Title:
MOTION REFINEMENT AND WEIGHTED PREDICTION
Document Type and Number:
WIPO Patent Application WO/2020/185147
Kind Code:
A9
Abstract:
A method for determining a prediction block for decoding or encoding a current block in a current picture of a video stream. The method includes obtaining a pair of initial motion vectors, the pair of initial motion vectors comprising a first initial motion vector and a second initial motion vector. The method also includes determining whether or not to refine the initial motion vectors. The method further includes refining the initial motion vectors as a result of determining to refine the initial motion vectors. The step of determining whether or not to refine the initial motion vectors comprises: i) determining whether a first prediction scheme and/or a second prediction scheme is enabled and ii) determining to refrain from refining the initial motion vectors as a result of determining that either the first prediction scheme or second prediction scheme is enabled or determining to refine the initial motion vectors as a result of determining neither the first prediction scheme nor second prediction scheme is enabled.
