Abstract:

Biometric identification was a kind of identity recognition technology by making use of the human’s unique physiological or behavioral characteristics, it provided a high reliability and stability way for the identification. Global threshold binarization palmprint image is used in this paper, and the bio-morphological methods are used to get the sensitive area of palmprint image’s positioning point, so as to extract the region of interest. The palmprint collection is realized on the FPGA chip, and this kind of collection method uses the DSP Builder toolbox to realize visual programming in Matlab/Simulink and achieve fast modeling and development. The practice proves that this method is simple, flexible and its equipment is portable and fast.

Key words:  DSP builder  FPGA  palmprint identification  region of interest(ROI)
