Automatic Feature Learning for Spatio-Spectral Image Classification With Sparse SVM

Including spatial information is a key step for successful remote sensing image classification. In particular, when dealing with high spatial resolution, if local variability is strongly reduced by spatial filtering, the classification performance results ...

Simple merging technique for improving resolution in qualitative single image phase contrast tomography

Peter Modregger, Zheng Wang, Marco Stampanoni

For dynamic samples and/or for simple ease-of-use experiments, single-image phase contrast tomography is a very effective method for the 3D visualization of materials which would otherwise be indiscernible in attenuation based x-ray imaging. With binary sa ...

Sampling and Reconstruction of Spatial Fields using Mobile Sensors

Martin Vetterli, Jayakrishnan Unnikrishnan

Spatial sampling is traditionally studied in a static setting where static sensors scattered around space take measurements of the spatial field at their locations. In this paper we study the emerging paradigm of sampling and reconstructing spatial fields ...

Demodulation of Spatial Carrier Images: Performance Analysis of Several Algorithms Using a Single Image

Sébastien Equis

Optical full-field techniques have a great importance in modern experimental mechanics. Even if they are reasonably spread among the university laboratories, their diffusion in industrial companies remains very narrow for several reasons, especially a lack ...

The impact of denoising on independent component analysis of functional magnetic resonance imaging data

Dimitri Nestor Alice Van De Ville, Thierry Pun, Christoph Michel

Independent component analysis (ICA) is a suitable method for decomposing functional magnetic resonance imaging (fMRI) activity into spatially independent patterns. Practice has revealed that low-pass filtering prior to ICA may improve ICA results by reduc ...

Analysis of Descent-Based Image Registration

Pascal Frossard, Elif Vural

We present a performance analysis for image registration with gradient descent. We consider a typical multiscale registration setting where the global 2-D translation between a pair of images is estimated by smoothing the images and minimizing the distance ...

Single trial analysis of slow cortical potentials: A study on anticipation related potentials

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Gangadhar Garipelli

Objective. Abundant literature suggests the use of Slow Cortical Potentials (SCPs) in a wide spectrum of basic and applied neuroscience areas. Due to low signal to noise ratio, often these potentials are studied using grand-average analysis, which conceal ...

Large eddy simulation of the differentially heated cubic cavity flow by the spectral element method

Michel Deville, Emmanuel Leriche, Christoph Bosshard, Alfredo Soldati, Riccardo Puragliesi, Abdelouahab Dehbi

Large eddy simulations of the turbulent natural convection flow in a differentially heated cavity have been carried out at a Rayleigh number of 10(9) using the spectral element method. To obtain the large eddy simulation equations, a low pass filter given ...

Spatial filters for bridging molecular dynamics with finite elements at finite temperatures

Jean-François Molinari, Guillaume Anciaux, Srinivasa Babu Ramisetti

We present the application of digital filters to split the energy spectrum of an atomistic zone simulated with molecular dynamics into low and high energy components. After a brief background on digital filters, we describe the procedure used to select a c ...
