Abstract
Methods and apparatus are provided for collaborative partition coding for region based filters. An apparatus includes a video encoder (100) for encoding image data for a plurality of regions in a picture. The video encoder (100) includes multiple filters for filtering the image data based on region partition information for the plurality of regions. The region partition information for the plurality of regions is shared between the multiple filters.
Claims20
An apparatus for encoding video, comprising:
- a video encoder for encoding image data for a plurality of regions in a picture, including filtering the image data by multiple filters based on region partition information for the plurality of regions, the region partition information corresponding to partition blocks of arbitrary shapes,
- wherein region partition information and filter parameters are signaled in syntax for a plurality of regions in a picture, wherein a syntax element indicates region partition information that is shared by at least two but less than all of the multiple filters;
- and,
- wherein a different filter and different filtering parameters can be used for each partition of a picture and wherein the multiple filters are used for different functions.
In a video encoder, a method for encoding video, comprising:
- encoding image data for a plurality of regions in a picture, including filtering the image data by multiple filters based on region partition information for the plurality of regions, the region partition information corresponding to partition blocks of arbitrary shapes,
- wherein region partition information and filter parameters are signaled in syntax for a plurality of regions in a picture, wherein a syntax element indicates region partition information that is shared by at least two but less than all of the multiple filters;
- and,
- wherein a different filter and different filtering parameters can be used for each partition of a picture and wherein the multiple filters are used for different functions.
An apparatus for decoding video, comprising:
- a video decoder for determining region partition information and filter parameters from syntax for a plurality of regions in a picture, wherein a syntax element indicates region partition information that is shared by at least two but less than all of multiple filters;
- and
- decoding image data for the plurality of regions in a picture, including filtering the image data by the multiple filters based on the region partition information for the plurality of regions, the region partition information corresponding to partition blocks of arbitrary shapes, and
- wherein a different filter and different filtering parameters can be used for each partition of a picture and wherein the multiple filters are used for different functions.
In a video decoder, a method for decoding video, comprising:
- determining region partition information and filter parameters from syntax for a plurality of regions in a picture, wherein a syntax element indicates region partition information that is shared by at least two but less than all of multiple filters;
- and
- decoding image data for the plurality of regions in a picture, including filtering the image data by one or more of the multiple filters based on the region partition information for the plurality of regions, the region partition information corresponding to partition blocks of arbitrary shapes, and
- wherein a different filter and different filtering parameters can be used for each partition of a picture and wherein the multiple filters are used for different functions.
