INTER PREDICTION-BASED IMAGE CODING METHOD AND DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18231129 titled 'INTER PREDICTION-BASED IMAGE CODING METHOD AND DEVICE
Simplified Explanation
- The patent application describes an image decoding method. - The method involves deriving an inter prediction mode from encoded information. - Reference picture lists are constructed. - Motion information, including reference picture indices for symmetric motion vector differences (SMVD), is derived based on the reference pictures in the reference picture lists. - Prediction samples are generated based on the motion information. - The reference picture indices for SMVD are derived using short-term reference pictures included in the reference picture lists.
Original Abstract Submitted
An image decoding method according to the present document may comprise: a step for deriving an inter prediction mode from encoded information; a step for constructing reference pictures lists; a step for deriving motion information including reference picture indices for symmetric motion vector differences (SMVD) on the basis of reference pictures included in the reference picture lists; and a step for generating prediction samples on the basis of the motion information. The reference picture indices for SMVD may be derived on the basis of short-term reference pictures included in the reference picture lists.
