Adaptive motion estimation coding

摘要

A method for encoding a video signal comprising a plurality of reference frames and non-reference frames includes: for a non-reference frame to be encoded, determining if at least a portion of a reference frame that is a backward reference frame of the non-reference frame has no scene change; and when the portion of the reference frame has no scene change, scaling down a search range for block matching of the portion of the non-reference frame.

1. A method for encoding a video signal comprising a plurality of reference frames, and non-reference frames, the method comprising:
analyzing motion vectors of at least a portion of a first reference frame only without analyzing motion vectors of non-reference frames, the first reference frame being a backward reference frame for a non-reference frame; when motion vector statistics of the motion vectors are less than or equal to a preset threshold, determining a reference frame that is close to the non-reference frame; and duplicating at least a portion of the determined reference frame as at least a portion of the non-reference frame.
