摘要

Block-based low bit rate video coding is the most widely used method for storage and communication. This method even though increases compression they yield visually annoying artifacts that has to be reduced while decoding the compressed video data. Several methods are proposed for this in the literature, but most of them are for still images and has high computational complexity. In this study, we propose a new blocking artifact reduction algorithm using interpolation. Where instead of block, the block boundaries are classified using a simple statistical property of the pixels along the boundary and adaptively interpolated to reduce the artifacts using a low computational procedure. The computer simulation results confirm the low computational complexity and better performance of the proposed method.
