  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

    演算法簡單描述如下：首先用一個環形自同構映射把要嵌入的數字水印映射成偽隨機噪聲，然後把該偽隨機噪聲嵌入到宿主數據頻域的低頻段中，接著把得到的頻域系數進行相應的逆變換得到嵌入水印的圖象，最後對該嵌入水印的圖象進行視覺掩蔽處理。
  2. We find that all the results are quite different between each original emg and its ten surrogate data, i. e. emg is not a linear random noise, but a nonlinear deterministic signal ( though it does not like a low dimensional chaos )

    也就是說，肌電不是線性隨機的噪聲，而是非線性的確定性信號（盡管它並不象是低維混沌） 。
