去块滤波（DF）在提高图像和视频编码的视觉质量方面起着重要作用。设计良好的DF方案应该在编码效率和编码复杂度之间实现良好的折衷。多视点视频编码（MVC）的DF算法采用H. 264 DF方案来提高视频质量，但这导致了相对较高的编码复杂度。在本文中，我们提出了一种低复杂度的DF算法，考虑到视图的相关性，它利用视图的相关性跳过边界强度（BS）的计算的宏块（MB）的运动跳过模式编码。实验结果表明，与传统算法相比，该算法在不降低视觉质量的前提下，可以显著减少DF时间（35%~ 6%）。
Deblocking filtering (DF) plays a major role in improving the visual quality for image and video coding. A well-designed DF scheme should achieve a good tradeoff between coding efficiency and coding complexity. The DF algorithm for multiview video coding (MVC) has adopted H.264 DF scheme to improve the video quality, which, however, leads to relatively high coding complexity. In this paper, we propose a low complexity DF algorithm in consideration of view correlation, which exploits the view correlation to skip the boundary strength (BS) computation of macroblocks (MBs) that are coded in motion skip mode. Experimental results show that the proposed algorithm can dramatically reduce DF time (35%-6%) without degrading the visual quality in comparison to the conventional algorithm.
