Consistent and Regularized Magnification of Images

Michaël Unser, Philippe Thévenaz, Aurélien Bourquard, Katarina Balac

Because more output data must be created than is available from the input, magnification is an ill-posed problem. Traditional magnification relies on resampling an interpolation model at the appropriate rate; unfortunately, this simple solution is blind to ...

A low-power 2.4 GHz CMOS receiver using BAW resonators

Jérémie Chabloz

It has already been a few years since the first appearance of micro-electromechanical systems (MEMS) in academic research. Since then, a broad number of devices have been designed under this generic term. Bulk-acoustic wave (BAW) resonators are among the f ...

Introducing Temporal Asymmetries in Feature Extraction for Automatic Speech Recognition

Hynek Hermansky

We propose a new auditory inspired feature extraction technique for automatic speech recognition (ASR). Features are extracted by filtering the temporal trajectory of spectral energies in each critical band of speech by a bank of finite impulse response (F ...

Power and Area Efficient Circular-Memory Switched-Capacitor FIR Baseband Filter for WCDMA/GSM

Rafal Tomasz Dlugosz

This paper presents a new two-sections architecture of a low power switched capacitor (SC) finite impulse response (FIR) filter suitable for base-band signal processing in WCDMA and in GSM standards. The low power operation is possible due to several optim ...

Shape from Texture for Omnidirectional Images

Pierre Vandergheynst, Luigi Bagnato, Laurent Jacques, Eugenio De Vito

In this paper, we describe a method to infer 3-D scene information using a single view captured by an omnidirectional camera. The proposed technique is inscribed in the so called ``Shape from Texture'' problem : if the textures hold by 3-D surfaces respect ...

UWB and MEMS Based Indoor Navigation

Bertrand Merminod, Sylvain Pittet

Thanks to its physical characteristics, Ultra-wideband (UWB) is one of the most promising technologies for indoor pedestrian navigation. UWB radio localisation systems however experience multipath phenomena that decrease the precision and the reliability o ...

Optimal Polynomial Filtering for Accelerating Distributed Consensus

Pascal Frossard, Effrosyni Kokiopoulou

In the past few years, the problem of distributed consensus has received a lot of attention, particularly in the framework of ad hoc sensor networks. Most methods proposed in the literature attack this problem by distributed linear iterative algorithms, wi ...

A Subthreshold SCL Based Pipelined Encoder for Ultra-Low Power 8-bit Folding/Interpolating ADC

Seyed Armin Tajalli, Yusuf Leblebici, Mohammad Beikahmadi

The subthreshold MOS source-coupled logic (STSCL) technique is of great interest for designing ultra low power circuits. In this paper we discuss the design of a pipelined encoder for an 8-bit folding and interpolating (F&I) analog-to-digital (ADC) data co ...

The Pairing of a Wavelet Basis With a Mildly Redundant Analysis via Subband Regression

Michaël Unser, Dimitri Nestor Alice Van De Ville

A distinction is usually made between wavelet bases and wavelet frames. The former are associated with a one-to-one representation of signals, which is somewhat constrained but most efficient computationally. The latter are over-complete, but they offer ad ...
