METHOD AND APPARATUS FOR DETERMINING THE LOCATION OF A REFLECTIVE OBJECT WITHIN A VIDEO FIELD |
摘要 |
A system and method for detecting (11) 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 (13) utilizing compositing techniques (21). A signal is generated specifying a precise point in the foreground video scene (13) 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. |
