Visual Detection of Personal Protective Equipment and Safety Gear on Industry Workers
Jonathan Karlsson, Fredrik Strand, Josef Bigun +3
Workplace injuries are common in today's society due to a lack of adequately worn safety equipment. A system that only admits appropriately equipped personnel can be created to imp…
Periocular Biometrics: A Modality for Unconstrained Scenarios
Fernando Alonso-Fernandez, Josef Bigun, Julian Fierrez +3
Periocular refers to the externally visible region of the face that surrounds the eye socket. This feature-rich area can provide accurate identification in unconstrained or uncoope…
Fingerprint Image-Quality Estimation and its Application to Multialgorithm Verification
Hartwig Fronthaler, Klaus Kollreider, Josef Bigun +4
Signal-quality awareness has been found to increase recognition rates and to support decisions in multisensor environments significantly. Nevertheless, automatic quality assessment…
Near-infrared and visible-light periocular recognition with Gabor features using frequency-adaptive automatic eye detection
Fernando Alonso-Fernandez, Josef Bigun
Periocular recognition has gained attention recently due to demands of increased robustness of face or iris in less controlled scenarios. We present a new system for eye detection…
Experimental analysis regarding the influence of iris segmentation on the recognition rate
Heinz Hofbauer, Fernando Alonso-Fernandez, Josef Bigun +1
In this study the authors will look at the detection and segmentation of the iris and its influence on the overall performance of the iris-biometric tool chain. The authors will ex…
Real-time AdaBoost cascade face tracker based on likelihood map and optical flow
Andreas Ranftl, Fernando Alonso-Fernandez, Stefan Karlsson +1
The authors present a novel face tracking approach where optical flow information is incorporated into a modified version of the Viola Jones detection algorithm. In the original al…
