WANG Feng1, CHEN Yun1. Research on improved method for different type of fingerprint sensors matching performance[J]. 2010, 29(1): 65-68. DOI: 10.13873/j.1000-97872010.01.027.
The specifications of fingerprint sensor are diverse
the principle and design are different
and one product is incompatible with other products
which led to system matching performance of different types of sensors reduced greatly.An approach combined two common types of fingerprint sensors(optical and capacitive sensors) is presented to improve system matching performance.Two images are captured from two types of sensors respectively.After the pre-processing program extracted detail point match the template fingerprint
and the two matching scores are obtained
and then final score is obtained from fusion of two matching scores.Compared with single sensor matching performance
fusion result has greatly improved the performance of the system.
