靜音版
英文
gh-pcu22-se-
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。The center s booth at the exhibition showcased master s artwork, books, dvds, videos, cds and audiocassettes
靜態方面展示清海無上師的藝術創作書籍以及dvd等影音出版品。In chapter 2, a general digital watermarking frame is presented, including the generation, embedding and detection of watermark. in chapter 3, the concept of watermarking channel is presented, the modes of watermarking channel and image dct coefficients is proposed, the capacity of watermarking channel is evaluated by embedding watermarks to selected still image dct coefficients in direct spread spectrum. in chapter 4, a watermarking algorithms based wavelet multi - resolution is presented, by conjunction with human visual model, it keeps invisibility of watermark in host image and need not original image during detection
數字水印是一種新的數字媒體保護技術，它是將特定的信息（如版權信息、秘密消息等）嵌入到圖象、語音、視頻等各種數字媒體中，以達到版權保護等目的，同時，這種信息對宿主媒體的影響不足以引起人們的注意且有特定的恢復方法，此信息對非法接收者應該是不可見的，本文主要對數字水印的一般框架，靜止圖象dct系數的理論容量，圖象水印的嵌入和檢測，數字媒體防篡改以及數字水印的攻擊等問題進行了研究，提出了兩個新的水印算演算法。
