ABSTRACT:
Deblocking filters are disclosed, where the nature of the filter is determined based upon the level of detail of a reconstructed video frame in the region in which the block boundary is located. One embodiment of the method of the invention includes identifying a boundary between two blocks of the reconstructed video frame, determining the level of detail of the reconstructed video frame in a region in which the block boundary is located, wherein the region includes pixels from multiple rows and multiple columns of the reconstructed video frame and includes at least one pixel that is not immediately adjacent the block boundary and selecting a filter to apply to predetermined pixels on either side of the block boundary based upon the determined level of detail.
