The study of improved binarization algorithm and the design of fingerprint identification system

1 Abstract. Many domestic enterprises use punch machine for attendance management of coal mine workers, which leads to have some underground hidden danger and have difficulties to confirm the accident personnel and rescue them afterwards. This paper describes the design of a fingerprint recognition system for coal mine workers identity recognition, which can guarantee the safe production. The result of debugging shows that this system can operate stably and reliably, improving the accuracy and efficiency of the security check.
