Real time detection and tracking of faces and face features.

Invented the most robust and accurate geometric camera calibration algorithm, a cornerstone of precise image-based measurements. Very high accuracy was achieved (0.002 pixel RMS error) while simultaneously exhibiting an exceptionally high robustness to noise, compression and other artefacts. Also performed early pioneer work on dual-laser-line 3D reconstruction, which has is now a common commercially available tool for scanning 3D parts.

Design of a real-time face detection and tracking system for semi-controlled situations using a special 360-degrees cylindrical camera. A very high detection rate (>96% typ.) was reached while keeping the false positive rate at a negligible level (<0.1%). This was used downstream for the analysis of people's non-verbal activity during meetings.

Helped with the computer vision needs of the laboratory regarding geometric measurements of flows and sediments using cameras and laser sheet imaging. Keywords: laser ranging, camera calibration, machine vision, optics, photography, 1394/linux

The success of the project led to more EU funded projects for the laboratory.Invented a novel road-side traffic monitoring system using high-speed line-scan cameras. This technique allows numerous measurements from a single sensor: speed, acceleration, size and even inter-vehicle distances. Accuracy suitable for law-enforcement applications.Study of a mixed reality system within the ALIVE / Art.Live project, which led to the establishment of the Alterface company. Helped Alterface during its inception. Various consulting works for them in real-time computer vision, camera control, image acquisition and augmented reality.Design of a structure-from-motion system for road monitoring applications within the MODEST project. Responsible for camera calibration, 3D reconstruction (matching,...) and daily project management. Show less

Participated in the founding of Alterface, a startup of the Université catholique de Louvain’s Telecom Laboratory which pioneered augmented reality and mixed reality interaction back in the early 2000’s. Contributions to the company’s computer vision code base included real time image processing, segmentation, MMX/SSE optimizations, as well as camera capture and control. Regular participation in demonstrations and customer installations across Europe.
