  1. Resemble with the digital watermark methods of the other media such as still image and video, digital audio watermark must account for some problems which consist of perceptual transparency, data bit rate, robustness, security and real - time etc. the robustness of watermark is vital to the practical application, which requires the watermark providing with significant data since it suffered from some intended attacks or unintended revisal

    與靜態圖像、視頻等數字水印方法類似，音頻水印的研究主要須解決感知透明性、數據嵌入率、魯棒性、安全性以及實時性等問題。水印演算法的魯棒性對于實際應用來說是至關重要的，它要求數字水印在遭受有意的攻擊或無意的修改後，仍能提供有意義的數據，這一性能對版權保護的應用顯得尤為突出。
  2. To represent a feeling of transparency with zero gravity, the form, material and color of the building are carefully considered, this will show the impact on the mentality and physiology of person from the digital age

    建築在形象上傳達一種無重力的透明感，從形態的構成，材料的運用，色彩與燈光的組織，都圍繞著這一主題，以表現信息時代給人們心理和視覺上帶來的沖擊。
  3. Picture includes a photograph, transparency, negative, digital file, design, artwork, painting, montage, drawing, engraving, graphics, image and caption or any other item which may be offered in whatever format or media for the purposes of reproduction

    圖片一詞，應包括照片投影片負片數碼檔案設計插圖圖畫剪輯繪圖版畫圖形圖像及標題或任何其他為復制用途而以任何格式或媒體提供的項目
  4. Therefore, all - optical network effectively overcomes the electronic bottleneck introduced by complicated digital cross connection equipments, accomplishes fast bit rate, great capacity and good service quality communication, and possesses the transparency for bit rate, data format and modulation means of signal

    因此，全光網路有效地克服了復雜的電數字交叉互連設備的「電子瓶頸」 ，實現高速率、大容量、高質量通信，並且對信號速率、數據格式和調制方式透明。
  5. Circular symmetric spread spectrum digital image watermarking using chaotic sequences as the watermark takes advantage of the discrete fourier transform properties and spread - spectrum communication techniques to embed a circular symmetric watermark in the frequency domain. the watermark can be detected without the presence of the original image even when the watermarked image suffers geometrical attacks such as translation, rotation and scaling. experimental results show that the proposed scheme has good transparency and highly good robustness to geometric transformations

    基於混沌序列的圓對稱擴頻水印方案是以實值混沌序列作為水印，根據離散傅立葉變換的特性並結合通信上的擴頻技術，將一圓對稱水印嵌入到了圖像的頻域中，且即使圖像遭受了平移、旋轉、縮放等幾何攻擊檢測水印也不需要原圖像。
  6. A new type of blind watermarking technology, which has the advantage of adopting watermarking embedding algorithm is introduced based on wavelet transform and cosine transform, so the original image isn ' t necessary when picking up watermarking and the transparency and robustness of digital watermarking system is well fulfilled, the attack in the forms of noise, median filtering and compress can be withstood, and high pass filtering and low pass filtering can also be endured

    摘要詳細介紹了基於一種新型的基於小波變換和餘弦變換的盲水印數字水印技術，這種方法的一個顯著的優點就是採用水印嵌入演算法，提取水印的時候不需要原圖象，能夠很好的滿足了數字水印系統的透明性和魯棒性，能夠經受住加入噪聲、中值濾波、壓縮等方式的攻擊，並且還能夠經受住高通濾波和低通濾波。
