Abstract
A method of video processing is described. The method includes determining, for a conversion between a current video block of a video and a bitstream representation of the video, an applicability of a geometric partitioning mode based on a rule; and performing the conversion based on the determining, and wherein the rule depends on a block width, a block height, and/or an aspect ratio of the current video block.
Claims19
A method of processing video data, comprising:
- determining whether to enable a geometric partitioning mode for a current video block at least based on a first syntax element indicative of an application of a combined inter-picture merge and intra-picture prediction mode and a second syntax element indicative of an application of a regular merge mode;
- and
- performing a conversion between the current video block of a video and a bitstream of the video,
- wherein a geometric partitioning mode index for the current video block is coded in the bitstream and a binarization of the geometric partitioning mode index is performed according to a rule,
- wherein the geometric partitioning mode index specifies a geometric splitting shape of the geometric partitioning mode applied to the current video block,
- wherein the rule specifies that the geometric partitioning mode index is coded with a fixed-length binarization.
An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- determine whether to enable a geometric partitioning mode for a current video block at least based on a first syntax element indicative of an application of a combined inter-picture merge and intra-picture prediction mode and a second syntax element indicative of an application of a regular merge mode;
- and
- perform a conversion between the current video block of a video and a bitstream of the video,
- wherein a geometric partitioning mode index for the current video block is coded in the bitstream and a binarization of the geometric partitioning mode index is performed according to a rule,
- wherein the geometric partitioning mode index specifies a geometric splitting shape of the geometric partitioning mode applied to the current video block,
- wherein the rule specifies that the geometric partitioning mode index is coded with a fixed-length binarization.
A non-transitory computer-readable storage medium storing instructions that cause a processor to:
- determine whether to enable a geometric partitioning mode for a current video block at least based on a first syntax element indicative of application of a combined inter-picture merge and intra-picture prediction mode and a second syntax element indicative of application of a regular merge mode;
- and
- perform a conversion between the current video block of a video and a bitstream of the video,
- wherein a geometric partitioning mode index for the current video block is coded in the bitstream and a binarization of the geometric partitioning mode index is performed according to a rule,
- wherein the geometric partitioning mode index specifies a geometric splitting shape of the geometric partitioning mode applied to the current video block,
- wherein the rule specifies that the geometric partitioning mode index is coded with a fixed-length binarization.
A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:
- determining whether to enable a geometric partitioning mode for a current video block at least based on a first syntax element indicative of application of a combined inter-picture merge and intra-picture prediction mode and a second syntax element indicative of application of a regular merge mode;
- and
- generating the bitstream for the current video block of the video,
- wherein a geometric partitioning mode index for the current video block is coded in the bitstream and a binarization of the geometric partitioning mode index is performed according to a rule,
- wherein the geometric partitioning mode index specifies a geometric splitting shape of the geometric partitioning mode applied to the current video block,
- wherein the rule specifies that the geometric partitioning mode index is coded with a fixed-length binarization.
