Two Plane Volumetric Display for Simultaneous Independent Images at Multiple Depths
We propose a new projection system to visualise different independent images simultaneously on planes placed at different depths within a volume using multiple projectors. This is currently not possible with t...

Tissue Shape Acquisition with a Hybrid Structured Light and Photometric Stereo Endoscopic System
In situ 3D reconstruction from endoscopic images is important to determine the correct course of action for, e.g., treatment of abnormal growths. Currently, the endoscopist has to rely solely on visual c...
