Stroke-by-stroke Order Evaluation of Online Handwritten Kanji Characters using Directional Feature

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a stroke order evaluation method for online handwritten Kanji characters written on a tablet. Previously, we presented a method employing shape context feature around each feature point. In this paper, we propose a method that extracts directional features around a focused feature point in square areas divided by horizontal and vertical grids. As often employed for character recognition, the method divides a handwritten Kanji pattern into 8 * 8 squares and extracts 8 directional features from each square. An experiment using 1,005 kinds of Kanji characters shows that the proposed method evaluates stroke order correctly by 97.5% with the maximum time of 0.05 sec. /character. This accuracy is less than 98.4% of the previous method by 0.9 points, but its speed is more than two times improved from 0.12 sec. We also made another experiment for 26 kinds of Kanji characters which are often written in wrong stroke order. The experiment shows that the proposed method evaluates stroke order correctly by 97.9% with the maximum time of 0.01 sec. /character. This accuracy is less than 98.6% of the previous method by 0.7 points, but its speed is more than three times improved from 0.03 sec.
