Abstract

Abstract: Recently local feature based target recognition is becoming one of hot topics in computer vision.On the base of bag-of-word method only using appearance，this paper proposes a star model，which connects the location information of local key-point，composed of some parts depending on a landmark.It introduces the structure of image local region and reduces the complexity of full model.Experiments show that the proposed algorithm outperforms bag-of-word method in classification and realizes localization effectively.

Key words: local feature, structure, target recognition

摘要： 基于局部特征的目标识别成为计算机视觉研究中的一个热点。该文在词袋方法仅利用目标外观信息的基础上，将局部特征点的位置信息建模为星形模型，模型由固定部分组成且仅依赖于标志位置。引入图像局部区域的几何结构信息，同时降低了全模型中各个部分依赖的复杂性。实验证明该方法的分类效果优于词袋方法，并能有效实现目标定位。
