One of the most difficult problems in handwritten Kanji (Chinese) character recognition is the variety of writing styles. In Japan, children are taught to write beautiful characters in elementary school. However, the shape of handwritten characters can vary in such propositions that the recognition rate greatly depends on character quality. Therefore, developing an automatic evaluation system of handwritten characters is very effective in improving our writing and also helps to build an accurate character recognition system. For this purpose, a real-time evaluation system consisting of a new algorithm for evaluating handwritten character quality has been developed. This objective evaluation is carried out by assuming that character quality can be expressed as a linear function of quantitative measures. Such measures were derived from the results of an analysis of character evaluation factors. The scanner digitizes handwritten characters and the workstation calculates their quality. The accuracy of this system was confirmed, comparing it to subjective evaluation by human observers. The possibility of objective evaluation of handwritten character quality was demonstrated.
