摘要
Methods and apparatus are provided for sparsity-based de-artifact filtering for video encoding and decoding. An apparatus includes an encoder (400) for encoding at least a portion of an image by grouping regions within the portion based on a grouping metric, transforming the grouped regions, adaptively performing de-artifact filtering on the transformed regions using a de-artifacting filter (413) included in the encoder, inverse transforming the de-artifacted regions to create replacement regions, and restoring the replacement regions to positions with the image from which the regions were taken prior to the grouping.
