摘要： Methods and apparatus for a classification-based loop filter are provided. An encoding method encodes an input picture by transforming and quantizing a residue of the input picture to obtain quantized transform coefficients. Then inverse quantizing and inverse transforming the quantized transform coefficients to obtain a reconstructed version of the residue. A reconstructed version of the input picture is obtained by combining at least one reference picture with the reconstructed version of the residue. Pixels in the reconstructed version of the input picture are classified within a respective one of a plurality of categories responsive to local geometric characteristics. Pixels are selected for filtering responsive to a corresponding classification of the pixels with respect to the plurality of categories.
