Examples
- According to an approximate estimate ,
根据大约估计, - According to the different anticipated damage degree , the network output makes an approximate estimate of the length of structure use
根据不同的预期破坏等级，网络的输出给出了结构使用寿命的近似估计。 - According to approximate estimate , there are more than ninety intersections along these five loops . thus , this paper takes jinsong intersection for example , anatomizes the existent problem , and finds out
因此，下面将以劲松平面信号交叉口进行典型研究，剖析此类平面信号交叉口存在的问题，以期找出提高其通行能力的对策。 - 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。
