interframe coding 中文意思是什麼

interframe coding 解釋
幀間編碼
  1. A new bit rate control strategy with both global pre - allocation and local segmentation ( glas ) for low bit rate application is proposed. first, it allots bit date to every frame in advance according to possessive rate of buffer, and then distribute different quantization parameters according conctete detail. by means of this method, buffer is controlled more particularly. and the quality of decoded image is improved, the traditional video image coding method, that is to say, the intraframe coding based on dct and the interframe prediction coding based on motion compensation, is not suitable for low bit rate compression and aside from this, the encoder is too complicated

    它首先在總體上根據緩存器的佔有率給每幀預分配比特數,然後再根據具體細節給予不同的量化參數。使緩存器得到了更細致的控制,解碼圖像的質量有所改善。針對傳統的視頻圖像編碼方法,即幀內基於dct的編碼加幀間基於運動補償的預測編碼存在不適于低比特率壓縮,編碼器復雜等不足,討論了基於3 - ddct的xyz視頻圖像壓縮編碼方法,提出了3 - ddct系數的三維「 z 」形掃描方案,大大提高了編碼效率。
  2. An embedded wavelet quadtree interframe coding algorithm an embedded wavelet quadtree interframe coding algorithm

    一種嵌入式小波四叉樹幀間編碼演算法
  3. ( 2 ) interframe prediction model researching on the existing video scalable coding structure and the predict - tion model shows that the information between frames of video sequence was not utilized fully to improve coding efficiency in these coding scheme, especially the prediction of b frame in the enhancement layer

    ( 2 )幀間預測方式通過對這些主流可分級編碼方法的預測方式進行分析與研究表明這些方法並未能很好地利用視頻序列的幀間信息來進行幀間預測以提高視頻編碼效率,特別是對增強層b類幀的預測。
  4. Interframe predictive coding is used to eliminate the large amount of temporal and spatial redundancy that exists in video sequences and helps in compressing them. motion eliminate can help to eliminate these redundancy. different kinds of algorithms use different criteria for comparison of blocks

    它採用開放的編碼系統和新一代視頻編碼技術,它在視頻編碼發展史上第一次把編碼對象從圖像幀拓展到具有實際意義的任意形狀視頻對象,從而實現了從基於像素的傳統編碼向基於對象和內容的現代編碼的轉變。
