Image and Video Processing

The image and video processing group at LCAV performs research and education across the full image acquisition, processing and visualization chain. This holistic view relies on the mathematical foundations of analysis and synthesis, which are at the heart of all signal processing.

The group has a number of ongoing collaborations with academia, industry and cultural institutions, including GALATEA, ARTMYN and the Musée de l’Elysée.

Specific research areas include

  • Image and scene modelling
  • Reflectance function acquisition
  • Interference photography
  • Multi-view imaging
  • Augmented reality
