Abstract
A system and method for detecting the precise location of a reflective element in a video field wherein the determined location is subsequently utilized to generate a graphic to be added to a foreground video scene utilizing compositing techniques. A signal is generated specifying a precise point in the foreground video scene identifying a position of a reflective element. The signal is derived by comparing objects within the video field with a user specified size, shape and color. Graphics can be repositioned or lines or other graphic elements can be generated which track the movement of the reflective element.
