Anika Pflug graduated

Anika Pflug defended her doctoral thesis in Information Security at Gjøvik University College (GUC) on Friday 19th of June. Pflug is associated to NISlab (Norwegian Information Security laboratory) at Gjøvik University College. The dissertation is titled “Biometric Identification using 2- and 3- Dimensional Images of Human Ears”.

The outer ear is an emerging biometric trait disputas_anika_pflueg_2that has drawn the attention of the research community for more than a decade. The unique structure of the auricle is long known among forensic scientists and has been used for the identification of suspects in many cases. The next logical step towards a broader application of ear biometrics is to create automatic ear recognition systems.

This work focuses on the usage of texture (2D) and depth (3D) data for improving the performance of ear recognition. It compares ear recognition systems using either texture or depth data with respect to segmentation and recognition accuracy, but also in the context of robustness to pose variations, signal degradation and throughput.

The proposed ear recognition system is integrated into a demonstrator system as a part of a novel identification system for forensics. The system is benchmarked against a number of different datasets that comprise of 3D head models, mugshots and CCTV videos from four different perspectives. As a result of this work, limitations of current ear recognition systems are outlined and possible directions for future applied research are provided.
