A combined approach to feature extraction for mouth characterization and tracking
(IEEE, 2009-02-10)
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
(IEEE, 2009-10-23)
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
(IEEE, 2009-10-23)
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 ...
Architecture for a Home Media Network Based on PTP-IP Connectivity Techniques
(IEEE, 2008-08-05)
PTP/IP functionality is extended to enable networked devices to be organized in a sequential media processing workflow. The additional device functionality necessary to support this network architecture is not unduly complex ...
Managing Digital Image Collections from your TV-Set: A State-of-Art Review
(IEEE, 2007-07-14)
The problem of managing growing digital image collections is discussed in the context of a home user. The use of a conventional television set as both a viewing and management tool is discussed. The problem of linking ...
Hardware implementation of a real-time 3D video acquisition system
(IEEE, 2010-07-15)
An implementation of a real-time 3D video acquisition system on a single FPGA is presented. Our approach is based on the use of stereo image sensors and can display real-time 3D video when combined with shutter glasses. ...
Appearance capturing and animation techniques for realistic, true-identity gaming avatars
(IEEE, 2009-10-23)
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
(IEEE, 2009-10-23)
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 ...
Biometric access control for digital media streams in home networks
(IEEE, 2007)
Methods for controlling access to digital media content in the home environment using biometric sensing techniques are described. A wireless rebroadcast system for IP-TV content was retrofitted with a combination of ...
Architecture of a PVR appliance with 'Long Tail' internet-TV capabilities
(IEEE, 2006)
The design and implementation of a networked PVR appliance incorporating support for Internet-TV is described. The appliance incorporates support for the bittorrent protocol and employs user tools for content location, ...
