<P>PROBLEM TO BE SOLVED: To provide a method of predicting motion vectors in a multi-layer video decoding process. <P>SOLUTION: The method comprises: scaling a base layer pixelblock partition map according to a size difference between recovered video data obtained by a base layer decode process and recovered video data obtained from an enhancement layer decode process; determining which base layer pixelblocks are co-located with the enhancement layer pixelblock; scaling motion vectors of the co-located base layer pixelblocks according to the size difference; averaging the scaled motion vectors of the co-located base layer pixelblocks while weighting contribution of each scaled motion vector according to a degree of overlap between the enhancement layer pixelblock and the scaled base layer pixelblock; and predicting a motion vector of an enhancement layer pixelblock. <P>COPYRIGHT: (C)2013,JPO&INPIT |
