  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。

  13. Motion compensated prediction error image has significant amplitudes mainly along the boundaries of moving objects, correspondingly its wavelet coefficients contain large energy in high frequency bands. this greatly reduces the coding efficiency of ezw. it is first provided that the correspondence between the significant amplitudes area of the mcp error image and the wavelet coefficient significant map, then encode the significant map efficiently using quadtree approach, followed by bit - plane coding the significant coefficients to produce an embedded data stream. experiment result shows that compared to ezw and zte, the proposed algorithm is more efficient and has better performance

    演算法對于運動補償余量誤差幀首先進行小波變換，並選取適當的閾值，用重要圖表示大於該閾值的重要系數。根據殘差幀小波系數的統計特性，用四叉樹方法編碼重要圖，並對重要系數作位面編碼，生成嵌入式碼流。實驗表明，與ezw ， zte等演算法相比較，該演算法編碼效率高，復現圖像質量好。
