| Abstract(in English) | We propose a fast, precise pre-classification method for a lot of categories. Conventional pre-classification uses simpler discrimination functions than those used by detail-classification. But sufficient simplification for matching acceleration sacrifices some degree of matching accuracy. On the other hand, the proposed method can preserve the accuracy of the detail-classification and achieve drastic acceleration of matching process by holding a mapping from low-dimensional reference features to candidate category sets by estimating projections of each category's feature regions used in the detail-classification. The proposed method applied to Japanese character recognition can accelerate matching process by 3 times over the conventional method with no decrease of matching accuracy, which confirms the effectiveness of the proposed method. |
