Abstract
PURPOSE:To stably recognize even a character string, which is written on a form having no character frames, with a high precision by obtaining the segment direction of each character based on the relative coordinates of each character string. CONSTITUTION:The direction of characters is measured 2 on preliminarily determined coordinates in accordance with a given picture to obtain 3 absolute directions of segments of the input picture. Distribution of character lines in each direction is obtained 3. At this time, this distribution is obtained with respect to a character string to obtain directions on the picture of horizontal and vertical directions as the reference of the character string. Relative coordinates of each character string are obtained based on this distribution, and a direction code is assigned 4 again based on these coordinates to obtain 5 a stable direction picture. The picture of the character string is taken as the input picture and characters are successively read from the first, thereby reading the character string which has a large variance in character shape and character arrangement and is written on a form having no character frames.
