CODING DISTORTION REMOVAL METHOD, VIDEO ENCODING METHOD, VIDEO DECODING METHOD, AND APPARATUS AND PROGRAM FOR THE SAME

摘要

Mosaic-shaped block noise occurs when a compressed video signal is reproduced. This block noise is removed, but removing block noise from every block using a deblocking filter imposes a significant load on the deblocking filter. This load is therefore reduced by determining whether coding distortion removal (deblocking) is necessary, and applying a deblocking filter only when needed.
