Computer Vision

The Centre for the Advanced Study of Collective Behaviour

Since March 2020, I have been working at the Centre for the Advanced Study of Collective Behaviour. Biologists, psychologists, computer scientists and many more disciplines interdisciplinary work together and study collective behaviour across a wide range of species and across scales of organization.

I am a computer scientist within the Computer Vision and Image Analysis group. We focus on multi-object tracking and pose estimation methods for animals. We acquire data in our imaging facilities – the Imaging Barn and the Imaging Hangar – which are located in Möggingen at the Max Planck Institute of Animal Behavior and in the Centre for Visual Computing of Collectives at the University of Konstanz respectively.
