Abstract
Implementations of the invention are provided in methods for filter-unit based in-loop filtering in a video decoder and encoder. In one implementation, filter parameters are selected from a filter parameter set for each filter based on a filter index. In another implementation, the picture is partitioned into filter units according to filter unit size, which can be selected between a default size and other size. When other size is selected, the filter unit size may be conveyed using direct size information or ratio information. In another implementation, a merge flag and a merge index are used to convey filter unit merge information. A method for filter-unit based in-loop filtering in a video encoder for color video is disclosed. In one embodiment, the method incorporates filter syntax in the video bitstream by interleaving the color-component filter syntax for the FUs.
