在計算機視覺領域,多目標跟蹤（MOT）一直是困難且具有挑戰(zhàn)性的研究。在該領域中,計算數(shù)據(jù)量很大,并且算法的處理速度要求很高,因此跟蹤速度、效率和精度常常難以很好地平衡。由于這個原因,將單目標跟蹤中使用的具有通道和空間可靠性的判別相關濾波器（DCF-CSR）用于MOT,以在保持跟蹤速度的同時確保跟蹤效果。本文分為以下四個部分:（1）目標檢測。由于2D MOT 2015和MOT16數(shù)據(jù)集目標的檢測存在錯漏,提出將基于更快區(qū)域的卷積神經(jīng)網(wǎng)絡（Faster R-CNN）用于目標檢測,并且將數(shù)據(jù)集提供的結果替換為網(wǎng)絡檢測的結果。（2）目標跟蹤。為了在MOT中添加目標外觀數(shù)據(jù),并結合速度和準確性因素,本文使用DCF模型。但是,已經(jīng)發(fā)現(xiàn)執(zhí)行多目標跟蹤數(shù)據(jù)集時跟蹤結果并不理想,因為DCF算法不支持多尺度。為克服此困難,本文解決了計算檢測目標框和預測目標框之間的交并比（IOU）并使用檢測目標框代替預測的方法。₃數(shù)據(jù)關聯(lián)。對于第（2）部分的IOU的計算,這是一批檢測框和一組預測框之間的相互計算問題,本質上是任務分配和優(yōu)化問題。為此,匈牙利算法被用于確定目標之間的最佳相關性。（4）對象...
