Fingertip Detection Approach for Finger-Writing Chinese Character Recognition System

Yang Duan-duan Jin Lian-wen Yin Jun-xun (School of Electronic and Information Engineering,South China Univ.of Tech.,Guangzhou 510640,Guangdong,China)  
In order to meet the requirements of finger-computer interaction system,a fast robust fingertip detection method is proposed.In this method,first,the foreground is segmented to obtain the contour of the hand.Next,a candidate area is identified as the rough position of the fingertip by means of the grid sampling.Then,the accurate position of the fingertip is determined by means of the circle feature matching,reaching an accuracy of 98.5%.Finally,the proposed fingertip detection method is applied to a finger-writing Chinese character recognition system,in which the computer can directly recognize the characters written by the fingers of a user.
