摘要

针对3D-HEVC 中深度图编码采用的视点合成失真优化方法的高复杂度问题，提出一种基于纹理平滑度的快速算法。首先结合帧内DC预测特性和统计学方法分析平坦纹理图中像素规律并设定基于纹理图平坦度的跳过准则；然后在深度图编码采用视点合成失真优化方法时提前分离出纹理图平坦区域所对应的深度图区域，并终止该区域像素基于虚拟视点合成的视点合成失真计算过程。实验结果证明该算法的有效性，能在保持编码质量的同时减少大量编码时间。

Abstract

A fast algorithm was proposed in order to reduce the v ew synthesis optimization (VSO) process in depth cod-ing for 3D-HEVC based on texture map smoothness.With the coding nformation derived from texture video sequences

the pixel regularity of smooth texture region was analyzed to set the skip rule using the properties of intra DC prediction and statistical methods.Then the depth regions corres to the flat texture map regions could be extracted and the VSO process of pixels belonging to this type of depth could be skipped.Experimental results show the effective-ness of the proposed algorithm.
