A combined approach to feature extraction for mouth characterization and tracking
A statistical Active Appearance Model (AAM) is developed to model and track the lips. A major challenge in modelling the mouth area, considered the most deformable facial feature, is the weak contrast between lips and skin ...
Facial expression modeling using component AAM models - Gaming applications
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 ...
FPGA based stereo imaging system with applications in computer gaming
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 ...
A secure and efficient micropayment solution for online gaming
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 ...
Appearance capturing and animation techniques for realistic, true-identity gaming avatars
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 ...
Enhanced real-time face models from stereo imaging for gaming applications
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 ...
