Proposal of a method to update template images for holistic matching according to the width of character

In this paper, we propose a method to update numeral template images according to the width of characters for holistic matching. The purpose of our study is to develop a method that discriminates between correct patterns and incorrect patterns by matching input images against template images. We applied this method to handwritten class marks of book labels to assist librarians in Japanese libraries to find misshelved books. In experiments, initial numeral template images are gathered randomly from isolated characters. We confirmed that the proposed method is useful to increase the variation of the width of template images.
