ABSTRACT

Chinese character education uses the method of writing and practicing according to the letter rather than learning the meaning and the sound of the word. When making Chinese character education application, therefore, it is necessary to deal with the technical method of recognizing and writing according to the Chinese characters for increasing the effectiveness of education. In this study, we try to find an effective method for writing Chinese character based on the smart-phone device. In order to recognize Chinese characters, first, a standard sample character is recognized. Because it is a font, it is necessary to make the size and shape constant regardless of the font or the form. The next step is to recognize the user-created image and compare it with the criteria. After the comparison, it is a process of evaluating how the reference value is similar to the value created by the user. After going through three steps, we compare the reference value with the user's writing. In this study, among the existing recognition methods, DP matching and HMM methods that are easy to apply to applications and proposed algorithms that combine DP matching with HMM. The proposed algorithm has resulted in a higher recognition rate of at least 1.05% compared to the previous recognition method.
