Abstract

A DSP-based design method of finger vein recognition was proposed, and a finger vein authentication system FV-1 was developed. In this system, finger vein images were captured with infrared, and normalized through rotation correction, then they were segmented and thinned to wipe off useless segments. Finally, features on vein points were obtained and two finger vein images were matched in view of a feature distance. All these processes were completed with the high performance DSP called DM6437 of TI Corporation. The system is small and the recognition rate is good with the high matching speed.
