Detecting lenses of the same brand

as used in the training data is easy.

Detecting brands of lenses not seen

in the training data is more difficult,

can have highly variable results.

Doyle (IEEE Access, 2015) shows

that more brands in the training data

improves generalization.

The scores are NOT from 1:N search.

They are from “1-to-First” search.

1:First versus 1:N detail –

The OPS-XING dataset used in IREX

VI has no independent ground truth.

15

GIS 2015 ADVANCED TECH RESEARCH. 9-24-2015.

The (assumed) authentic distribution is not close to Gaussian.

“truncated”

“censored”

16

GIS 2015 ADVANCED TECH RESEARCH. 9-24-2015.

The IREX VI regression analysis is

not matched to the properties of

the OPS-XING dataset.

17

GIS 2015 ADVANCED TECH RESEARCH. 9-24-2015.

Up-to-3-tries image acquisition

1st, 2nd, 3rd match distributions differ!

Should not be mixed in one regression.

(See paper by Czajka in BTAS 2015.)

The IREX VI OPS-XING dataset is a

composite of many data streams:

69 different kiosks.

11 different locations.

most with US and CA kiosks.

Toronto T1 and Vancouver are two

of the higher-traffic locations.

(See paper by Ortiz in Biometrics Workshop 2015.)

Would you fit a straight

line to this data?

Would you merge the two datasets, fit a line

to the merged data, and use that as your

best estimate of iris template aging?

How about this data?

Future.

21

GIS 2015 ADVANCED TECH RESEARCH. 9-24-2015.

Visible-light iris in some instances. (e.g., see Hugo Proenca’s work)

Better sensors, in an HCI sense.

Better segmentation, matching.

More nation-scale applications. (like Somaliland voter registration)

More on gender, race from iris

More research on iris aging.
