Commonly the amplitudes of the noise patterns are made dependent on the local image content as so trade-off the perceptual image degradation due to the noise and the robustness of the embedded information against image processing-based attacks.
More recent approaches use salient geometric image properties such as isolated corner points or the correspondence map between domain and range blocks in fractal compression algorithm, to embed the watermark.
However, fordecreasing increasingly more (high to middle frequency DCT coefficients have to be removed upon embedding of the watermark, which leads to an increasing probability for artifacts to become visible due to the presence of the watermark.
the DCT coefficients can easily be forced to zero without re-encoding the bit stream by shifting the end of block marker (EOB) of DCT blocks in one of the two lc-subregions toward the DC-coefficient upto the selected cutoff index

常见的振幅噪音模式是依赖于当地形象的内容，使贸易小康感性形象退化由于噪音和稳健的嵌入式资料，对图像处理技术为基础的攻击。
较近期的办法，用鲜明的图象的几何特性，如孤立的角点或函授地图之间域和值域块分形压缩算法，嵌入水印。
不过， fordecreasing越来越多（高，以中频DCT系数都必须得到消除后，嵌入的水印，从而导致越来越多的概率为文物，成为看得见，由于在场的水印。
该DCT系数，可以很容易被强迫为零，没有重新编码位流，将结束块标记（竹叶黄酮）的DCT座，其中的两个LC -分地区对直流系数直到选定防渗墙指数
楼主太抠门了，这么老长的英文专业文只悬赏10分，强烈呼吁所有同志都不要帮他
