Abstract
Methods and apparatus are provided for adaptive coupled pre-processing and post-processing filters for video encoding and decoding. The apparatus and method encode input data for a picture into a resultant bitstream, wherein said video encoder comprises a pre-filter and a post-filter coupled to the pre-filter, wherein said pre-filter filters the input data for the picture and the post-filter filters in-loop reconstructed data for the picture.
