PICTURE PREDICTION METHOD AND RELATED APPARATUS
First Claim
1. A picture prediction method, comprising:
- determining K1 pixel samples in a picture block x, and determining a candidate motion information unit set corresponding to each pixel sample in the K1 pixel samples, wherein the candidate motion information unit set corresponding to each pixel sample comprises at least one candidate motion information unit, and K1 is an integer that is greater than or equal to 2;
determining a merged motion information unit set i comprising K1 motion information units, whereineach motion information unit in the merged motion information unit set i is selected from at least a part of motion information units in candidate motion information unit sets corresponding to different pixel samples in the K1 pixel samples, and the motion information unit comprises a motion vector whose prediction direction is at least one of;
forward and backward; and
predicting a pixel value of the picture block x by using a non-translational motion model and the merged motion information unit set i.
