Filter Learning for Linear Structure Segmentation

Pascal Fua, Engin Türetken, Vincent Lepetit, Germán González Serrano, Roberto Rigamonti

We introduce an approach to learning convolution filters whose joint output can be fed to a classifier that labels them as belonging to linear structures or not. The filters are learned using sparse synthesis techniques but we show that enforcing constrain ...

Estimating multiple filters from stereo mixtures: a double sparsity approach

Rémi Gribonval

We consider the problem of estimating multiple filters from convolutive mixtures of several unknown sources. We propose to exploit both the time-frequency (TF) sparsity of the sources and the sparsity of the mixing filters. Our framework consists of: a) a ...

Low-Power and Widely-Tunable Linearized Biquadratic Low-Pass Transconductor-C Filter

Seyed Armin Tajalli, Yusuf Leblebici

A sixth-order low-pass

g_m

-C filter with a very wide tuning range (

f_c

= 100 Hz to 10 MHz) is presented. The wide tuning range has been achieved without using switchable components or programmable building blocks. A single stage folded-cascode transcon ...

A Wideband Doubly-Sparse Approach For MITO Sparse Filter Estimation

Rémi Gribonval

We propose an approach for the estimation of sparse filters from a convolutive mixture of sources, exploiting the time-domain sparsity of the mixing filters and the sparsity of the sources in the time-frequency (TF) domain. The proposed approach is based o ...

Coupling matrix synthesis of dissipative microwave filters

Michael Mattes, Francisco Edén Sorolla Rosario, Diego Navarro Tapia

This study reviews the coupling matrix synthesis of dissipative microwave filters. It compares it to the synthesis of lossless transfer functions and shows that by correctly interpreting the mathematical operations in the lossless case, that is especially ...

Transient Analysis of Adaptive Affine Combinations

Ali H. Sayed

In this correspondence, we provide a transient analysis of an affinely constrained mixture method that adaptively combines the outputs of adaptive filters running in parallel on the same task. The affinely constrained mixture is adapted using a stochastic ...

Spatio-Chromatic Decorrelation by Shift-Invariant Filtering

Pascal Fua, Sabine Süsstrunk, Matthew Brown

In this paper we derive convolutional filters for colour image whitening and decorrelation. Whilst whitening can be achieved via eigendecomposition of the image patch covariance, this operation is neither efficient nor biologically plausible. Given the shi ...

Harmonic frequency tracking algorithm for predicting the success of pharmacological cardioversion of atrial fibrillation

Jean-Marc Vesin, Laurent Renaud Uldry, Andréa Buttu, Jérôme Sébastien Van Zaen, Lukas Kappenberger

Purpose: Non-invasively predicting the success of pharmacological cardioversion for patients with atrial fibrillation (AF) would be of great interest in clinical settings. In this study, an adaptive algorithm for tracking fundamental and harmonic component ...

Development of hybrid organic-inorganic materials for efficient charging/discharging in electrochemical and photoelectrochemical capacitors

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt

A composite system of poly (3,4-ethylenedioxythiophene)/multi-walled carbon nanotubes has been investigated and characterized as a potential charge storage material for coupled dye-sensitized solar cell/electrochem. capacitor systems. The selected material ...

Direct-Ambient Decomposition and Upmix of Surround Signals

Christof Faller, Andreas Walther

Various direct-ambient signal decompositions, applicable to two-channel stereophonic signals, have been proposed previously. Strategies to enhance these decompositions for multi-channel surround audio signals are not obvious. A method is proposed, which es ...
