Multiple person tracking based on slow feature analysis

Object tracking is one of the most important components in numerous applications of computer vision. However, it still has many challenges to be solved, such as occlusion, matching, data association, etc. In this paper, we proposed to utilize slow feature analysis (SFA) method to handle the multiple person tracking problem. First, the part-based model is utilized to detect pedestrian in each frame. Then, a set of reliable tracklets is generated by utilizing spatial-temporal information of detection results. Third, SFA method is leveraged to extract slow-feature for these reliable tracklets. Finally, the traditional graph matching method is utilized to handle data association problem and consequently generate the final trajectory for individual tracking object. Some popular datasets are used in this study. The extensive comparison experiments demonstrate the superiority of the proposed method.
