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.
Claims19
An apparatus, comprising:
- a video encoder for encoding image data for a plurality of regions in a picture, wherein said video encoder comprises multiple filters for filtering the image data based on region partition information for the plurality of regions, the multiple filters being used for different functions, and wherein the region partition information for the plurality of regions is shared by at least two of the multiple filters while at least one other of the multiple filters separately determines the region partition information to be used thereby.
In a video encoder, a method, comprising:
- encoding image data for a plurality of regions in a picture, wherein the image data is filtered by multiple filters based on region partition information for the plurality of regions, the multiple filters being used for different functions, and wherein the region partition information for the plurality of regions is shared by at least two of the multiple filters while at least one other of the multiple filters separately determines the region partition information to be used there by.
An apparatus, comprising:
- a video decoder for decoding image data for a plurality of regions in a picture, wherein said video decoder comprises multiple filters for filtering the image data based on region partition information for the plurality of regions, the multiple filters being used for different functions, and wherein the region partition information for the plurality of regions is shared by at least two of the multiple filters while at least one other of the multiple filters separately determines the region partition information to be used there by.
In a video decoder, a method, comprising:
- decoding image data for a plurality of regions in a picture, wherein the image data is filtered by multiple filters based on region partition information for the plurality of regions, the multiple filters being used for different functions, and wherein the region partition information for the plurality of regions is shared by at least two of the multiple filters while at least one other of the multiple filters separately determines the region partition information to be used there by.
