Title:
AFFINE MOTION PREDICTION-BASED IMAGE DECODING METHOD AND APPARATUS USING AFFINE MVP CANDIDATE LIST IN IMAGE CODING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/055107
Kind Code:
A1
Abstract:
A method by which a decoding apparatus performs image decoding, according to the present document, comprises the steps of: obtaining motion prediction information about a current block from a bitstream; generating an affine MVP candidate list for the current block; deriving CPMVPs for CPs of the current block on the basis of the affine MVP candidate list; deriving CPMVDs for the CPs of the current block on the basis of the motion prediction information; deriving CPMVs for the CPs of the current block on the basis of the CPMVPs and the CPMVDs; and deriving prediction samples for the current block on the basis of the CPMVs.
