Blocking effect reduction in low bitrate video on a mobile platform

Abstract

The paper presents a new algorithm for blocking artifacts reduction in low bit rate video. The algorithm addresses the blocking effect on block boundaries, as well as the one inside the blocks. The algorithm works with variety of coding schemes, and does not exploit any information from the coded bitstream. It has extremely low complexity and it is designed to work on a mobile platform in real time. It incorporates two parts: artifacts detection procedure, which decides whether the processing is required for the particular location in the video frame, and artifacts reduction procedure, which performs the actual filtering depending on local image characteristics. The experiments confirm the algorithms effectiveness, as well as its low computational complexity.
