Abstract

PURPOSE: To determine the kind of an input character correctly by limiting proposed characters by stroke shape features when character recognition is not fixed unconditionally by the position relation of strokes.
CONSTITUTION: The size of a real-time input character expressed by a time series of strokes is normalized by normalizing circuit 2 and on the basis of the number of representative points from representative-point-number determining circuit 3, representative-point coordinate determining circuit 4 finds coordinates of representative points dividing strokes. In addition, relative position matrix extracting circuit 5 extracts a relative position matrix among representative points and position matrix matching circuit 6 matches the relative position of the character with position matrix dictionary 7 within the range of a proposed category narrowed by proposition selecting circuit 11 by the number of strokes. Then, the category is narrowed and applied to stroke-shape-feature matching circuit 9 and shape features extracted by stroke- shape-feature extracting circuit 8 are collated with stroke-shape-feature dictionary 10 to limit proposed characters, thereby determining a proposed character which could not be determined by the position relation.
