MOTION VECTOR PREDICTOR CANDIDATE CLIPPING REMOVAL FOR VIDEO CODING

摘要

This disclosure describes techniques for coding a video block based on an unclipped version of a motion vector predictor candidate. The techniques include determining a motion vector predictor candidate list including motion vector predictor candidates from neighboring video blocks without clipping the motion vector predictor candidates. More specifically, if one of the motion vector predictor candidates points to a prediction block located outside of a reference picture boundary relative to the current video block, the techniques allow an unclipped version of the motion vector predictor candidate to be included in the candidate list. The current video block is then coded based on a determined unclipped motion vector predictor candidate of the candidate list. Elimination of the motion vector predictor candidate clipping process reduces complexity at both the video encoder and the video decoder.
