摘要：

提出一种新的分布式视频编码(DVC)算法,在编码端对原始视频帧进行块分类后,对其稀疏块进行编码;在解码端应用复杂的重构算法并结合DVC边信息融合算法。提出的算法具有复杂度低、码率较低、码率控制灵活等优点,同时编解码端互相独立、无须反馈通道。仿真实验表明,提出的算法具有降低编码复杂度和保持压缩效率的优点。

Abstract:

A new DVC algorithm for multi-view video coding was proposed in this paper.At the encoder,the blocks of original video frames were classified,and each frame was jointly decoded through finite iterations.Multi-view DVC side-information generation and CS reconstruction algorithm were integrated in the iterations.There were lots of advantages in CS-DVC framecork,such as low-complexity encoder,low bit-rate,and rate-control flexibility etc.This algorithm was consisted of independent encoder/decoder without any feed-back channels.This feature made the algorithm applicable to more extensive fields.The simulation results show that the proposed algorithm has low encoding complexity and can keep compression efficiehcy.
