Claim 2:
3. 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;
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; and, wherein at least one of the region partition information and filter parameters for the multiple filters are signaled using one or more high level syntax elements or one or more region level syntax elements, or are inferred by a corresponding decoder from at least one of previously coded regions, previously coded pictures, and previously coded video sequences, the picture corresponding to a currently coded video sequence.
