Joint object recognition and pose estimation is an important task in robotics applications and in automated manufacturing environments. In past work we established fast algorithms for the detection of rigid objects in cluttered point cloud data, and non-rigid human body shape estimation from range camera depth.
In collaboration with CRL’s Speech Technology Group we produced a complete system for expressive visual text-to-speech. Our system is able to producing expressive verbal and visual output in the form of a 'talking head', given an input text and a set of continuous expression weights.
Automated change detection is very valuable for inspection and maintenance. We conducted fundamental vision research to facilitate low cost change detection systems. Specifically, by combining 3D modelling with image registration, we compare images from different time instances and visually enhance change.
In 2007, CVG extended 3D reconstruction techniques and applied them to faces and the human body in motion. Here, CVG has created a computer vision technique using multiple cameras and three lights of different colours to capture deforming surfaces at high levels of detail.
Building 3D models of static scenes needs to be very accurate to be usable, for example, to create 3D prints of object. We developed multi-view geometry techniques to reconstruct a 3D shape at high precision.
