On-line Handwriting Character Recognition using Directional Features and Direction-Change Features
Masayoshi Okamoto, Kazuhiko Yamamoto · IEEJ Transactions on Electronics Information and Systems · 1999
We propose a new on-line recognition method to recognize handwritten cursive-style Japanese characters correctly. Our method simultaneously uses both directional features, otherwise known as off-line features, and direction-change features which we designed as on-line features. The direction-change features express where in the mesh and in which direction the character's coordinates change. These features express both written strokes in the pen-down state and unwritten imaginary strokes in the pen-up state. The recognition rate was improved by our method over the traditional method using only directional features.
