    • Cross-sensor periocular biometrics in a global pandemic: Comparative benchmark and novel multialgorithmic approach 

      Alonso-Fernandez, Fernando; Raja, Kiran; Ramachandra, Raghavendra; Busch, Christoph; Bigun, Josef; Vera-Rodriguez, Ruben; Fierrez, Julian (Peer reviewed; Journal article, 2022)
      The massive availability of cameras and personal devices results in a wide variability between imaging conditions, producing large intra-class variations and a significant performance drop if images from heterogeneous ...

    • Differential Privacy Preservation in Robust Continual Learning 

      Hassanpour, Ahmad; Moradikia, Majid; Yang, Bian; Abdelhadi, Ahmed; Busch, Christoph; Fierrez, Julian (Peer reviewed; Journal article, 2022)
      Enhancing the privacy of machine learning (ML) algorithms has become crucial with the presence of different types of attacks on AI applications. Continual learning (CL) is a branch of ML with the aim of learning a set of ...

    • E2F-GAN: Eyes-to-Face Inpainting via Edge-Aware Coarse-to-Fine GANs 

      Hassanpour, Ahmad; Daryani, Amir Etefaghi; Mirmahdi, Mahdieh; Raja, Kiran; Yang, Bian; Busch, Christoph; Fierrez, Julian (Peer reviewed; Journal article, 2022)
      Face inpainting is a challenging task aiming to fill the damaged or masked regions in face images with plausibly synthesized contents. Based on the given information, the reconstructed regions should look realistic and ...
