Aureus FR

The Aureus 3D Face Recognition Engine

Aureus FR uses the Aureus 3D pose correction algorithms under the hood without the need for a graphics card. It can handle large head pose, large expression changes and most lighting changes. It is re-entrant thread safe and can match more than a million templates per second on a single CPU.


It has a simple C style interface that can be called from any language capable of interfacing with the standard C bindings such as C, C++, C#, JAVA, Python, etc.
Biometric Performance:

All tests performed using the color FERET dataset ( Two frontal sets of images were used (set “fa” and “fb”) and eight non frontal sets were used (hl, hr, ql, qr, ra, rb, rc, rd) containing large head yaw (up to 70 degrees).
Simple to use: (1) Load (2) Initialize once (3) call “GetTemplate” and “MatchTemplates”

Rank Test:
A rank test was performed in which the gallery was made from the two frontal sets and the probes from the remainder.













ROC Test:
A similarity matrix was constructed in which every image was matched to every image and the results stored in a similarity matrix. The values along the diagonal of the matrix were the results of matching the images to themselves, they were therefore omitted from the ROC results. True Positives (TP), True Negatives (TN), False Positives (FP) and False Negatives (FN) were counted for a thousand different thresholds ranging from zero to unity. True Positive Rate (TPR) was calculated as TP/(TP+FN) and False Positive Rate was calculated as FP/(FP+TN).
