Marker-less Motion Capture
In this project, we develop statistical and energy minimization methods to tracking articulated 3D objects from multiple camera views. Such techniques are of central importance in particular for markerless motion capture. The human motion sequence extracted from multiple videos can subsequently be used to animate virtual characters as commonly done in action movies.
