摘　　要：对跟踪-学习-检测(Tracking-Learning-Detection,TLD)目标跟踪算法进行改进,在原算法中的跟踪模块和检测模块之间引入了帧间差检测方法,将帧间差法检测到的含有前景目标的窗口传送给TLD检测模块的级联分类器,提高算法的效率以及准确性。并对TLD算法中的重叠度重新定义,提高了该算法的跟踪成功率。通过实验对改进前后的TLD算法进行分析比较,证明改进后的算法具有更高的跟踪效率以及成功率。Improved Tracking-Learning-Detection （TLD） target tracking method to increase the efficiency and accuracy, by using frame difference detecting method between the tracking module and the detection module, and then send the output windows in which there is the tracking target to the cascade classifiers of the detection module. Also defined a new expression of overlap in TLD, by using which increased the tracking rate of the original algorithm. The results of experiments show that the improved method has higher efficiency and tracking rate than original TLD.
