6 Comparison to MINEX III

Minutia Exchange (MINEX) III is NIST’s ongoing test of interoperable fingerprint template generation and matching. The only data permitted to be stored in a MINEX-compliant template are minutia type (ridge ending, bifurcation, or unknown), angle, location, and quality, as well as finger position and image quality. PFT III templates have no restrictions on the contents of the template. The results shown in this section are computed based on the exact MINEX III dataset, but using the proprietary template generator and matcher from Tech5+0046.

Note that while TECH5 USA INC may be a participant in both PFT III and MINEX III (perhaps even with the same identifier of Tech5+0046), it does not indicate that the same underlying implementation was used. Information about equivalence of implementations should be addressed to the participant.

6.1 Single Finger

Figure Figure 6.1 and Table 6.1 show single finger results, which corresponds to Figure 2 and Table 4 from any MINEX III report card.

6.2 Two Finger

Figure 6.2 and Table 6.2 show combined two finger results (i.e., sum fusion of the single finger results), which correspond to Figure 7 and Table 7 from any MINEX III report card.

Detection error tradeoff of combined index fingers compared in the MINEX III evaluation.
