| 摘 要： | 视频编码率失真性能的研究一般没有考虑到能量对率失真(RD)性能的影响。本文针对WSNs节点如何分配计算能耗与传输能耗,使得视频信号RD性能最好的问题展开了研究。首先建立了压缩与传输部分的功耗-率-失真模型,并由此得到系统的功耗-率-失真模型。随后通过数值方法,分析了压缩功耗与系统失真之间关系。实验结果表明存在一个最优的压缩功耗PS值,使得系统的失真度最小。

| Abstract: | The influence of power to the RD performance for video coding is not considered traditionally. An optimal computing and transmitting power which results in a minimized rate distortion is considered in this paper. The energy distributed of WSNs node is optimized, the power-rate -distortion model is constructed, Based on this model, the power is integrated into the rate-distortion analyze frame. The experiment results show that the optimum compression power Ps makes the distortion of the system minimum. |
