Structured low rank tracker with smoothed regularization

In this paper, we propose a structured low rank learning algorithm with smoothed regularization for robust object tracking, under particle filter framework. Specifically, the relationships among the particles are exploited with structured low rank regularization term, and simultaneously handle the outlier using a group sparsity regularization. The label information from training data is incorporated into the tracking objective function as the classification error term and idea coding regularization term respectively. By the smoothed regularization, the developed structured low rank learning based tracker can be efficiently solved by iterative reweighed least squares algorithm(IRLS), and avoids svd operation. Moreover, the collaborate normalized metric is developed to find the best candidate. Compared with some state-of-the-art tracking methods on 50 challenging sequences, the proposed algorithms perform well in terms of accuracy, robustness.
