| 4. | The arithmetic expressed in this text solved contradiction between the watermark ' s transparence and the arithmetic ' s maleness , using the inlaid watermark of that arithmetic having goodly transparence , and the result of the experiment shows the arithmetic has goodly maleness to jpeg compress , noise , low channel filter wave , mosaic , signal tone up , secondary watermark , cut and zoom , especially to sharpen , strengthen contrast , strengthen edge , equilibrium , and so on , signal strengthen can hardly effect to get away the watermark
实验表明，本文算法较好地解决了水印透明性与算法鲁棒性之间的矛盾，使用该算法嵌入的水印具有较好的透明性，同时本文算法对jpeg压缩、噪声、低通滤波、马赛克、信号增强、二次水印、剪切和缩放等操作有较高鲁棒性，特别是锐化、对比度增强、边缘增强、直方图均衡等信号增强处理几乎不影响水印的抽取。 |
