摘要: 针对分布式视频编码中的突发差错特性,提出一种基于混沌置乱预处理的方法。该方法通过混沌映射置乱图像,把差错均匀地分布在置乱后的图像中,结合传统分布式编码方法有效实现视频数据的编码。实验结果表明,混沌置乱预处理能够提高分布式视频编码的性能,实现复杂度低,可以应用于某些具有安全要求的领域。

Abstract: Chaotic permutation-based preprocessing is proposed to solve the burst error problem in video distributed coding, which uses the chaotic mapping to permute the image for scattering the error. After preprocessing, the traditional distributed video coding with permutation preprocessing can implement video coding efficiently. Experimental results show that permutation-based preprocessing can improve the performance of distributed video coding, and it has low-complexity and can be applied in some security fields.

Key words: distributed video coding, multimedia system, chaotic permutation
