【導讀】我們提出一個目標跟蹤快速算法---用運動矢量數(shù)據(jù)來預測目標物體輪廓。擋恢復檢測來更新目標輪廓,并用塊向量預測目標邊界從而實現(xiàn)跟蹤。方案被用于運動估計。首先，從幀差中估計未遮。遮擋和遮擋恢復視為二元事件并對它們的關系做出詳細解釋。原理，將遮擋恢復檢測算法修改使之發(fā)展成為遮擋檢測算法。式上要優(yōu)于現(xiàn)存的基于區(qū)域的目標跟蹤方法。實現(xiàn)該該算法的程序采用了MPEG-4. 的視頻壓縮和基于標準的內(nèi)容檢索。初步的仿真結果展示了該算法的表現(xiàn)。視覺跟蹤已經(jīng)成為計算機視覺領域中被廣泛研究的一個課題。律進行合并，產(chǎn)生符合要求的網(wǎng)格。依靠光流估計對節(jié)點信息進行采樣，跟蹤節(jié)點。目標跟蹤系統(tǒng)的計算量的復雜與否取決于圖形分割、光流或是運動估計操作。步研究已包括在最后一節(jié)。運動估計是目標跟蹤中的根本要素，因此準確的運動估計是最重要的步驟之一。因此，運動估計比傳統(tǒng)的塊匹配技術要更加準確。
