Abstract(in English) | We have proposed an image retrieval based object tracking and recognition method. In this method, nearest neighbor (NN) search within an image database is performed for the object image extracted from input frame. For this search, we have proposed an approximate NN search algorithm based on Nearest First Traversing Graph (NFTG), which utilizes the previous search result as the starting point of the next search. However, the computational complexity of this graph construction is O(dN^2), where N and d are the number of images in the database and the dimensionality of each image data respectively. This construction algorithm is not suitable for the interactive application that stores user specified object images one by one. In this paper, we propose an incremental tree construction algorithm whose complexity is O(dN) for storing a single object image. Through the experiments, we confirmed the effectiveness of our new graph construction algorithm. |
