Synthetic ID Card Image Generation for Improving Presentation Attack Detection
Daniel Benalcazar, Juan E. Tapia, Sebastian Gonzalez +1
Currently, it is ever more common to access online services for activities which formerly required physical attendance. From banking operations to visa applications, a significant…
Towards an efficient Iris Recognition System on Embedded Devices
Daniel P. Benalcazar, Juan E. Tapia, Mauricio Vasquez +3
Iris Recognition (IR) is one of the market's most reliable and accurate biometric systems. Today, it is challenging to build NIR-capturing devices under the premise of hardware pri…
Impact of Face Image Quality Estimation on Presentation Attack Detection
Carlos Aravena, Diego Pasmino, Juan E. Tapia +1
Non-referential face image quality assessment methods have gained popularity as a pre-filtering step on face recognition systems. In most of them, the quality score is usually desi…
Learning to Predict Fitness for Duty using Near Infrared Periocular Iris Images
Juan Tapia, Daniel Benalcazar, Andres Valenzuela +3
This research proposes a new database and method to detect the reduction of alertness conditions due to alcohol, drug consumption and sleepiness deprivation from Near-Infra-Red (NI…
Alcohol Consumption Detection from Periocular NIR Images Using Capsule Network
Juan Tapia, Enrique Lopez Droguett, Christoph Busch
This research proposes a method to detect alcohol consumption from Near-Infra-Red (NIR) periocular eye images. The study focuses on determining the effect of external factors such…
Single Morphing Attack Detection using Siamese Network and Few-shot Learning
Juan Tapia, Daniel Schulz, Christoph Busch
Face morphing attack detection is challenging and presents a concrete and severe threat for face verification systems. Reliable detection mechanisms for such attacks, which have be…
