ABSTRACT:
A hand-written character recognition apparatus and method in which line element data obtained from an output hand-written stroke is converted to a plurality of sub-strokes satisfying a tracing condition in accordance with a tracing command described in a character dictionary data base, substrokes satisfying the tracing condition are selected in accordance with a selection command described in the character dictionary data base, then on the basis of an assumption that the hand-written stroke is a set of sub-strokes, the hand-written character is recognized by evaluating the shape of the sub-stroke by employing a shape evaluation command and by evaluating a position evaluation command derived from the character dictionary data base, whereby a hand-written character, such as a distorted hand-written character and so on, can be recognized with ease.
