针对视频目标的跟踪过程中目标之间遮挡和人体自遮挡的难题，提出一种基于运动轨迹的视频目标跟踪算法。介绍跟踪算法中常用的基于特征概率密度统计的 Mean-shift 跟踪算法原理，阐述所提算法。与 Mean-shift 算法做实验对比，对比结果表明，对于无遮挡和有遮挡情况下的目标跟踪，该算法在准确率方面比 Mean-shift 跟踪算法更高，具有更强的实用性。
針對視頻目標的跟蹤過程中目標之間遮擋和人體自遮擋的難題，提齣一種基于運動軌跡的視頻目標跟蹤算法。介紹跟蹤算法中常用的基于特徵概率密度統計的 Mean-shift 跟蹤算法原理，闡述所提算法。與 Mean-shift 算法做實驗對比，對比結果錶明，對于無遮擋和有遮擋情況下的目標跟蹤，該算法在準確率方麵比 Mean-shift 跟蹤算法更高，具有更彊的實用性。

Aiming at the fact that problems emerge during video target tracking process,such as,the block between the targets and the human self-occlusion.A trajectory based video target tracking algorithm was proposed.A brief introduction of the trac-king algorithm principles of statistical characteristics probability density based Mean-shift tracking algorithm was given,and the proposed algorithm was elaborated specifically,and through experimental comparison with Mean-shift algorithm,the proposed algorithm was verified to be better than Mean-shift algorithm in terms of the accuracy for the targets without shelter and shel-tered targets and has stronger practicality.
