基于HVS及偏微分方程的去块效应算法

An HVS and Partial Differential Equations Based Image Deblocking Algorithm

提出一种新的去块效应算法.该算法结合P-M扩散与相干增强扩散各自的优点去除块效应,并在此基础上考虑了人类视觉系统特性在去块效应方面的作用.实验结果表明:该算法既能够有效去除块效应,又能很好地保护图像的边缘信息.

An new deblocking algorithm was proposed. This algorithm based on HVS, which builds a weight model combining coherence diffusion and P-M diffusion. The experimental results show that the proposed algorithm reduces the blocking artifacts effectively and preserves the original edges.
