摘要
基于多线索融合的跟踪是跟踪领域近年来的研究热点之一,该文结合两种常用的线索融合方式:乘性融合及加权和融合,提出一种融合策略自适应的鲁棒跟踪方法。该方法使用粒子滤波技术,统计样本的二阶中心矩并求Frobenius范数以表征线索的受噪声污染程度,最后适时切换两种融合策略。实践证明,新的融合策略比传统单一的融合方式更鲁棒。
Multiple cue fusion based tracking is one of the most active research in tracking literature. In this paper, a novel adaptive fusion strategy is proposed for multiple cue fusion, base on two common used fusion rules: product rule and weighted sum rule. This strategy employs particle filtering technique, estimating second order moment of the weighted sample set and computing its Frobenius norm to denote how cues are reliable, and then switch the two fusion rules in time. In practice, the new fusion strategy shows more robustness than traditional single fusion rule.
