摘要: 传统Harris检测算法不能很好地适应跟踪环境。为此,提出一种基于角点特征融合的Mean-shift跟踪算法。考虑人体姿态变化或遮挡对多区域跟踪的影响,采用角点更新策略,将特征融合主色调模型的跟踪结果与多区域跟踪结果进行权衡。实验结果表明,该算法能克服人体姿态变化或遮挡对跟踪的影响,实时性满足一般跟踪系统的要求,且在非遮挡状况下,其跟踪准确率比传统算法高。

Abstract: For traditional Harris detection algorithm cannot suit the situation of tracking well, a algorithm of corner point detection which depends on different ellipse regions is proposed. For the influence of body attitudes variation or occlusion, a strategy of points updating is adopted simultaneously. The result of multi-zone tracking against the global tracking based on dominant hue and multi-features fusion is balanced. Experiments show the algorithm proposed can overcome the body posture change or occlusion effectively, meets the requirement of real-time, and the accuracy of tracking in non-occluded environment is also higher than traditional algorithm.
