摘要
现有的MeanShift跟踪方法使用单一半径参数描述目标大小变化,不能适应复杂的目标运动情况。使用带宽矩阵来描述目标尺寸,在两个方向上独立描述目标大小变化,提出并证明了一种新的跟踪方法。实验表明,在不增加任何计算量的情况下,该算法对目标运动的适应性更好。
Current Mean Shift tracking algorithm uses a single radius parameter to describe the scale of the object. This is not suitable for complex movements of objects. Provides a new algorithm in which bandwidth matrix is employed to describe the objects with two directions determined independently. The strict proof of the algorithm's convergence is given. Experimental results show the better adaptability of the new algorithm to object's movements without additional computational cost.
