Abstract
Embodiments of the disclosure provide a solution for video processing. A method for video processing is proposed. The method includes: obtaining, for a conversion between a target frame of a point cloud sequence and a bitstream of the point cloud sequence, a predicted value of the target frame by performing at least one of: alternating current (AC) prediction or direct current (DC) prediction in a domain; and performing the conversion based on the predicted value.
Claims20
A method of video processing, comprising:
- obtaining, for a conversion between a target frame of a point cloud sequence and a bitstream of the point cloud sequence, a predicted value of the target frame by performing at least one of:
- alternating current (AC) prediction or direct current (DC) prediction in a domain;
- and
- performing the conversion based on the predicted value.
An apparatus for video processing comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to perform a method comprising:
- obtaining, for a conversion between a target frame of a point cloud sequence and a bitstream of the point cloud sequence, a predicted value of the target frame by performing at least one of:
- alternating current (AC) prediction or direct current (DC) prediction in a domain;
- and
- performing the conversion based on the predicted value.
A non-transitory computer-readable storage medium storing instructions that cause a processor to perform a method comprising:
- obtaining, for a conversion between a target frame of a point cloud sequence and a bitstream of the point cloud sequence, a predicted value of the target frame by performing at least one of:
- alternating current (AC) prediction or direct current (DC) prediction in a domain;
- and
- performing the conversion based on the predicted value.
A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by an apparatus for video processing, wherein the method comprises:
- obtaining a predicted value of a target frame of a point cloud sequence by performing at least one of:
- alternating current (AC) prediction or direct current (DC) prediction in a domain;
- and
- generating the bitstream based on the predicted value.
