Best Poster Paper Award for Marcel Grimmer et al. at BIOSIG 2022

Marcel Grimmer, Haoyu Zhang, Raghavendra Ramachandra, Kiran Raja, Christoph Busch received the best poster paper award for the contribution of „Time flies by: Analyzing the Impact of Face Ageing on the Recognition Performance with Synthetic Data “ at the 21st International Conference of the Biometrics Special Interest Group (BIOSIG 2022), which took place in Darmstadt, Germany.


The vast progress in synthetic image synthesis enables the generation of facial images in
high resolution and photorealism. In biometric applications, the main motivation for using synthetic
data is to solve the shortage of publicly-available biometric data while reducing privacy risks when
processing such sensitive information. These advantages are exploited in this work by simulating
human face ageing with recent face age modification algorithms to generate mated samples, thereby
studying the impact of ageing on the performance of an open-source biometric recognition system.
Further, a real dataset is used to evaluate the effects of short-term ageing, comparing the biometric
performance to the synthetic domain. The main findings indicate that short-term ageing in the range
of 1-5 years has only minor effects on the general recognition performance. However, the correct
verification of mated faces with long-term age differences beyond 20 years poses still a significant
challenge and requires further investigation.
