Abstract
An improved scheme for intra-inter prediction mode and an adaptive intra-inter prediction mode for video coding/decoding, including selecting a set of weightings in an intra-inter mode and applying position dependent intra prediction combination to modify at least one of an inter prediction sample and another sample.
Claims20
A method for video encoding, the method performed by at least one processor and comprising:
- selecting, based on whether an intra mode uses different initial weighting factors of position dependent intra prediction combination (PDPC) than PDPC, a set of weightings in an intra-inter mode;
- and
- applying PDPC to modify at least one of an inter prediction sample and another sample.
An apparatus for video encoding, the apparatus comprising:
- at least one memory configured to store computer program code;
- at least one hardware processor configured to access the computer program code and operate as instructed by the computer program code, the computer program code including:
- selecting code configured to cause the at least one processor to select, based on whether an intra mode uses different initial weighting factors of position dependent intra prediction combination (PDPC) than PDPC, a set of weightings in an intra-inter mode;
- and
- applying code configured to cause the at least one processor to apply PDPC to modify at least one of an inter prediction sample and another sample.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
- selecting, based on whether an intra mode uses different initial weighting factors of position dependent intra prediction combination (PDPC) than PDPC, a set of weightings in an intra-inter mode;
- and
- applying PDPC to modify at least one of an inter prediction sample and another sample.
