摘　　要： 基于多视点视频序列相关性,提出独立片的概念,进而提出一种采用自适应参考帧模式选择的多视点视频编码方法.在保证高率失真性能的前提下,应用独立片、自适应算法有效地降低了多视点视频编码计算复杂度,将多种性能进行有机结合,可以根据用户外部设置的参数调整自适应模式.实验结果表明,该方法在保证高压缩效率的前提下,能有效地降低计算复杂度,并改善随机访问性能. Based on analysis on the correlations of multi-view video, the concept of independent slice is introduced, and a multiview video coding method with adaptive selection of reference frame modes is proposed. The introduction of independent slice and adaptive selection of reference frame modes greatly contribute to the increase of coding efficiency as well as the reduction of computational complexity of the method. In addition, the proposed method combines many MVC prediction schemes and is able to dynamically select suitable coding mode according to the user＇s decision. Experimental results show that the proposed multiview video coding method can effectively reduce the computational complexity and improve the random access performance while maintaining high coding efficiency.
