Abstract(in Japanese) (See Japanese page)
Abstract(in English) A new type of features - ridge features - for the recognition of grey-scale handwritten characters is proposed. The ridge features are defined along the ridge lines in the grey-scale image as having the orientation of the ridge. Compared with the conventional features calculated from the contour lines of characters, the ridge features have simpler structures with less redundancy, and represent the characters more accurately in the intersections and ends of strokes. The ridge features yield a higher recognition rate than the conventional ones by 2.29% in an experiment on the data of the ETL9G database using the Euclidean metric.
