    Read the biometric fingerprint time clock

    Read the biometric fingerprint time clock , extracting features, save data and comparison. In the beginning, through the fingerprint read equipment read human fingerprint image, take to the fingerprint image after, to original image carries on the preliminary processing, make it more clearly. Next, fingerprint recognition software to establish fingerprint digital representation - characteristic data, a kind of single direction of the conversion, can convert from fingerprint feature data but not from feature data conversion become fingerprint, and two pieces of different fingerprint will not produce the same feature data. Some new nodes and direction information combination produced more data, the direction information shows that the relationship between each node, and some algorithm also d
