Abstract
Image encoding and decoding methods, apparatuses and computer-readable media are described. An example decoding method include: determining a first decoded unit from two decoded units on a left side of a to-be-decoded unit and a second decoded unit from three decoded units above the to-be-decoded unit; calculating first and second motion vector predictors (MVPs) of M control points of the to-be-decoded unit based on motion vectors of control points of the first and the second decoded units, respectively; generating a first and a second motion vector group based on the first and the second MVPs of the M control points, respectively; determining a target motion vector group from motion vector groups comprising the first motion vector group and the second motion vector group; and predicting the to-be-decoded unit based on the target motion vector group.
