• Deep Composite Face Image Attacks: Generation, Vulnerability and Detection 

      Singh, Jag Mohan; Ramachandra, Raghavendra (Peer reviewed; Journal article, 2023)
      Face manipulation attacks have drawn the attention of biometric researchers because of their vulnerability to Face Recognition Systems (FRS). This paper proposes a novel scheme to generate Composite Face Image Attacks ...
    • Fingerphoto Verification Using Siamese Neural Network 

      Madhun, Ahmed Said Mahmoud (Master thesis, 2020)
      De siste årene har vi hatt en enorm utvikling av portable enheter. Sensorene i smart-telefoner og bærbare datamaskiner har kommet til det stadiet at de åpner for nye former for biometrisk autentisering. En av disse formene ...
    • Hessian-based Robust Ray-Tracing of Implicit Surfaces on GPU 

      Singh, Jag Mohan; Wasnik, Pankaj Shivdayal; Ramachandra, Raghavendra (Chapter, 2018)
      In recent years, the Ray Tracing of Implicit Surfaces on a GPU has been studied by many researchers. However, the existing methods have challenges that mainly includes solving for self-intersecting surfaces. General solutions ...
    • Morphing Attack Detection-Database, Evaluation Platform, and Benchmarking 

      Raja, Kiran; Ferrara, Matteo; Franco, Annalisa; Spreeuwers, Luuk; Batskos, Ilias; Wit, Florens de; Gomez-Barrero, Marta; Scherhag, Ulrich; Fischer, Daniel; Venkatesh, Sushma; Singh, Jag Mohan; Li, Guoqiang; Bergeron, Loïc; Isadskiy, Sergey; Ramachandra, Raghavendra; Rathgeb, Christian; Frings, Dinusha; Seidel, Uwe; Knopjes, Fons; Veldhuis, Raymond N.J.; Maltoni, Davide; Busch, Christoph (Peer reviewed; Journal article, 2021)
      Morphing attacks have posed a severe threat to Face Recognition System (FRS). Despite the number of advancements reported in recent works, we note serious open issues such as independent benchmarking, generalizability ...
