Ad hoc Networking, Markov Random Fields, and Decision Making
(2006)Our central proposition is that by articulating decision making in an ad hoc network using a Markov random field (MRF) maximum a posteriori (MAP) approach, a viable decision- making framework can be designed. This ... -
Applications and Opportunities for Cognitive Radio and Networks
(IEEE, 2012-07)we present three aspects of cognitive radio and networks of importance to the research and commercial development community. We firstly outline key emerging application areas for CR/geo-location. Secondly, we look how the ... -
Automated treatment of film tear in degraded archived media
(IEEE, 2004)A common form of degradation in archived film is film tear. This is caused by the physical ripping of the film. Tear causes displacement of a region of the degraded frame and the loss of image data. As of yet no method of ... -
Bandwidth-adaptive waveforms for dynamic spectrum access networks
(IEEE, 2008)This paper presents a novel solution to the challenge of waveform bandwidth estimation in DySPAN systems using intentionally embedded cyclostationary signatures. Dynamic spectrum access networks (DySPANs) achieve high ... -
A Bayesian Framework for Recursive Object Removal in Movie Post-Production
(IEEE, 2003)Some of the most convincing film and video effects are created in digital post-production by removing apparatus that supports or manipulates actors and objects. Wires and people, for instance, can be removed by digitally ... -
Classification and representation of semantic content in broadcast tennis videos
(IEEE, 2005)This paper investigates the semantic analysis of broadcast tennis footage. We consider the spatio-temporal behaviour of an object in the footage as being the embodiment of a semantic event. This object is tracked using ... -
Combinatorial clock auction for OFDMA-based cognitive wireless networks
(IEEE, 2008)This paper presents a novel application of a market-based spectrum assignment mechanism for exploitation by cognitive radio systems. Advances in DSA policy mean that regulators are moving towards a more liberalised ... -
A Comparative Error Analysis of Audio-Visual Source Localization
(2008)This paper examines the accuracy of audio-video based localization using multiple cameras and multi-microphones. Covariance mapping theory is used to determine the accuracy of audio and video based localization. Both ... -
Cyclostationary signatures for rendezvous in OFDM-based dynamic spectrum access networks
(IEEE, 2007)Abstract?Distributed coordination of operating frequencies and bandwidths is one of the key challenges in the development of dynamic spectrum access (DSA) technology. The spectrum efficiency of DSA networks is achieved ... -
Cyclostationary signatures in practical cognitive radio applications
(IEEE, 2008)We define a cyclostationary signature as a feature which may be intentionally embedded in a digital communications signal, detected through cyclostationary analysis and used as a unique identifier. The purpose of this paper ... -
Demonstration and analyses of collaboration, co-existence, and interoperability of cognitive radio platforms
(IEEE, 2007)The Centre for Telecommunications Value-Chain Research (CTVR) and the Center for Wireless Telecommunications (CWT) are undertaking a joint collaborative research project investigating the potential of different ... -
Detection of Illegal Dumping from CCTV at Recycling Centres
(2007)This paper describes initial work on a framework for automatic detection of illegal dumping from CCTV footage from recycle centres. Frames are seperated into foreground and background regions using a Bayesian approach that ... -
Dynamic spectrum access and coexistence experiences involving two independently developed cognitive radio testbeds
(IEEE, 2007)The Centre for Telecommunications Value-Chain Research (CTVR) and the Center for Wireless Telecommunications (CWT) are carrying out joint research work investigating the potential of different software-defined radio ... -
Dynamic Time Warping for Acoustic Response Interpolation: Possibilities and Limitations
(2009)We present a novel method for the interpolation of the direct and early reflection components in acoustic impulse responses. The method utilizes Dynamic Time Warping for automated temporal alignment of the sparse reflections. ... -
Effect of ZnS Shell Thickness on the Phonon Spectra in CdSe Quantum Dots
(The American Physical Society, 2003)The evolution of the optical phonon spectra of colloidal core/shell CdSe/ZnS quantum dots with an increase of the shell thickness from 0.5 to 3.4 monolayers has been studied by resonant Raman spectroscopy. The results ... -
Electrocardiogram based neonatal seizure detection
(IEEE, 2007)A method for the detection of seizures in the newborn using the electrocardiogram (ECG) signal is presented. Using a database of eight recordings, a method was developed for automatically annotating each 1-min epoch as ... -
Electronic slide matching and enhancement of a lecture video
(2007)This paper presents an automatic method to enhance video presentations for distance learning applications. From a material recorded by a fixed, non professional camera, the system matches the slides displayed during the ... -
Enabling dynamic spectrum access using SS-MC-CDMA
(IEEE, 2007)The demand for frequency spectrum and diversity of wireless devices accessing this spectrum depends upon the time of day, the characteristics of a frequency band, and the geographical location of the observer/wireless ... -
An encapsulation for reasoning, learning, knowledge representation, and reconfiguration cognitive radio elements
(IEEE, 2007)State and contextual awareness, reasoning and conclusions formation, and a means of directing application, structural and parameter-level radio reconfiguration are key elements of a cognitive radio. This paper describes a ...
