Utility
Motion estimation
24 Aug 20
A technique of motion estimation in video compression is described, the technique including: determining, in one or more reference frames of a video picture, the best full-pixel motion vector F for a block in a current frame of the video picture, wherein m and n are signed numbers and integer multiples of the distance between two adjacent full-pixels; selecting the best half-pixel motion vector candidates from a set of half-pixel motion vectors based on the best full-pixel motion vector; determining the best half-pixel motion vector H; selecting the best quarter-pixel motion vector candidates from a set of quarter-pixel motion vectors based on the best full-pixel motion vector and the best half-pixel motion vector; determining the best quarter-pixel motion vector Q; and determining the best motion vector for the block as BMV.
