Investigation of using pen-coordinate and pen-directive features by HMM in the online character recognition

Abstract (in Japanese) (See Japanese page) 
(in English) A new hidden Markov model (HMM) is proposed to represent strokes of
on-line character. 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;
pen-direction feature is stationary within a line segment of stroke
whereas pen-coordinate feature is not. To deal with these contrasting features by a single HMM, pen-direction feature is outputted repeatedly
at intra-state transition whereas pen-coordinate feature is outputted
once at inter-state transition. The usefulness of the proposed HMM over
the conventional HMMs were shown through stroke-order free and stroke-order fixed character recognition experiments.
