| 摘 要： | 将基于直方图对的无损数据隐藏用于立体图像编码,把数据隐藏和3D电视两个前沿研究结合起来.立体图像对中的一幅压缩后,无损嵌入另一幅中,使得3D电视的传输和存储容量减少一半,同时提供3D与2D电视兼容的可能.利用左右图的相关性进行4个参数的最优搜索,取得新的压缩极限.采用多循环方法的直方图对无损数据隐藏,得到较大容量以及较好的图像质量的无损嵌入.

| Abstract: | This paper uses reversible data hiding based on histogram-pair for stereo image coding,combines two cutting edge researches-data hiding and 3D TV.One frame of the stereo image pair is compressed and embedded into the other frame losslessly,the bandwidth and storage are halved,meanwhile,the possibility of compatibility of 3D and 2D TV is provided.The dependency of the two frames is utilized for optimal search of four parameters,new compression limitation is reached.Lossless embedding of higher capacity and better image quality is completed by histogram-pair reversible data hiding which adopts multi-cycle method. |
