Advanced video debanding
(ACM, 2014)High efficiency video coding has made it possible to stream video over bandwidth constrained communication networks. Depending on bit rate requirements, a video encoder sacrifices some image de- tails which can then ... -
User-assisted reflection detection and feature point tracking
(2013)Reflections in image sequences violate the single layer model used by most current image processing techniques. As a result reflec- tions cause many techniques to fail e.g. detection, tracking, motion estimation, etc. ... -
User-assisted sparse stereo-video segmentation
(2013)User-assisted Sparse Stereo-video Segmentation Félix Raimbault, François Pitié and Anil Kokaram Sigmedia Group Dept. of Electronic and Electrical Engineering Trinity College Dublin, Ireland {raimbauf, fpitie, ... -
Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique
(2013)This paper has two main contributions. The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches. Most removal techniques assume complete obliteration of ... -
The cruciform model of striate generation of the early VEP, re-illustrated, not revoked: A reply to Ales et al. (2013)
(2013)Here we summarize the points raised in our dialog with Ales and colleagues on the cortical generators of the early visual evoked potential (VEP), and offer observations on the results of additional simulations that were ... -
Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique
(Springer, 2013)This paper has two main contributions. The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches. Most removal techniques assume complete obliteration of ... -
Polarization anisotropy of photoluminescence from triphenylamine-based molecular single crystal
(2013)We present an experimental study of the polarization of the photoluminescence (PL) emission from a (Z)-3-(4-(diphenyl- amino)phenyl)-2-(pyridin-2-yl)-acrylonitrile (DPPyACN) single organic crystal. Our measurements show ... -
Influence of the buffer layer properties on the intensity of Raman scattering of graphene
(2013)Using a model of oscillating dipoles, we simulate the intensity of the G-band in the Raman signal from structures consisting of graphene, separated by an arbitrary buffer layer from a substrate. It is found that a structure ... -

Spin-torque effects in thermally assisted magnetisation reversal: Method of statistical moments
(2013)Thermal fluctuations of nanomagnets driven by spin-polarized currents are treated via the Landau-Lifshitz-Gilbert equation generalized to include both the random thermal noise field and the Slonczewski spin-transfer torque ... -
Robustness and prediction accuracy of machine learning for objective visual quality assessment
(2014)Machine Learning (ML) is a powerful tool to support the development of objective visual quality assessment metrics, serving as a substitute model for the perceptual mechanisms acting in visual quality appreciation. ... -
Testbed Federation: An Approach for Experimentation-driven Research in Cognitive Radios and Cognitive Networking
(2011)The sub-optimal exploitation of radio spectrum is widely accepted. Cognitive radio is a technol ogy that aims to address this issue and improve the overall efficiency of radio spectrum utiliza tion. However, this ... -
Carrier Aggregation as a Repeated Game: Learning Algorithms for Efficient Convergence to a Nash Equilibrium
(2013)Carrier aggregation is a key feature of next generation wireless networks to deliver high-bandwidth links. This paper studies carrier aggregation for au- tonomous networks operating in shared spectrum. In our model, ... -
Adaptation in a Channel Access Game with Private Monitoring
(2013)Under the opportunistic spectrum access paradigm, the shared pool of spectrum bands that the multiple autonomous cognitive radios (CRs) need to compete for is not necessarily homogeneous. The non-homogeneity in channels ... -
The effect of the spectrum opportunities diversity on opportunistic access
(IEEE, 2013)To improve their ability to find spectrum oppor- tunities, intelligent secondary radios (SR) can learn from their past observations and predict possible spectrum opportunities. However, because of the diverse behavior ... -
Radar, TV, and Cellular Bands: Which Spectrum Access Technique for Which Bands?
(2014)Opportunistic access has been considered by regu- lators for a number of different spectrum bands. In this paper, we discuss and qualitatively evaluate techniques used in the discovery of spectrum opportunities, also ...
