Title: IN-LOOP POST FILTERING FOR VIDEO ENCODING AND DECODING
Abstract:
The present invention relates to an enhanced in-loop filter for an encoding or decoding process. According to an aspect of the invention, there is provided method of post filtering video data in an encoding and/or decoding process using hierarchical algorithms, the method comprising steps of: receiving one or more input pictures of video data; transforming, using one or more hierarchical algorithms, the one or more input pictures of video data to one or more pictures of transformed video data; and outputting the one or more transformed pictures of video data; wherein the transformed pictures of video data are enhanced for use within the encoding and/or decoding loop and wherein the method is performed in-loop within the encoding and/or decoding process.
