At the same time, the algorithm is combined with the video compressing standards, and embeds the information in the coefficient of the sub-low frequency in DCT domain, which improves the robustness.───同时算法与视频压缩算法相结合,在DCT域的次低频系数中嵌入信息,提高其鲁棒性。
At last, the adaptive vector quantization coding based on the DCT spectrum main orientation mentioned above is developed.───最后本文探讨了一种将基于结构特征的自适应分块与矢量量化相结合的编码方法。
Results show that the proposed scheme outperforms the standard DCT, especially at very low bit rates.───结果表明,提出的方案优于DCT标准,特别是在非常低码率的情况下。
