Abstract(in English) | A new hidden Markov model (HMM) is proposed to represent character strokes of on-line handwriting patterns. The proposed HMM deals with two typical features describing strokes, pen-direction feature and pen-coordinate feature. These two features are quite different in their stationarity; the pen-direction feature is stationary within every line segment of strokes whereas the pen-coordinate feature is not. To deal with these contrasting features by a single HMM, they are used selectively in the HMM. Specifically speaking, the pen-direction feature is output repeatedly at the intra-state transition whereas the pen-coordinate feature is output once at the inter-state transition. The usefulness of the proposed HMM over the conventional HMMs were shown through stroke order-free Chinese character recognition experiments. |
