Kind Code:

Abstract:
PURPOSE:To exactly segment a character from a character picture in an undetermined form by finding out a segmenting position from the value of peripheral distribution only when a candidate segmenting position does not exist at the time of character extraction. CONSTITUTION:A CPU 101 segments the character one by one from the character picture, which is read by a picture input device 102, in a RAM 105. At first, the standard character height of the character and the tickness of a line are estimated from the peripheral distribution in a row direction and next, a standard character interval, word interval and standard character width are estimated and the extraction of a word is executed. Then, the candidate character segmenting position is estimated. For the segmentation of the character in the extracted word, the like component of the character is extracted and simultaneously, the height and width of the character are extracted. When the width of the character exceeds an allowable size, the extraction of a contour is executed again. When the candidate character segmenting position does not exist, a candidate character segmenting range is determined according to the peripheral distribution in a direction vertical to the row direction and the extraction of the contour is executed again. Then, only the inside of the area is extracted and the character is segmented. Thus, the character picture in the undetermined form such as the character picture, in which the peripheral distribution is overlapped, etc., can be exactly segmented.
