- Example Sentences:
| 1. | In general , a watermark system must satisfy the two basic requirements : imperceptibility and robustness . in this thesis , we proposed a frequency - based watermarking algorithm using toral automorphisms , in which a kind of toral automorphism is employed to mix a recognizable binary image ( bw ) , which contains the copyright information , into a noise - like signal
算法简单描述如下：首先用一个环形自同构映射把要嵌入的数字水印映射成伪随机噪声，然后把该伪随机噪声嵌入到宿主数据频域的低频段中，接着把得到的频域系数进行相应的逆变换得到嵌入水印的图象，最后对该嵌入水印的图象进行视觉掩蔽处理。 | | 2. | The embedded bw also successfully survives cropping , filtering , noise and multi - watermarking etc . the new ideas the thesis proposed are : first , frequency - based watermarking idea using toral automorphisms is really a novel one , although , in the literature , there are some waterniarking schemes using toral autpmorphisms , all of which are based on space ; second , some improvements of the quantization function contribute to the algorithm ' s performances to some degree
另外该算法对图象裁剪、滤波、噪声和多重水印处理等都具有较强的鲁棒性。本文提出了两个新思想：第一，虽然现有文献已经提出了利用环形自同构映射的数字水印处理算法，但这种算法是基于空域的，而利用环形自同构映射基于频域的水印处理算法，目前文献上未见报道。 |
