Title:
METHOD AND APPARATUS FOR DERIVING INTERPOLATION FILTER INDEX FOR CURRENT BLOCK
Document Type and Number:
Japanese Patent JP2023169226
Kind Code:
A
Abstract:
To provide a method, encoder, decoder, program, and storage medium for inter prediction improving the quality of a prediction signal and the coding efficiency.SOLUTION: A method for inter prediction includes: constructing a history-based motion information (HMI) candidate list; adding one or more history-based motion information candidates from the history-based motion information candidate list into a motion information candidate list for the block; and deriving motion information for the block based on the motion information candidate list. A half-pixel interpolation filter index is inherited when the history-based motion information candidate list is used, and a dedicated interpolation filter is selected instead of a default interpolation filter.SELECTED DRAWING: Figure 14
