Abstract
A method for coding video data implemented by a video coding apparatus. The method includes filtering padding samples within an extended area disposed around a video unit, and converting between the video unit of the video and a bitstream in accordance with the one or more padding samples in the extended area as filtered.
Claims20
A method for processing video data, comprising:
- generating, during a conversion between a first block of a video and a bitstream of the video, padding samples in an extended area of a first picture, wherein a prediction block of the first block is derived from the first picture;
- filtering the padding samples within the extended area;
- and
- performing the conversion based on the padding samples in the extended area as filtered.
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:
- generate, during a conversion between a first block of a video and a bitstream of the video, padding samples in an extended area of a first picture, wherein a prediction block of the first block is derived from the first picture;
- filter the padding samples within the extended area;
- and
- perform the conversion based on the padding samples in the extended area as filtered.
A non-transitory computer-readable storage medium storing instructions that cause a processor to:
- generate, during a conversion between a first block of a video and a bitstream of the video, padding samples in an extended area of a first picture, wherein a prediction block of the first block is derived from the first picture;
- filter the padding samples within the extended area;
- and
- perform the conversion based on the padding samples in the extended area as filtered.
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:
- generating, for a first block of the video, padding samples in an extended area of a first picture, wherein a prediction block of the first block is derived from the first picture;
- filtering the padding samples within the extended area;
- and
- generating the bitstream of the video based on the padding samples in the extended area as filtered.
