Methods and apparatus for uni-prediction of self-derivation of motion estimation

摘要

Methods and apparatus are provided for uni-prediction of self-derivation of motion estimation. An apparatus includes a video encoder for encoding at least a portion of a picture. The video encoder includes a self derivation motion estimator for performing self derivation motion estimation for the portion. The self derivation motion estimation is used for selectively performing uni-prediction or bi-prediction for the portion based on one or more criterion.

1. An apparatus, comprising:
a video encoder for encoding at least a portion of a picture, the video encoder comprising a self derivation motion estimator for performing self derivation motion estimation for the portion, wherein the self derivation motion estimator determines a first motion vector (“MV0”) between the picture and a forward reference picture and a second motion vector (“MV1”) between the picture and a backward reference picture; wherein the self derivation motion estimator further demonstrates a first difference between MV0 and a first motion vector predictor, where the first motion vector predictor is determined based on motion vectors of neighboring blocks, wherein the self derivation motion estimator further determines a second difference between MV1 and a second motion vector predictor, where the second motion vector predictor is determined based on motion vectors of neighboring blocks, wherein the self derivation motion estimator further selects bi-directional prediction among uni-directional prediction or bi-directional prediction for the portion of the picture based on a determination that the first difference is less than a threshold and the second difference is less than the threshold.
