  1. Loss of information during transmission of compressed video over error prone networks may lead to objectionable visual distortion in the decoded video, and such distortion can propagate to many frames because of the motion compensated prediction and the variable - length coding used

    採用運動補償預測及可變長編碼的壓縮視頻數據,在極易發生干擾的網路環境中傳輸時,通道傳輸差錯對壓縮編碼圖像質量影響很大,有時甚至會導致整個視頻通信完全失效。
  2. 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。
