行人检测分类器的研究与设计

Research and Design for Pedestrian Detection Classifier

行人检测的重点在于分类器的设计,分类器的性能直接决定了行人检测的精度。选定样本特征和分类器类型之后,设计的关键就在于建立合适的行人和非行人样本库。因此,建立样本库并训练形成分类器是非常重要的工作。自建行人样本库,提取样本的梯度向量直方图特征,利用支持向量机获得行人分类器,并对分类器的性能进行测试。

The key of the pedestrian detection is the design of the classifier,which directly determines the accuracy of pedestrian detection.After the characteristics of samples and the type of classifier are chosen,the key of design is to establish proper pedestri an and non-pedestrian sample library.Therefore,the establishment of sample library and the training for classifier are important works.Pedestrian sample library was built and the Histogram of Oriented Gradient feature of the samples was extracted.The pe destrian classifier was obtained using support vector machine,and the performance of the classifier was tested.
