TRANSLATIONAL AND AFFINE CANDIDATES IN A UNIFIED LIST

摘要

At least a method and an apparatus are presented for efficiently encoding or decoding video. For example, one or more prediction models are determined respectively for one or more prediction candidates used for the video encoding based on one or more control point motion vectors of a current block of the video being encoded or decoded. It is determined from the one or more control point motion vectors that a first prediction model of the one or more prediction models may be a translational prediction model. It is also determined from the one or more control point motion vectors that a second prediction model of the one or more prediction models is to be an affine prediction model. The video is encoded or decoded based on a candidate list comprising the one or more prediction candidates determined respectively from the one or more prediction models.
