AN ANALYSIS METHOD OF LETTER LIGATURE STROKES BASED ON CHARACTERS HANDWRITING TEACHING
摘要
Abstract
Intelligent guidance of letter ligatures is an important research content of characters handwriting tutoring system.The stroke structures of letter ligatures are complicated and changeable,the analysis method of single letter handwriting chirography can’t be directly set for letter ligatures strokes analysis.Aiming at this status quo,in this paper we propose a method of letter ligature strokes analysis,which is based on stroke-segmentation of key points in diagram-temporal domain.It is consisted of the following techniques:to extract key points from diagram and temporal domains respectively;to integrate the key points in two domains,according to three kinds of standard curved stroke seg-ments such as quadratic curve etc.to divide the stroke segments in vectors of key points in two domains;to set up stroke segments coefficient vector template by fitting with three kinds of standard curves;to realise the ligature strokes analysis according to the closeness of the fitting curves reconstructed by the various key points of actual handwritten strokes and the coefficient vectors.Experiment demonstrates that the im-portant indexes of the proposed method,including key points error pen-lifting rate,stroke segments error pen-lifting rate,real-time tracking time and closeness,etc.,all satisfy the practical requirement.关键词
