大家帮帮忙,非常感谢。 We investigate the problem of embedding data in raw video sequences with minimum video mean-square distortion for any required data recovery error rate. In particular, for any given video frame sequence and any (block) transform domain of interest, we find the optimal carrier and scalar parametrized linear operator on the video data that maximize the output signalto-interference-plus-noise ratio (SINR) of the maximum-SINR data receiver filter or, equivalently, minimize the average embedding distortion for any target message extraction error rate.The procedure is extended from single-carrier to multi-carrier(multiple messages) embedding. As a practical consideration,a sub-optimal computationally efficient embedding algorithm is also proposed. |

| 我们核查了,具有最小视频均方失真序列的原始影像中的数据嵌入问题,用以查明任何所需数据恢复的误差率。尤其是,对于一些视频帧序列和一些兴趣的变换域,我们在视频数据中,找到了最优载体和标量的参数化线性算子,从而将数据接收滤波器的输出信号干扰噪声比最大化,或者,同样的,将平均嵌入失真最小化,以获得目标信息提取错误率。此过程从单载体植入发展到多载体植入 (多信息),作为一种现实考量,次优计算机有效嵌入法也应运而生。 |

Extensive experimental results demonstrate that sub-optimal embedding as described has video distortion versus data extraction error rate performance comparable to optimal embedding. Our studies also demonstrate the robustness of the optimal (and sub-optimal) embedding schemes to H.264 compliant encoding.麻烦再帮翻译这个,谢谢 |
