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.Using reversible data hiding based on histogrampair for stereo image coding, two cutting edge researches-data hiding and 3D TV were combined. One frame of the stereo image pair was compressed and embedded into the other frame without any loss, and the bandwidth and storage were halved, providing the possibility of compatibility of 3D and 2D TV. The dependency of the two frames was utilized for optimal search of four parameters, and the new compression limitation was achived. Lossless embedding of higher capacity and better image quality was completed by histogram-pair reversible data hiding which adopts the multi- cycle method.
