OBJECT TRACKING USING GRAPHICS ENGINE DERIVED VECTORS IN A MOTION ESTIMATION SYSTEM
摘要
A method and apparatus are provided for motion estimation in a sequence of images. One or more motion vectors representing movement of a camera or viewer position or direction are determined between each pair of fields or frames in the sequence of images. A set of candidate motion vectors is then determined for deriving positions of objects in a field or frame from the positions of objects in a previous field or frame. This set of candidate motion vectors is adjusted using the motion vectors representing movement of camera or viewer position and thus a set of motion vectors is derived for a sequence of images using the adjusted set of candidate motion vectors.
