Title:
MOTION PREDICTION-BASED IMAGE CODING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/256329
Kind Code:
A1
Abstract:
A decoding method performed by a decoding device according to the present document includes: a step for acquiring adaptive motion vector resolution (AMVR)-related information from a bitstream; a step for deriving motion information about the current block on the basis of the AMVR-related information and motion information about surrounding blocks of the current block; a step for generating prediction samples of the current block on the basis of the motion information about the current block by using an interpolation filter; and a step for generating a recovery picture on the basis of the prediction samples. Here, the AMVR-related information may include information indicating that a 1/2 sample unit motion vector difference (MVD) precision is used for the current block.
