Aureus 3D FR version 2.0
®
Aureus 3D 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.
Aureus 3D FR is robust against:
Pose: 60o yaw, 20o pitch and 30o roll automatically, (360o roll with manual initialization).
Large expression changes
Partial Face Occlusion
Facial hair
Glasses
Lighting changes (excluding strong shadows)
Template specifications:
Size = 1200 bytes
Generation time = 240ms using 3.0GHz CPU
Match time = 0.8 micro seconds (1.25 million matches per second on single 3GHz CPU core).
Template generation and matching are re-entrant thread safe.
Minimum image specifications:
Face size (from chin to top of head) 90 pixels. This is roughly equivalent to a 30 pixel inter eye
distance in a front facing image.
Grayscale dynamic range of 32 or more within face.
Input image via function, can be grayscale, RGB, BRG, RGBA, BGRA with origin bottom left or top left.
Usage:
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.
Simple to use: (1) Load (2) Initialize once (3) call “GetTemplate” and “MatchTemplates”
Biometric Performance:
All tests performed using the color FERET dataset (http://www.nist.gov/itl/iad/ig/colorferet.cfm).
Two frontal sets of images were used comprising 8,232 images* of 965 different people (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).
Minimum Host System:
64 bit Windows 7, Windows 8, Server 2008 R2, Server 2012
4 Gb RAM
1 Gb disk space for application installation

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).
