  2. This paper raised a new way for overlapping speech segregation based on sound localization cues. in this paper, we first divide the speech stream into some time - frequency regions and calculate the itd and iid of each region. then the notion of a " time - frequency " binary mask is given, which selects the target if it is stronger than the interference in a local time - frequency region

  8. 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。
  9. A wavelet visible watermarking algorithm is proposed based on noise masking, then the improvement is made based on texture feature of watermark image

    摘要根據圖像的噪聲掩蔽性設計了一種小波域可見水印演算法，並根據水印圖像的紋理特徵對演算法作了進一步改進。
  10. 1. speech enhancement method based on masking properties of the human auditory system is described. in this paper, a threshold is got through simulating the frequency of human auditory in order to reduce the musical residual noise and the background noise

    在閾值法除噪中閾值確定是極為重要的環節，本文模擬人耳聽覺掩蔽效應來確定閾值大小，以有效的掩蔽殘留的音樂噪聲和最大限度的保留語音。
  11. In order to adapt the scheme to both the color image and the gray image, while embedding the watermarking into the image, the scaling factors are determined by the local luminance feature and texture features of the image. it can improve the embedding strength and the watermarking robustness. from the experimental results, the stego - images are extremely robust to common image processing such as median filter, jpeg compression and denoising after adding the stochastic noises

    2 、提出了一種新的基於小波變換和紋理特徵的數字水印演算法，該演算法依據從圖像小波域提取出的紋理特徵來選取水印的嵌入位置，較好地利用了圖像的紋理區域，既能掩蔽較多的噪聲，又能較好地抵抗jpeg壓縮等一般性攻擊，調節了數字水印技術中存在的不可見性與魯棒性之間的矛盾。
  12. In natural environment, the signal always masked by interfering noise, that the critical problem is auditory system how to catch the signal under the noise conditions and what neural mechanism underlying it
