| Abstract(in English) | We propose a method of generating a high quality dictionary from learning handwritten samples, for an online character recognizer which uses a time sequence of characteristic points as a dictionary template. Our method consists of two phases. In the first phase, we decide the optimal number of clusters by generating clusters using LBG, and generate the average template from each cluster by applying an elastic pattern matching algorithm. In the second phase, each average template is adjusted by a kind of LVQ to avoid miss-recognition between similar categories. In our experiment, the recognition accuracy improves about 2% while dictionary size increases little from 157KB to 166KB. Especially, the improvement is noticeable for small-stroke-categories. |
