120 Mbps Mobile WiMAX Scalable OFDMA Signal Transmission over RoF with SMF, DCF and Chirped FBG for Fibre Length of 792 km
Wireless and Mobile Communications, International Conference on
By Mazin Al-Noor, Kok-Keong Jonathan Loo, Richard Comley
Issue Date:September 2010
Fibre attenuation and chromatic dispersion are the most important problems that create slops, changes of the frequency spectrum. Therefore the signal can only be clearly transmitted over a limited distance. In order to increase the signal transmission dist...
Toward a Robust System to Monitor Head Motions during PET Based on Facial Landmark Detection: A New Approach
Computer-Based Medical Systems, IEEE Symposium on
By Sergey Anishchenko, Vladislav Osinov, Dmitry Shaposhnikov, Lubov Podlachikova, Richard Comley, Xiaohong W. Gao
Issue Date:June 2008
A new approach for the detection of head motions during PET scanning is presented. The proposed system includes 4 modules, which are: input module, face segmentation, facial landmark detection, and head movement estimation. The developed system is tested o...
A Hybrid Wavelet-Based Compression System
Information Technology and Applications, International Conference on
By Vooi Voon Yap, Richard Comley
Issue Date:July 2005
The recent trend in picture messaging via mobile devices is producing a new demand for highly effective colour image compression. Current techniques favour wavelet filters that process the image as a whole. While this offers many advantages, it can lead to...
