Claim:
1. 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 is only coded for one filter for the plurality of regions but is shared, and not separately coded, using signaling to allow a corresponding decoder to select a particular set of region partition information and filter parameters, by at least one other of the multiple filters while at least one other of the multiple filters separately determines the region partition information to be used thereby, rate-distortion cost and wherein different filters of the multiple filters can set filtering parameters for a region and wherein the partition information is decided by jointly considering parameter adaptation based on coding information and picture content.
