Abstract
In a method of extracting feature quantities of a character, a pair of region dividing lines which intersect a character image are obtained by using generated projections of direction codes. Then, a reference position for extracting feature quantities of the character is decided by finding positions at which the region dividing lines intersect the character image. Thereafter, the feature quantities of the character having the reference position are extracted by subjecting the codes of the divided segments to a predetermined operation for obtaining information regarding a shape of each of the divided segments.
