Structure of local feature for target recognition

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.
