Abstract
This paper presents a realization of finite impulse response (FIR) system for on-line writer recognition. The FIR system is realized using Fourier coefficients of a barycenter of trajectory of pen-tip movement (BTP) and its velocity in handwriting process. The input and output of the FIR system are the Fourier coefficients of the velocity and the BTP, respectively. With the realized FIR system, writer can be recognized by comparing the output to the input for unknown writer with the reference output for a particular writer. Experimental results are given to show the effectiveness of the proposed method. In our experiments, FRR (false rejection rate) and FAR (false acceptance rate) were 1.50% and 0.65%, respectively.
