Realization of fingerprint identification on DSP

Abstract

Along with the rapid development of biometric identification techniques, the fingerprint identification is becoming a significant subject. Automated fingerprint identification is a method to identify a person based on his fingerprint physiological characteristics. This paper presents an automatic fingerprint capture and preprocessing system with a fixed point DSP, TMS320VC5510A and a fingerprint sensor, FPC1011C. This system supplies two types of power: 1) wall adapter power, which can automatically switch from the wall adapter power to the battery in case of power-fail or brownout conditions, and 2) battery . With the interactive module , keyboard and the LCD in this system, the algorithm can run smoothly to realize the fingerprint processing. © Springer-Verlag 2009.
