摘要:

近年来提出的各种行人检测器鼓励了一些工作融合行人检测器,以实现更准确的检测。其背后的直觉是根据其空间共识组合检测器。我们提出了一种新的方法,称为基于内容的空间共识(CSBC),其中,除了依赖于空间的共识,认为检测窗口的内容来学习加权融合的行人检测器。其结果是减少了假警报并增强了检测。在这项工作中,我们还证明了用于学习每个检测器的窗口内容的特征的影响很小,这使得我们的方法即使采用简单的特征也是有效的。CSBC克服了ETH数据集和加州理工学院数据集中最先进的融合方法。特别是,我们的方法是更有效的,因为更少的检测器是必要的,以实现表达的结果。

英文摘要:

The variety of pedestrians detectors proposed in recent years has encouraged some works to fuse pedestrian detectors to achieve a more accurate detection. The intuition behind is to combine the detectors based on its spatial consensus. We propose a novel method called Content-Based Spatial Consensus (CSBC), which, in addition to relying on spatial consensus, considers the content of the detection windows to learn a weighted-fusion of pedestrian detectors. The result is a reduction in false alarms and an enhancement in the detection. In this work, we also demonstrate that there is small influence of the feature used to learn the contents of the windows of each detector, which enables our method to be efficient even employing simple features. The CSBC overcomes state-of-the-art fusion methods in the ETH dataset and in the Caltech dataset. Particularly, our method is more efficient since fewer detectors are necessary to achieve expressive results.
