Segmentation method for touching handwritten characters based on connecting condition of neighbor lines

摘要

Abstract Recently the accuracy of isolated character recognition is improving. In the unconstrained handwritten character strings, there are many touching characters, and the segmentation of the touching characters is required as preprocessing of isolated character recognition. But conventional segmentation methods using vertical lines can't segment comp1icated touching. In this paper, we propose a new segmentation method based on connecting condition of neighbor lines, and evaluated the efficiency of this method for real mail address in Japanese.
