局部加权距离度量的双向稀疏表示目标跟踪
Target Tracking of Bidirectional Sparse Representation of Local Weighted Distance Metric
摘要
Abstract
We first propose a framework about target tracking model based on bidirectional sparse representation,which uses the L1mini-mization to constrain the forward and reverse reconstruction errors.The positive and negative sparse coefficient matrices are obtained by the algorithm of accelerated approximation gradient(APG).In this paper,we obtain the weight matrix according to the distance between the positive and negative template set and the candidate template set.By using the weight matrix and the positive and negative sparse coef-ficient matrix,the candidate samples with the largest positive and negative difference between the candidate samples are obtained,of which the optimal candidate samples are selected as the tracking optimal target.And then on the distance between the target template set and the candidate sample set,because the traditional Euclidean distance is inaccurate in the case of occlusion and illumination of the target,we propose an improved local weight distance measurement method.Compared with the traditional target tracking algorithm,the proposed al-gorithm has high robustness in the complex environment video sequence.关键词
