Title:
AN ENCODER, A DECODER AND CORRESPONDING METHODS FOR INTER PREDICTION
Document Type and Number:
WIPO Patent Application WO/2020/173196
Kind Code:
A1
Abstract:
An inter prediction method, comprising: obtaining an initial motion vector for a current block; determining search space positions according to the initial motion vector; checking matching costs of the search space positions according to a checking order to select a target search space position with a minimal matching cost; and determining a refining motion vector of the current block based on the initial motion vector and the target search space position, wherein a central search space position is checked first according to the checking order, and wherein the central search space position is pointed to by the initial motion vector.
