Abstract:
A method of video decoding for a decoder includes acquiring a current picture from a coded video bitstream. The method further includes selecting a first neighboring block from a plurality of neighboring blocks of a current block in the current picture. The method further includes determining, based on a motion vector predictor of the selected first neighboring block, a candidate block that is included in a previously decoded picture and that is one of (i) neighboring to a collocated block of the current block and (ii) within the collocated block. The method further includes performing temporal motion vector prediction for the current block based on a motion vector predictor of the candidate block.
