In this paper we provide preliminary results on a new modeling approach for improved determination of facial expressions from a low-resolution video stream. An initial proof-of-concept using an extension of an Active ...

A real-time stereo imaging system is described. It incorporates dual image acquisition chains on a single FPGA device and is able to provide real-time synchronized video output from twin CMOS imaging sensors. The platform ...

An innovative micropayment solution is proposed which incorporates both distributed security and social networking features. This has significant potential to impact on both the provision of new services and community ...

Making use of a class of 2D statistical face models known as active appearance models (AAMs), we investigate a technique for generating real-time animated avatars suitable for video gaming. We consider here a number of ...

Techniques for improved 2D active appearance face models are presented. When these are applied to stereoscopic image pairs we show that sufficient information on image depth is obtained to generate an approximate 3D face ...
