Mean-Shift目标跟踪算法的带宽选取策略

Bandwidth Choosing Strategy of Mean-Shift Target Tracking Algorithm

分析不同带宽策略对Mean-Shift目标跟踪算法的影响,提出一种新的带宽策略。构造一个与目标窗口内接椭圆相似的椭圆,利用其长轴和短轴确定带宽,将此带宽策略纳入Mean-Shift算法中进行目标跟踪。实验结果表明,该策略具有良好的跟踪效果,能够有效降低时间复杂度。

The influence of different band strategies are analyzed. A new bandwidth strategy is put forward. Through structuring an ellipse being similar with target window＇s inscribes ellipse, it uses major axis and minor axis to identify bandwidth. This bandwidth strategy is integrated into Mean-Shift target tracking algorithm. Experimental results show this strategy has good effect on tracking target and reduces the time complexity.
