Second-order linear hyperbolic SPDEs driven by isotropic Gaussian noise on a sphere

Robert Dalang, Olivier Lévêque

We study a class of linear hyperbolic stochastic partial differential equations in bounded domains, that includes the wave equation and the telegraph equation, driven by Gaussian noise that is white in time but not in space. We give necessary and sufficien ...

Visibility of noise in natural images

Sabine Süsstrunk, Stefan Winkler

The degree of visibility of any kind of stimulus is largely determined by the background on which it is shown, a property commonly known as masking. Many psychophysical experiments have been carried out to date to understand masking of sinusoids or Gabor t ...

Robust Features for Frontal Face Authentication in Difficult Image Conditions

Samy Bengio

In this report we extend the recently proposed {DCT}-mod2 feature extraction technique (which utilizes polynomial coefficients derived from {2D} {DCT} coefficients obtained from horizontally & vertically neighbouring blocks) via the use of various windows ...

Resonator stability subject to dynamic random-tilt aberration

Theo Lasser, Max-Olivier Hongler

We derive the behavior of the average exit time (i.e., the number of reflections before escape) of a ray path traveling between two perfect mirrors subject to dynamic random-tilt aberrations. Our calculation is performed in the paraxial approximation. When ...

Source separation in strong noisy mixtures: A study of wavelet de-noising pre-processing

Kamiar Aminian, Philippe Robert, Anisoara Ionescu, Bijan Najafi

This paper addresses the source separation in strong noisy mixtures by wavelet de-noising processing. Experiments include the cases of white/correlated Gaussian and non- Gaussian noise, which correspond to various applications. The performance of BSS/ICA a ...

Calcul stochastique appliqué aux problèmes de détection des signaux aléatoires

Signal detection is one of the basic problems in statistical communication theory, and has many applications to contemporary technology, whether in engineering, medical science, or the environment. The most difficult problems are those involving random sig ...

Resolution of fluorescence correlation measurements

Horst Vogel

The resoln. limit of fluorescence correlation spectroscopy for two-component solns. is investigated theor. and exptl. The autocorrelation function for two different particles in soln. were computed, statistical noise was added, and the resulting curve was ...

Adaptive tracking of linear time-variant systems by extended RLS algorithms

Ali H. Sayed

We exploit the one-to-one correspondences between the recursive least-squares (RLS) and Kalman variables to formulate extended forms of the RLS algorithm. Two particular forms of the extended RLS algorithm are considered: one pertaining to a system identif ...
