    Analyzing Growing Plants from 4D Point Cloud Data

    We introduce a framework to analyse time-lapse 3D scan of growing plants, particularly focusing on accurate localization and tracking topological events like budding and bifurcation. We evaluate our approach on multiple data sets and use the results to animate static virtual plants or directly attach them to physical simulators.

    Reconstructing Detailed Dynamic Face Geometry from Monocular Video

    We present a method for capturing face geometry from monocular video. It works under uncontrolled lighting and successfully reconstructs expressive motion including high-frequency face detail. After simple manual initialization, the capturing process is fully automatic. We demonstrate performance capture results for long and complex sequences captured indoors and outdoors.

    Inverse Dynamic Hair Modeling with Frictional Contact

    We present a method for converting a hair geometry into a physics-based hair model, such that the static hair pose, in the presence of gravity and frictional contact, accurately matches the input geometry. Our method was used to animate both artistic hairstyles and recent hair data reconstructed from capture.

    On-Set Performance Capture of Multiple Actors With A Stereo Camera

    We describe a new method which is able to track skeletal motion and detailed surface geometry of one ore more actors from footage recorded with a stereo rig that is allowed to move. It succeeds in general sets with uncontrolled background and uncontrolled illumination.
