User-Assisted Feature Correspondence Matching.
(IEEE, 2009)Feature matching is a vital stage in many image processing applications. Finding accurate correspondences is made difficult by phenomena such as occlusions, non-rigid deformations, motion blur and more. We posit that some ... -
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, ... -
Using broad phonetic group experts for improved speech recognition
(IEEE, 2007)In phoneme recognition experiments, it was found that approximately 75% of misclassified frames were assigned labels within the same broad phonetic group (BPG). While the phoneme can be described as the smallest ... -
Using Conceptual Metaphors to Represent Temporal Context in Time-Series Data Sonification
(2020)This article explores how conceptual metaphor theory can be applied to the problem of representing temporal context in the sonification of time series data. It opens with an introduction to some of the conceptual metaphors ... -
Using One Graph-Cut to Fuse Multiple Candidate Maps in Depth Estimation.
(2009)Graph-cut techniques for depth and disparity estimations are known to be powerful but also slow. We propose a graph-cut framework that is able to estimate depth maps from a set of candidate values. By employing a ... -
V-shaped electro-optic response observed in a chiral ferroelectric smectic liquid crystal
(2008)We report on the observation of V-shaped switching in a ferroelectric liquid crystal cell over a wide range of temperatures. Results of the optical transmittance in the visible region give us the helical pitch for various ... -
Variation of features of interframe dependent HMM for speech recognition
(1998)The effects are explored of using different dynamic features in conjunction with an HMM that permits a dependency on both preceeding and succeeding frames. In particular, features which capture dynamic information are ... -
A Variational Bayes Approach to Decoding in a Phase-Uncertain Digital Receiver
(2011)This paper presents a Bayesian approach to symbol and phase inference in a phase-unsynchronized digital receiver. It primarily extends [Quinn 2011] to the multi-symbol case, using the variational Bayes (VB) approximation ... -
Various liquid crystalline phases structural analysis using resonant x-ray scattering
(2022)Chiral smectic liquid crystals have a paraelectric phase, a ferroelectric phase, and an antiferroelectric phase. Therefore, multiple phases called secondary phases appear, and sequential phase transitions are observed. ... -
VEGa: A high performance vehicular Ethernet gateway on hybrid FPGA
(2017)Modern vehicles employ a large amount of distributed computation and require the underlying communication scheme to provide high bandwidth and low latency. Existing communication protocols like Controller Area Network (CAN) ... -
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 ...
