Abstract
A pattern matching multiplies distances between an input pattern and standard patterns by distance-scale correcting weight coefficients respectively prepared for the standard patterns. This yields a distance corresponding to a category shape of a standard pattern and enhance an input pattern recognition ratio. A pattern recognition apparatus stores distance-scale correcting weight coefficients respectively prepared for all standard patterns in storage means. Distances between stored standard patterns and an input pattern generated by input pattern generating means are calculated. The calculated distance is multiplied by a weight coefficient stored in the storage means in accordance with the standard pattern used for calculating the distance from the input pattern. This structure reduces the number of templates when providing the standard patterns as multiple templates and, at the same time, enhances the input pattern recognition ratio.
