Collection and analysis of on-line handwritten Japanese character patterns

Abstract

This paper describes our second collection of online handwritten character patterns and their analysis. 163 writers presented about 10,000 character patterns, covering 4,438 categories mainly in the context of sentences. Together with our first collection, the Kuchibue database containing 12,000 patterns from 120 writers, we have now collected about 3 million patterns. For this second collection of online patterns, named Nakayosi, we analyzed stroke number and order variations.
