Extraction of Character Strings from House Maps Takmnasa Simasaki and Toyohicle

In this paper, we propose an experimental extmction method of character strings from house map images, using tlie block information. Our method consists of two steps: the first is to recognize the block information, and the second is to extract character strings with respect to the recognized block infonation. In comparison with urban maps, which have often been investigated for extraction subject of character strings, house maps are characterized as (1)utilitation of many different kinds of character sets; and (2)illustration with different directions of character strings or characters. Our method is applicable to these features. This paper does not only describe our method, but also evallintes the effectiveness through experiments.
