including an image of a human subject having a head with a face; an image position estimating system for identifying a position with respect to said foreground object, e.g., the head, the foreground object having features in constant physical relation to the position; and a computer, responsive to the position estimating system, for defining a mask region separating the foreground object from said background. The computer generates a second video signal including a portion corresponding to the mask region, responsive to said position estimating system, which preferably includes a character having a mask outline. In one embodiment, the mask region of the second video signal is keyed so that the foreground object of the first video signal shows through, with the second video signal having portions which interact with the foreground object. In another embodiment, means, responsive to the position estimating system, for dynamically defining an estimated boundary of the face and for merging the face, as limited by the estimated boundary, within the mask outline of the character. Video and still imaging devices may be flexibly placed in uncontrolled environments, such as in a kiosk in a retail store, with an actual facial image within the uncontrolled environment placed within a computer generated virtual world replacing the existing background and any non-participants.
