Face DatabasesCurrent databases (CMU PIE,

FRGC/FRVT, FERET)Short rangeIndoorsArtificial Light

Only one known attempt at creating long range outdoor database

CMU PIE small but very controlled datasetFERET , FRGC/FRVT large but sacrifice controlWe need more databases to further face

recognition

Why Synthetic?• Long term cost is cheaper(still costly

so this is not a deciding factor)• More experimental control• Explore more conditions • Can also be used to validate changes

in systems

Summary/ConclusionsCreated an end to end framework which is

validated to work with frontal posesScientifically validated that the models facing

forward are equivalent to human beings for ROI of face recognition

Shown how synthetic data takes out or controls many existing variables in facial recognition.

Recent publication in the upcoming AMFG workshop shows the biometric research community has interest in developing this technique further.
