Handwritten Chinese Character Recognition by Background Propagation Method

Abstract (in Japanese) (See Japanese page) 
(in English) In the field of character recognition, many feature extraction methods are proposed.
Those are the methods extract features from character shapes themselves like a weighted direction index histogram method.
But features must exist also in the background of the character pattern.
Here we propose a background propagation method as a new character recognition method which propagates the directionality of the stroke to the background.
In this method, the features which are robust and stable to the position variation are obtained by using the gradation of the contour directionality and two dimensional Gaussian filter.
From the recognition experiment to all characters in ETL9B, the method is effective in handwritten character recognition because the recognition rate is higher than that of the other method.
