Title:

IMAGE ENCODING/DECODING METHOD AND APPARATUS, AND RECORDING MEDIUM STORING BITSTREAM

Document Type and Number:

WIPO Patent Application WO/2023/055149

Kind Code:

A1

Abstract:

An image decoding/encoding method and apparatus according to the present disclosure may: generate a candidate list for predicting a first motion vector of a current block; derive a control point vector of the current block on the basis of a candidate index of the current block and the candidate list; correct the control point vector of the current block on the basis of a predetermined delta motion vector; derive the first motion vector of the current block on the basis of the corrected control point vector; and perform inter prediction on the current block by using the first motion vector of the current block.
