Title: Character recognizing method
Inventor: NAKAMURA NOBORU
IPC: G06K9/20
Filed: 1990-10-31
Abstract: PURPOSE:To perform character recognition by a full automatic system by deciding the orientation of an original from vertical and horizontal writing information and the position of a punctuation. CONSTITUTION:Divided areas are further divided into eight black picture element link small areas, and the area with small quantity of dispersion in the distribution of the interval and size of the area is extracted as a character area. The horizontal and vertical oblique shades of an extracted character area are taken out, and vertical/horizontal writing can be decided from the size of the valley of the shade. A punctuation candidate is extracted from the position and size of the eight black picture element link small area, and the character recognition is performed. In such a case, the orientation is decided based on the position of the punctuation in a punctuation area, and when all the punctuations are rejected, the recognition is performed by four patterns in which several ordinary character patterns are rotated by 90 deg., 180 deg., and 270 deg. as it is. In such a way, the character recognition can be performed by finding the punctuation area, and specifying the direction of a character corresponding to the position of the punctuation in the area.
