Abstract最近的研究发现,在对称正定流形上可构造一种改进的李群结构,并赋予具有双不变度量性质的对数-欧几里得黎曼度量,所得到的距离公式和黎曼均值均呈现简单形式。据此,利用目标的综合特征构建区域协方差阵为目标建模,提出一种基于改进李群结构的特征协方差目标跟踪方法。实验表明,这种跟踪方法实用有效,在相同的条件下,因为算法的计算量的减少,跟踪性能略优于基于仿射黎曼度量的协方差目标跟踪。
Other AbstractRecent research shows that an improved Lie group structure can be constructed on the symmetric positive manifold.This will lead to a bi-invariant log-Euclidean metric,which makes the distance formula and Riemannian mean take a much simpler form.We model the tracked object with its covariance feature of the interest region and propose a feature covariance tracking method based on the improved Lie group structure.Experimental results show that this method is practical and efficient.Under the same tracking con...
