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 ... -
Feature-Cut: Video Object Segmentation Through Local Feature Correspondences.
(IEEE Computer Society, 2009)Accurately segmenting objects in video is a difficult and time consuming process in modern post-production houses. Automatic systems may work for a small number of frames, but will typically fail over longer video shots. ... -
Information Retrieval Assisted Object Segmentation In Video.
(IEEE, 2008)Accurate object segmentation in video is difficult. The dynamic nature of the medium causes drifts in the feature spaces traditionally used in segmentation of objects in still images. For example, colour distributions, ... -
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 ... -
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 ... -
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 ... -
Feature-Assisted Sparse to Dense Motion Estimation using Geodesic Distances.
(IEEE, 2009)Large motion displacements in image sequences are still a problem for most motion estimation techniques. Progress in feature matching allows to establish robust correspondences between images for a sparse set of points. ... -
Measurement of phonemic degradation in sensorineural hearing loss using a computational model of the auditory periphery
(2009)A computational model of the auditory periphery enables faster investigation of new signal processing algorithms for hearing aids. This paper presents a study of the degradation of auditory nerve (AN) responses at a ... -
Error Metrics for Impaired Auditory Nerve Responses of Different Phoneme Groups
(2009)An auditory nerve model allows faster investigation of new signal processing algorithms for hearing aids. This paper presents a study of the degradation of auditory nerve (AN) responses at a phonetic level for a range ... -
Phase space Langevin equation for spin relaxation in a dc magnetic field
(IOP Publishing, 2009)A Langevin equation for the quantum Brownian motion of a spin of arbitrary size in a uniform external dc magnetic field is derived from the phase space master equation in the weak coupling and narrowing limits, for the ... -
Semiclassical treatment of a Brownian ratchet using the quantum Smoluchowski equation
(2009)Quantum effects in the noninertial Brownian motion of a particle in a one-dimensional ratchet potential are treated in the high temperature and weak bath-particle coupling limit by solving a quantum Smoluchowski equation ... -
Quantum effects in the Brownian motion of a particle in a double well potential in the overdamped limit.
(2009)Quantum effects in the noninertial Brownian motion of a particle in a double well potential are treated via a semiclassical Smoluchowski equation for the time evolution of the reduced Wigner distribution function in ... -
Localized relaxation in a glass and the minimum in its orientational polarization contribution
(American Institute of Physics, 2002)The dielectric permittivity and loss spectra of the glassy state of 5-methyl-2-hexanol obtained by quenching it from the liquid state has been studied. In one experiment, the spectra were studied at different temperatures ... -
Localized relaxation's strength and its mimicry of glass-softening thermodynamics.
(American Institute of Physics, 2002)The dielectric relaxation strength of the ? process, ???, in a rigid-molecular glass of 16.6 mol?% chlorobenzene cis-decalin mixture increases slowly with temperature, T, until the glass-softening range is reached, and ... -
The investigation of the relaxation processes in antiferroelectric liquid crystals by electro-optic spectroscopy
(American Institute of Physics, 1998)Electrooptic spectroscopy of an antiferroelectric liquid crystal is carried out over a range of frequencies from 1 Hz to 100 kHz. In the antiferroelectric SmCA phase two relaxation processes are found, one at the fundamental ... -
Measurement of the polarization profile across a surface-stabilized ferroelectric liquid crystal cell using the pyroelectric laser-intensity-modulation method
(American Institute of Physics, 2003)The pyroelectric technique, called the laser-intensity-modulation method, was used for investigations of the spatial distribution of the pyroelectric coefficient that gives information about the director profile in ... -
Comment on Submillimeter spectroscopic study of concentrated electrolyte solutions as high density plasma
(American Institute of Physics, 2003)The authors of the title article: (1) contrary to their findings did not fully comprehend that in our paper [Phys. Chem. Chem. Phys., 3, 523 (2001)], the estimated contribution of ions oscillating between the two "reflecting ... -
Comparison of the characteristics of the chiral analog of the de Vries type of smectic-A* phase
(The American Physical Society, 2003)In this paper we compare the results of three ferroelectric materials that exhibit unusual smectic-A (SmA) phases. These phases have been assigned to chiral analogs of the de Vries SmA phase. Several experimental techniques ...
