摘要
随机访问性能是评价多视点视频编码预测结构性能的一个重要指标,往往通过计算解码路径的复杂度来衡量,该文提出一种编码端和解码端联合计算的方法,通过对视频序列实际编码情况的统计来更新解码时的参考图像列表,进而获取更准确的参考帧信息.实验结果表明,所提出的方法能准确地计算出所需的参考帧,且参考帧数量比现有方法更少,能有效提高随机访问性能.
Random-access performance is an important requirement for the evaluation of MVC prediction structure.When random access happens,the system must be able to correctly calculate the decoding path.To calculate the decoding path,previous studies were mainly concentrated in decoder.In this paper we propose a new method for decode path calculation based on a reference frame list.The list is updated according to the actual encoding information.Experimental results show that this method can accurately calculate the needed frame.Moreover,the method can minimize the number of reference frame and improve the random access performance.
