Vein recognition system based on DSP

A design method of vein recognition system based on ADSP-BF533 is proposed.The system is composed by two function module groups: the vein image acquisition modules and the vein image processing and recognition modules.The vein images are acquired through a black-and-white analog camera under the illumination of near-infrared LEDs.The central unit for vein image processing and recognition is a Blackfin 533 DSP made by ADI(ADSP-BF533),whose work frequency is fast enough to relize the processing and recognition function.Experimental results show that the system is definitely suitable for embedded vein recognition.
