| Abstract(in English) | Segmentation of characters freely written on the paper is a difficult problem for a computer system. We propose in this paper the method to solve this problem by computing likelihood of characters in segmentation process based on a subspace method. At first, a binary image on which characters are written, is scanned by a fixed size of a window. At every scanning location, feature vectors are obtained and projected to each character subspace. The character recognition using subspace method is carried out and character name and its confidence are obtained. The confidence is computed as the length of the normalized projection vector to the character subspace. In this paper, character segmentation and recognition experiments were carried out using mesh feature as well as direction histogram for isolatedly, normally and connectedly written characters. As a result, one subspace of mesh feature with one dimension showed high accuracy of character segmentation for isolatedly and normally written characters. For connectedly written characters, multiple subspaces of direction histogram improved character segmentation rate. |
