METHODS AND APPARATUS FOR FILTER PARAMETER DETERMINATION AND SELECTION RESPONSIVE TO VARIABLE TRANSFORMS IN SPARSITY BASED DE-ARTIFACT FILTERING

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for filter parameter determination and selection responsive to variable transforms in sparsity-based de-artifact filtering.;SOLUTION: An apparatus includes a video encoder 100 for encoding picture data for at least a portion of a picture. The encoder 100 includes a sparsity-based de-artifact filter 165 for performing sparsity-based de-artifact filtering on the portion. One or more filter parameters for the sparsity-based de-artifact filtering are determined and selected in response to variable transforms.;COPYRIGHT: (C)2015,JPO&INPIT
