Forschungsinteressen

  • In general: computer vision algorithms, image and video processing, machine learning ("old school" as well as deep learning)
  • More specifically: human pose estimation with a focus on human pose analysis, kinematic and dynamic parameter prediction from pose estimates in video footage

Projekte

  • Swimmer detection and pose estimation for continuous stroke rate determination
  • Deep Ski-Jump Pose

      

Dissertation

Dan Zecha. Motion Kinematics and Dynamics Prediction Using Human Pose Estimation in Videos: Towards Automated Kinematical Profiling of Swimmers and Ski Jumpers.
Dissertation, University of Augsburg, July. 10, 2019.
