METHODS AND APPARATUS FOR IN-LOOP DE-ARTIFACTING FILTERING BASED ON MULTI-LATTICE SPARSITY-BASED FILTERING

摘要

There are provided methods and apparatus for in-loop de-artifact filtering based on multi-lattice sparsity-based filtering. An apparatus includes an encoder for encoding picture data for a picture. The encoder includes an in-loop de-artifacting filter for de-artifacting the picture data to output an adaptive weighted combination of at least two filtered versions of the picture. The picture data includes at least one sub-sampling of the picture.
