A Deblocking Algorithm Based on HVS
一种基于人类视觉系统的去块效应算法

A major drawback related to the Block-based Discrete Cosine Transform(BDCT)for image and video compression is that the decoded images,especially at very low bit rates,exhibit highly noticeable blocking artifact near the block boundaries.In this paper,a deblocking algorithm based on Human Visual System(HVS)is proposed.For smooth regions,one dimension DCT domains filter is applied to reduce the blocking artifacts,but for texture regions a spatial filter is used.The experimental results show that the proposed algorithm reduces the blocking artifacts effectively and preserves the original edges faithfully.
