This paper research the mpeg - 4 standard first and realize the encoder and decoder of video of mpeg - 4. then the paper emphasize two key techniques in mpeg - 4 encoder : motion estimation and sprite encode. motion estimation takes the largest time in all parts of mpeg - 4 encoder. the paper concluded some typical me techniques, research and realize the mvfast arithmetic whice is recommend by iso, then improved mvfast by considering the temporal candidate motion vector and adjustal thresholds
然後，本論文重點研究了mpeg - 4編碼過程中兩項關鍵技術：運動估計和背景圖像編碼。運動估計是編碼過程中最重要，耗時最長的部分。本論文總結了常見的運動估計演算法，深入研究並實現了iso推薦的運動估計優化演算法mvfast ，在此基礎上，引入了時間參考運動向量和可調的門限參考值，對mvfast演算法進行了改進。 -
