Vehicular Networks: Embracing Wireless Heterogeneous Communications through Vertical Handover
(2013)By taking advantage of the ever growing deployment of wireless networks, the automotive industry is increasingly enabling vehicles to communicate with one another and with the infrastructure, with benefits to information ... -
Video Matting Using Motion Extended GrabCut.
(IEEE, 2008)GrabCut is perhaps the most powerful semi-automatic algorithm for matting presented to date. In its existing form, it is not suitable for video object segmentation. This paper considers major extensions that make it ... -
ViSQOL: an objective speech quality model
(2015)This paper presents an objective speech quality model, ViSQOL, the Virtual Speech Quality Objective Listener. It is a signal-based, full-reference, intrusive metric that models human speech quality perception using a ... -
ViSQOL: The Virtual Speech Quality Objective Listener
(2012)A model of human speech quality perception has been developed to provide an objective measure for predicting subjective quality assessments. The Virtual Speech Quality Objective Listener (ViSQOL) model is a signal based ... -
ViSQOLAudio: An objective audio quality metric for low bitrate codecs
(2015)Streaming services seek to optimise their use of bandwidthacross audio and visual channels to maximise the quality of experiencefor users. This letter evaluates whether objective quality metrics can pre-dict the audio ... -
A Viterbi tracker for local features
(SPIE, 2010)The long term tracking of sparse local features in an image is important for many applications including camera calibration for stereo applications, camera or global motion estimation and people surveillance. The majority ... -
Vowel Formant Profiles and Image Schemata and Auditory Display
(2018)This paper presents two evaluations intended to examine if listeners are more likely to associate certain vowel formant profiles with specific data types in an auditory display context. The data types and sounds chosen ... -
Watermarking digital images for copyright protection
(IEE, 1996)A watermark is an invisible mark placed on an image that is designed to identify both the source of an image as well as its intended recipient. The authors present an overview of watermarking techniques and demonstrate a ... -
Watermarking digital images for copyright protection
(IEE, 1995)A watermark is all invisible mark placed on an image that can only be detected when the image is compared with the original. This mark is designed to identify both the source of a document as well as its intended recipient. ... -
A wavelet-based Bayesian framework for 3D object segmentation in microscopy
(2012)In confocal microscopy, target objects are labeled with fluorescent markers in the living specimen, and usually appear with irregular brightness in the observed images. Also, due to the existence of out-of-focus objects ... -
Whispering gallery mode emission from photonic microtubes
(IEEE, 2006)We have found cylindrical glass microtubes can be formed by vacuum assisted filtration using a micro-channel glass matrix followed by thermal treatment of the material. The microtubes are strongly luminescent and exhibit ... -
Whispering-gallery modes in photonic tubes
(Society of Photo-optical Instrumentation Engineers (SPIE), 2007)A new method has been developed to fabricate microtube resonators with strong whispering-gallery-mode emission and quality factors up to 3000. -
Whitespace Networks Relying on Dynamic Control Channels
(2013)The emergence of whitespace networks, and whitespace communications in general, provides an opportunity to, at least partially, meet the ever-growing demand for mobile data communication. Most of the whitespace network ... -
Whole-Body Magnetic Resonance Imaging Enables Assessing Spatial Accuracy and Precision of Skeletal Joint Locations Inferred from Motion Capture Systems
(2015)Motion capture systems can be used to infer skeletal joints from three-dimensional surface information for various human poses. However, to-date it remains unclear how well the estimated joint coordinates coincide with ... -
Whole-body sodium-mri at 3 T using an asymmetric birdcage resonator and short echo time sequence: first images of a male volunteer
(2012)Sodium magnetic resonance imaging (²³Na MRI) is a non-invasive technique which allows spatial resolution of the tissue sodium concentration (TSC) in the human body. TSC measurements could potentially serve to monitor early ... -

X-ray diffraction study of ferroelectric and antiferroelectric liquid crystal mixtures exhibiting de Vries SmA∗-SmC∗ transitions
(2010)In this Rapid Communication, results on smectic layer thickness, using synchrotron radiation x-ray diffraction, for different mixtures of ferroelectric and antiferroelectric liquid crystals are given. We find that with ...
