Research Themes

Markerless Motion Capture (2008)

The project aims to infer the poses of a character acting in a environment filmed by a set of video cameras. Once the poses are estimated, a free-viewpoint video of the entire action is genertated. (read more...)

Passive 3D reconstruction (2006)

The project aims to automatically infer the shape of a static object from a set of pictures. The challenge is to use different shape cues together in a single minimization procedure to increase the accuracy of the shape estimation. In particular, in this project, the stereo cue is used together with the silhouettes and shadows cues. The reconstruction pipeline is the following: Once the shape is estimated, its texture is recovered using a pyramidal blending technique based on wavelets. Some examples follows:

Frog model [WRL]
(silhouette + texture)

Cube model [WRL]
(silhouette + texture + shadow)

Statue model [WRL]
(silhouette + texture)

Asteroid shape analysis (2007)

Motion recovery and 3D reconstruction of the asteroids Steins and Lutetia observed by the Rosetta spacecraft during its journey started in 2004.
