Abstract
The purpose of this paper is the segmentation of touching handwritten Japanese characters to enable each segmented character to be recognized. Though segmentation methods cooperating with recognition for the simple characters are known, they are not applicable to complicated characters such as kanji. To estimate the ability of segmentation itself, our method does not use any results of character recognition but segments touching characters using some specific features of character patterns. Linear components in patterns are extracted as features and a segmentation method based on them is proposed. A database, which contains character pattern and ground truth is constructed. In the database the ground truth data describe the correct areas of touching points judged by plural human subjects. As a result of the segmentation experiments, about 64% of touching patterns can be segmented at appropriate points. This correct segmentation rate is automatically calculated consulting the ground truths.
