Overview
Fingerprint processing includes two parts:
fingerprint enrollment and fingerprint matching (the matching can be 1:1 or
1:N). When enrolling, user needs to enter the finger two times. The system will
process the two time finger images, generate a template of the finger based on
processing results and store the template. When matching, user enters the
finger through optical sensor and system will generate a template of the finger
and compare it with templates of the finger library. For 1:1 matching, system
will compare the live finger with specific template designated in the Module;
for 1:N matching, or searching, system will search the whole finger library for
the matching finger. In both circumstances, system will return the matching
result, success or failure.
