Depth Imaging

Since 2007 we are working on depth imaging. We combine the depth images from either time-of-flight or stereo cameras with color images. We aim on not just gathering depth information from these systems alone or by fusing them, but also visualize the depth information directly. This includes augmented reality scenarios as well as image or video manipulation.

We offered several courses about this research topic. See the webpages of the projects for details.
