  • 例句与用法
  • But none appears to have the combinatorial rule system of human language , in which symbols are permuted into an unlimited set of combinations , each with a determinate meaning
    但是没有一个像人类一样使用复合的规则系统,在这个系统里面,有无数的组合形式,每个组合含有一个特定的意义。
  • But none appears to have the combinatorial rule system of human language , in which symbols are permuted into an unlimited set of combinations , each with a determinate meaning
    但是,没有一个像人类语言那样有组合法则体系,在这一体系中,各种符号经过排列可以生成无限的组合形式,每一种都有一个确定的含义。
  • The scanning lines of the image are permuted randomly to balance the energy distributing of the image scanning lines , then the watermark sequence is embedded in the image with the spread spectrum watermarking algorithm to produce the watermarked image
    提出基于像素置乱的数字水印稳健算法。通过对图像扫描行序列进行随机置乱,以平均图像扫描行序列频谱能量,然后采用扩频水印算法嵌入水印序列。
  • Researches the basis watermark managing works particularly and systemly . there are many works to do on watermak technology except watermark embedding and extraction arithmetics such as the watermark choosing , encoding , modulating , demodulating and the watermark capacity . these prior and ultimate works ensure that the arithmetic is brought into effect . just understanding these , this paper analyses and researches the basic watermark theoretics in many pages . it brings forward chaos modulation on watermark modulating , brings forward chaos permuting on image permuting , introduces bch encoding on letter watermark processing and discusses the approximate estimate of the watermark capacity in dct domain and dwt domain by applying the current communication theoretics . there works not only extend ways for the later work but also are significative on watermark research
    全面系统地研究了水印信号的处理技术数字水印技术除了水印嵌入和提取的算法外,还有许多工作需要做,如水印的选码、编码、调制、解调、能量的确定等等,这些预处理和后处理工作是算法有效实施的必要保证,正是基于这样的认识,本文利用较大的篇幅对水印的基本理论知识进行了详细的分析和研究,在水印的调制方面,提出了混沌调制法;在图像水印的置乱方面,提出了混沌置乱法;在文字水印的处理上,引入了bch编码;在水印容量分析方面,结合现代通信理论,对图像在dct域和小波域内的水印容量估算进行了详细的探讨,这些工作不仅为本文后期工作铺平了道路,而且对数字水印的研究具有重要的意义。

    针对多机场的非实时流量管理的模型,提出了基于排序的隐枚举法,它利用目标函数值大小的相对关系,对约束条件解进行排序,在最小解集中寻找最优解,以加快收敛速度。
  • In the part of image encryption , chaotic map based on kolmogorov flow is used to permute . changing the traditional stream - cipher , new chaotic pseudo - random sequence generator based on the theory of product cipher is presented to substitute the pixel . based on it , linear map to confuse the pixel is presented further , withstanding statistical attack
