An image compositing and compression method (Fig. 6) utilizes the creation and processing of parallax differences in motion photography. A parallax scanning MOE lens creates discrete parallax differences in the objects in the recorded scene that are perceived by the viewer as enhanced texture and depth when displayed. Using parallax differences in a captured scene a computer can , detect objects for the purpose of creating image compositing mattes.
