how to make decisions and selection of filter parameters, depending on the variable conversion in the sparsity-based artifact removal filtering and equipment

摘要

Method and apparatus for selecting and determining a filter parameter according to the variable conversion in artifact removal filtering sparsity base is provided. The apparatus includes a (100) encoder for encoding the picture data of at least part of the picture. Encoder (100), including the (165) artifact removal filter of sparsity-based to perform artifact removal filtering for sparsity-based for this part. Filter one or more parameters for artifact removal filtering sparsity base is selected and determined according to the variable conversion.
