Abstract
Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for video decoding. In one method, a decoder determines a fusion scheme applied in decoder-side intra mode derivation (DIMD) mode and in template-based intra mode derivation (TIMD) mode, and the fusion scheme is applied as a weighted average of predictors in the DIMD mode and in the TIMD mode.
Claims20
A method for video decoding, comprising:
- determining, by a decoder, a fusion scheme applied in decoder-side intra mode derivation (DIMD) mode and template-based intra mode derivation (TIMD) mode, wherein the fusion scheme is applied as a weighted average of predictors in the DIMD mode and the TIMD mode.
An apparatus for video decoding, comprising:
- one or more processors;
- and
- a memory configured to store instructions executable by the one or more processors and a bitstream to be decoded;
- wherein the one or more processors, upon execution of the instructions, are configured to perform operations with the bitstream, the operations comprising:
- determining a fusion scheme applied in decoder-side intra mode derivation (DIMD) mode and template-based intra mode derivation (TIMD) mode, wherein the fusion scheme is applied as a weighted average of predictors in the DIMD mode and the TIMD mode.
A non-transitory computer-readable storage medium for video decoding storing computer-executable instructions and a bitstream to be decoded, when the computer-executable instructions executed by one or more computer processors, cause the one or more computer processors to perform operations with the bitstream, the operations comprising:
- determining a fusion scheme applied in decoder-side intra mode derivation (DIMD) mode and template-based intra mode derivation (TIMD) mode, wherein the fusion scheme is applied as a weighted average of predictors in the DIMD mode and the TIMD mode.
