摘要:

在分析现有视频信息隐藏算法的基础上,结合 H.264/AVC 视频低频域系数的特征,提出一种基于H.264/AVC低频域视频信息隐藏算法。在量化后的离散余弦变换(DCT,discrete cosine transform)块低频区中,选取3 个绝对值最大的非零系数,用改进的矩阵编码的方法嵌入信息。实验结果表明,该算法能够实现实时嵌入和提取信息,信息嵌入容量大,嵌入效率高,对视频质量影响较小等特点。

Abstract:

On the basis of analyzing some existing video data hiding algorithms and combining it with the features of H.264/AVC video low frequency coefficients,a new data hiding algorithm based on H.264/AVC low frequency domain was proposed.After quantification of DCT blocks in the low frequency area,three maximum absolute value of the nonzero coefficients were selected and information was embedded with an improved matrix encoding method.Simulation results show that the proposed algorithm can realize real-time embedding and extracting information,great capacity of embedding information,embedded high efficiency and less influence on video quality etc.
