3D shape and its applications

Summary form only given. The talk will begin with an overview of the state-of-the-art in the 3R´s of computer vision: registration, reconstruction and recognition and will include demonstrations of research which has been recently commercialised at Cambrdige (Zappar, Metail, Toshiba gesture interfaces and Microsoft Kinect). This will be followed by a review of more advanced techniques in multi-view stereo and photometric stereo for recovering accurate and complete 3D models from uncalibrated images. I will then look in more detail at techniques for recovering the shape of deforming objects such as the human body and face and the challenges of large scale reconstruction of outdoor scenes and the application to ageing infrastructure.
