Answer: happy to consider dedicated NFIQ 2.0 for swipe sensors when sufficient 

data becomes available. 

Discussion topics at the workshop 

• NFIQ 2.0 for images captured by non-optical sensors 

• Such as swipe sensors used by mobile phones 

•

• NFIQ 2.0 for AFIS systems 

• Can NFIQ 2.0 predict performance of finger image / latent comparison when it is 

developed for finger / finger comparison? 

• Answer: Calibration – expected error rate of quality levels will be different but 

order will stay the same. 

• Revision of ISO/IEC 29794-1 to include confidence intervals? 

• Computational expense 

• Will be considered, but have not evaluated yet 

• But when features are optimized for speed, they will most probably change. 

• Strive for ~125-150 msec 

• Are matlab codes implementation available? Yes. 

• Inclusion of fingerprint-ness in NFIQ 2.0 – it is liveness issue and not 

quality? Is it already included in NFIQ 2.0?

Standardized Feature?

Vector of quality components 

≫ Revision of ISO/IEC 29794‐4 

≫ Follow the Part 6 (iris quality) 

model 

- For each quality component: 

Specify definiUon (what it is),

computaUon method, 

measurement unit, 

threshold/valid range 

Allows for
