Object tracking to use the moment and acceleration vector in the motion estimation system

摘要

And apparatus for motion estimation method in a video image sequence is provided. Subdivided into a plurality of blocks of frames or fields of a) video image sequence, specifying each set of candidate motion vectors for each block in the frame or b) each video field, the method, or video field c) the current determining for each block of the frame, which of the candidate motion vectors, each of or cause the best match with the block of video fields or frames of the front, it has been determined in this manner d) for each block storing the candidate motion vectors derived from the best match vector at block position which is offset by a distance to form a motion vector field of a frame or video field current using the best matching vector derived from e) candidate motion vectors It includes forming a motion vector field by a further. In addition, I repeat not step a) with respect to the frame or video field following the video fields or frames to the current e). The set of candidate motion vectors to be specified in the block or frame following the video field, including the candidates stored in the block positioned between the frame or video field current in step e) in step b). This method makes it possible to improve the accuracy by introducing a motion vector candidate true motion estimator tile-based or block is derived from the physical behavior of real-world objects.
