Claim 14:
15. 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;
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;
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 determined from one or more high level syntax elements or one or more region level syntax elements, or are inferred 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.
