We present a technique which allows capture of 3D surface geometry and a useful class of BRDFs using extremely simple equipment. A standard digital camera with an attached flash serves as a portable… (More)
Accurate and reliable tracking of the 3D position of human heads is a continuing research problem in computer vision. This paper addresses the specific problem of model-based tracking with a generic… (More)
The simultaneous isomorphous substitution of Al(III) and P(V) ions, in an aluminophosphate framework, with redox active Co(III) and Ti(IV) metal ions, generates highly active single-site… (More)
Accurate, realistic and efficient rendering of human faces is of great importance in graphics applications. For high-speed rendering, a low-fidelity 3D model may be effectively enhanced by the use of… (More)
