We propose an on-line writer recognition method for Thai numeral based on barycenter trajectory and handwriting velocity. A barycenter of triangle composed of the origin and the two adjacent points of pen-point positions (BCTP) is used effectively to extract the feature of handwriting instead of the pen-point position. Using BCTP, the velocity of handwriting process is estimated. We incorporate the velocity of handwriting process and the BCTP trajectory in this paper. Writer is recognized by using dynamic programming (DP) matching. Writer recognition experiments were performed by using 4,100 data collected by 10 Thai writers for one year. As the results, the average of Type I (false rejection)error rate and Type II (false acceptance)error rate were 9.15% and 4.12%, respectively.
