VC5509A Based Fingerprint Identification Preprocessing System

摘要：

Automated fingerprint Identification is a method to identify a person based on his fingerprint physiological characteristics.Along with the rapid development of fingerprint identification technique and its broad applications,preprocessing algorithm is becoming a significant subject.In this paper,we present an automatic fingerprint acquisition and preprocessing system with a fixed point DSP,TMS320VC5509A and a fingerprint sensor,MBF200.The system is diminutive and flexible.We study preprocessing algorithms including filtering,enhancement,binarization,and thinning.By comparing different algorithms,a best one is selected.The system is implemented with C on the C55X platform.
