Time and timing issues within the wireless application home environment
Hardware implementation of a real-time 3D video acquisition system
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. ...
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 ...
Fast A/V channel switching on a wireless home network
A method of enabling fast switching between multimedia streams on an 802.11g network is described. This technique is particularly useful for A/V home network applications where it is desirable to simulate the fast channel ...
Automatic indexing of consumer image collections using person recognition techniques
An evaluation of person recognition technologies for use in an automatic cataloging tool for consumer image collections is presented. Prototype implementations of the automatic cataloging tool and user search tools are ...
Home networking middleware infrastructure for improved audio/video appliance functionality and interoperability
A software architecture is described which significantly improves the accessability of multiple home appliances on a heterogeneous home network. Methods for aggregating devices into virtual clusters on a local middleware ...
Rapid prototyping of networked A/V CE appliances
In this paper the design and rapid prototyping of networked A/V CE appliances is described. Practical implementations of three types of appliance are described: (i) a streaming A/V server; (ii) a streaming A/V client device ...
Biometrically auditable public key infrastructure technology for secure multimedia content
A system for signing and tracing the use of digital content based on biometrically generated key-pairs is described. The system is designed to protect the fair use rights of end-users and can be readily incorporated into ...
