| Abstract(in English) | We have proposed an image retrieval based object tracking and recognition method. This method consists of two techniques: Pose Parameter Embedding (PPE) and approximate nearest neighbor search based on Nearest First Traversing Graph (NFTG). PPE is a technique for image retrieval based object tracking, which stores misaligned object image with pose correction parameters for updating object position, scale, and orientation. PPE requires many misaligned images stored in the image database, and it reduces the scalability of the method. In this paper, we propose an extended method incorporating Chamfer matching with the NFTG based NN search. Since our method does not use PPE, it drastically reduces the number of images in the database. Also, it improves the stability against the illumination change, because Chamfer matching uses edge images. The asymmetric property of the Chamfer metric makes NFTG directed graph. Through the experiments, we confirmed the effectiveness of our method. |
