Abstract
We propose an on-line character recognition method that simultaneously uses both directional features, otherwise known as off-line features, and direction-change features, which we designed as on-line features. The directional features express the location and direction of each character’s coordinates. The direction-change features express where and in which direction the character’s written and unwritten imaginary stroke coordinates change, and the location of the circular parts of the character. We found suitable direction-change features with the imaginary strokes. The recognition rate was improved by our method, in comparison to the traditional method using only directional features.
