Design of Fingerprint Acquisition System and Research on Image Pretreatment

A fingerprint acquisition system is designed,which is based on DSP,it's realized by MBF200,EZ-USB FX2 ICs and TMS320VC5402 which processes the image.The system completes the hardware and software system design,and also realizes the hardware and software debug of the USB and PC communications.The results show that the system is simple,feasible and practical.
