As part of the portfolio activity we will examine technologies that encompass enhancing existing technologies in areas such as 3G and develop new technologies for 4G. Immersive presence and virtual remote collaboration systems will be the areas focused on for the mid-to long-term research. The navigation and interaction with information over the fixed and more importantly wireless networks, including the Internet will be a key part of this programme. This will help to make the man- machine interface a more enjoyable experience. Some of the key activities are as follows: An IPv6 wireless test-bed for applications in PAN with service discovery and context aware issues PAN and BAN using ultra wide band (UWB) communications Advance audio-visual processing for 3D capturing, rendering and interaction Acoustic modelling and synthesis Video content adaptation using transcoding and link adaptation for improved quality of service (QoS) Highly scalable model based coding for low rate video transmission Multi-modal interfaces and human computer interaction Wireless sensors based human motion capture and tracking Example of transmitted video quality improvements possible with wireless link adaptation techniques Content adaptation by transcoding: Combined rate adaptation and error resilience insertion for transmission over UMTS. 445128kb/s error-free transcoded 445128kb/s non-resilient transcoded 445128kb/s error-resilient transcoded INTEGRATED ELECTRONICS PORTFOLIO PARTNERSHIP "Our overall vision is to drive forward science and technology at the component and sub-system level, informed by system level solutions to commercial applications, with the ultimate goal of improving the health, wealth and vitality of humankind in the era of all-pervading personal information exchange".

3D Data Analysis and Object Representation
Starting from 2D or 3D image data we construct finite element models of 3D objects, with applications in Medicine and Industry. We are using dynamic programming and optimisation techniques for constructing models from volume or surface data. We have already applied these techniques to extract all seismic horizons simultaneously from seismic data.A Blinov and M Petrou. “Horizon extraction from 3D seismic data” IEEE Transactions on Geoscience and Remote Sensing, June 2005.
