Abstract:
1. A system, comprising: a plurality of sub-sampling circuits, a plurality of smoothing filters, and a plurality of search circuits, wherein: each of said plurality of sub-sampling circuits is operable to generate based on an input video data, an output video data with lower resolution by applying a particular sub-sampling rate; said plurality of sub-sampling circuits are connected in sequence to generate a plurality of sub-sampled copies of an original picture, wherein said input video data corresponds to said original picture at a first one of said sub-sampling circuits and to said output video data of a previous sub-sampling circuit at each subsequent one of said sub-sampling circuits; each of said plurality of smoothing filters is operable to remove or reduce spurious motion vectors; and each of said plurality of search circuits is operable to determine motion estimation for an input picture, said input picture corresponds to said original picture at a last one of said plurality of search circuits and to one of said plurality of sub-sampled copies at each preceding one of said search circuits, wherein for said determination of said motion estimation, one or more of said plurality of search circuits are operable to:
