Institut für Informationsverarbeitung (TNT)

Felix Kuhnke studied Media Technology at Technische Universität Ilmenau with a focus on Signal Processing. He wrote his master's thesis with the title "Implementation and evaluation of a real-time pitch range extension algorithm for cochlear implants" at the Fraunhofer Institut for Digital Media Technology and received his master's degree in 2014. Since May 2015 he is working as a research assistant at the Institut für Informationsverarbeitung (TNT) at Leibniz Universität Hannover.

In October 2017 he became the senior engineer ("Oberingenieur") of the Institut für Informationsverarbeitung, being responsible for internal and external representation of the institute (students, academic and industrial guests) as well as administrative and organizational tasks.

His main area of reasearch was analysis and synthesis of human faces, virtual avatars, and domain adaptation. In the FG2020 competition on Affective Behavior Analysis in-the-wild (ABAW) he and his colleagues have won the 1st place for emotion recognition.

His work also focused on application-related topics of computer vision for automated testing scenarios.

Research Interests:
