Abstract
A computer-implemented method and apparatus for processing video signals representative of pixels of a current block of a current picture. According to a preferred embodiment, the current block is compared to a plurality of blocks of a previous picture to provide a plurality of corresponding motion vectors, wherein each motion vector corresponds to a respective motion estimation error measure. It is determined whether the current block contains at least one region of high spatial energy and at least one region of relatively low spatial energy associated with different motion vectors of the plurality of corresponding motion vectors. The block is encoded in accordance with this determination.
Claims18
A computer-implemented method for processing video signals representative of pixels of a current block of a current picture, the method comprising the steps of:
- (a) comparing the current block to a plurality of blocks of a previous picture to provide a plurality of corresponding motion vectors, wherein each motion vector corresponds to a respective motion estimation error measure;
- (b) determining whether the current block contains at least one region of high spatial energy and at least one region of relatively low spatial energy associated with different motion vectors of the plurality of corresponding motion vectors;
- and
- (c) encoding the block in accordance with the determination of step (b).
A computer-implemented apparatus for processing video signals representative of pixels of a current block of a current picture, the apparatus comprising:
- (a) means for comparing the current block to a plurality of blocks of a previous picture to provide a plurality of corresponding motion vectors, wherein each motion vector corresponds to a respective motion estimation error measure;
- (b) means for determining whether the current block contains at least one region of high spatial energy and at least one region of relatively low spatial energy associated with different motion vectors of the plurality of corresponding motion vectors;
- and
- (c) means for encoding the block in accordance with the determination of means (b).
