- METHODS AND APPARATUS FOR SPARSITY-BASED DE-ARTIFACT FILTERING FOR VIDEO ENCODING AND DECODING

摘要

Method and apparatus is provided for the de-artifact filtering based on rareness of Video coding and decoding. One device includes an encoder (400), it is used to encode at least part image, pass through being grouped in group areas within base thereof in metric system, convert the region of grouping, de-artifact filtering is suitably executed on transformed region using including de-artifact filter (413) in the encoder, the inverse transformation de-artifact region for creating replacement areas, makes replacement areas be restored to position with from it in the image that the forefoot area of grouping is taken.
