Abstract :
A Gabor wavelet based palmprint recognition algorithm is introduced in this paper. With high recognition rate and low computational complexity, the algorithm is suitable for portable platform. TI TMS320VC5509A is a high performance digital signal processor (DSP) provided by Texas Instruments Corporation. By using the 5509A chip as the core processor, working with AVR microcontroller, CPLD device and CMOS image sensor, the hardware platform is constructed. By porting the recognition algorithm to the hardware platform, a portable palmprint recognition system is proposed in this paper. Experimental results on PolyU palmprint database and actual captured palmprint image database have demonstrated that, the implemented recognition system can indicate palmprints effectively with little computation time and chip resources required.
