摘要 运用随机图论、超空间等方法,首先提出了针对编码预测结构的随机访问性能评价函数,对解码端和服务器端的随机访问支持代价进行评价.进而根据实际应用中的带宽、交互限制等多种目标建立了编码策略评价的多目标非线性数学模型,对编码策略在多种性能参数约束条件下如何实现最优策略进行了讨论.利用该非线性多目标规划模型对多视点视频编码策略进行了优化设计,可以获得较好的随机访问性能. In this paper, evaluation function of MVC （multiview video coding） random accessibility for decoder and server is first proposed based on the methods from random graph theory and hyper-space. Furthermore, a non-linear multi-purpose programming model for MVC performance evaluation is also proposed according to the constraints from practical network bandwidth, restrictions of interaction and other problems. Based on this model, optimal coding strategies for different MVC schemes under variant performance constraints are discussed. It is found that random accessibility of MVC scheme can be improved via this non-linear multi-purpose programming model.
