Applications of thermal image and extension theory to biometric personal recognition

摘要

In this paper, a new scheme is proposed to design a biometric personal recognition system. First, this paper used the thermal image of the hand by using infrared camera to build the sensor module of the recognition system; the extraction features include the length of palmar midpoint to each finger, palmar profile, finger length and finger width. The thermal image presented in this paper was detects infrared energy and converts it into an electronic signal. Then a new recognition method based on the extension is proposed to perform the core of the personal recognition system. The experimental results confirmed that proposed recognition system has a very high recognition rates, therefore, this paper verification using thermal image of the hand to identity recognition was feasible.
