PATTERN RECOGNITION DEVICE, ITS METHOD AND COMPUTER READABLE RECORDING MEDIUM RECORDING PROGRAM FOR ALLOWING COMPUTER TO PERFORM THE METHOD

摘要

PROBLEM TO BE SOLVED: To quickly and efficiently narrow a candidate pattern in the case of recognizing a pattern such as a handwritten character. SOLUTION: A preprocessing part 12 preprocesses picture data inputted by an image input part 11, a feature extraction part 13 extracts a feature and a candidate selection part 16 selects a candidate category by using a Euclidian distance. Then a candidate narrowing processing part 17 narrows a candidate category by using a projection axis and a recognition processing part 18 recognizes a character.
