視訊傳輸在多媒體通訊上扮演著一個很重要的角色，由於傳輸時會發生錯誤，使得強健的視訊傳輸在提供較佳的服務品質方面變得越來越重要。依據我們所提出新的可調式估計架構，這篇論文在強健的視訊傳輸方面發表了一個有效的混合式錯誤回復演算法。利用在受損區塊的鄰近區塊的資訊，受損區塊會被分為三種類型。依據受損區塊的類型，我們所提出的可調式估計架構可以採用Bzier曲面估計、第一階導數平面估計、或是較大群質心估計有效地回復受損的區塊。依據六種測試用視訊影像串列，實驗結果證明我們所提出的混合式錯誤回復演算法可以在不同的錯誤率下改進視訊品質與執行時間。
Video transmission plays an important role in multimedia communication. Due to transmission error, robust video transmission has become increasingly important in providing better quality of services. Based on our proposed novel adaptive estimation scheme, this thesis presents an efficient hybrid error concealment algorithm for robust video transmission. Using the information of neighboring
macroblocks (MBs) of the corrupted MBs, the corrupted MBs are classified into three types. According to the type of the corrupted MB, our proposed adaptive estimation scheme could adopt the Bzier surface estimation, the first-order plane estimation, or the centroid of major cluster estimation to conceal the corrupted MB efficiently. Based on six testing video sequences, experimental
results demonstrate that our proposed hybrid error concealment algorithm can improve the video quality and the execution-time performance over different lost rates.
