摘要

引入感知因素的RDO算法和感知编码可以提高编码视频主观质量，但也产生了明显的率失真性能损失。针对上述问题，提出了一种基于显著特征的 RDO 方法。首先探索了 HEVC 编码树单元的码率分布和显著特征之间的相关性，提出显著码率先验模型并确定了模型的初始参数；然后建立了码率差异最小化的率失真代价模型，并根据该模型推导得到自适应拉格朗日乘子计算方法；最后设计了模型参数更新规则。实验结果表明，算法在率失真性能基本不变的情况下，提高了视频的主观质量。

Abstract

Although the perception based rate distortion optimization (RDO) and coding algorithms can improve subjective quality

they significantly decrease rate distortion performance.For the above questions

a saliency-based RDO method was proposed.Firstly

according to the relation between rate distribution and saliency features of coding tree unit in HEVC

a priori saliency-rate model was designed.Furthermore

the initial parameters of the model were determined.Secondly

the rate difference minimization rate distortion model was proposed

and then a calculation method of the adaptive Lagrangian multiplier was derived from the model.Finally

update mechanism of model parameters was designed.Experimental results show that the proposed algorithm can improve the subjective quality while it maintains rate distortion performance.
