| Abstract(in English) | Nearest Neighbor (NN) search is essential for case/instance based reasoning. Most NN search methods proposed so far are based on NN candidate narrowing and these methods degenerates to brute force search in highdimensional space over 30D. For solving this problem, we have been proposed PC-tree that is modifed the kd-tree by replacing a space dividing axis by a principal axis of prototypes. However, the method achieved insufficient accelaration because the method required inner producets between an input image and each dividing axis. In this paper, we propose an accelerated inner products between images by using integral image and apply it to the nearest neighbor image search with PC-tree. |
