| Abstract(in English) | This paper describes a method for generic object recognition using graph structural expression. In recent years, generic object recognition by a computer is strongly requested in the field like the robot vision and the image retrieval. Conventional methods use bag-of-features (BoF) that express the image as an appearance frequency histogram of visual words by quantizing SIFT (Scale-Invariant Feature Transform) features. However, there is a problem that the location information and the relations between keypoints are lost that are important as structural information. To deal with this problem, in the proposed method, the graph is constructed by connecting SIFT keypoints by the line. As a result, the keypoints have the relation, and then structural representation with location information is achieved. Since the graph representation is not suitable for the statistical work, the graph is embedded into a vector space according to the graph edit distance. As a result of two image datasets, the proposed method has improved the recognition rate compared with conventional methods. |
