10. A character recognition system comprising: a processing unit; a memory coupled to the processing unit; a feature extraction module implemented at least in part by the processing unit to recognize a handwritten East Asian character by using a Hidden Markov Model (HMM) and to extract features from ink data of the handwritten East Asian character, the features being extracted comprising at least one of a tangent feature, a curvature feature, a local length feature, a connection point feature, or an imaginary stroke feature.

The system of claim 10 , further comprising: an acquisition module implemented at least in part by the processing unit to uniformly sample the ink data; and a frame module implemented at least in part by the processing unit to analyze the features of the ink data by breaking the ink data into frames.
