Robust Array Calibration Using Time Delays with Application to Ultrasound Tomography

Martin Vetterli, Olivier Roy, Ivana Jovanovic

Accurate calibration is a requirement of many array signal processing techniques. We investigate the calibration of a transducer array using time delays. We derive a strategy based on the mean square error criterion and discuss how time delays that are not ...

Dynamic hair capture

Mark Pauly, Hao Li

The realistic reconstruction of hair motion is challenging because of hair’s complex occlusion, lack of a well-defined surface, and non-Lambertian material. We present a system for passive capture of dynamic hair performances using a set of high-speed vide ...

Drift Correction in Multivariate Calibration Models Using On-line Reference Measurements

Dominique Bonvin, Michael Amrhein, Pamandeep Singh Gujral

On-line measurements from first-order instruments such as spectrometers may be compromised by instrumental, process and operational drifts that are not seen during off-line calibration. This can render the calibration model unsuitable for prediction of key ...

SURE-Based Non-Local Means

Dimitri Nestor Alice Van De Ville, Michel Kocher

Non-local means (NLM) provides a powerful framework for denoising. However, there are a few parameters of the algorithm-most notably, the width of the smoothing kernel-that are data-dependent and difficult to tune. Here, we propose to use Stein's unbiased ...

Two-level bimodal association for audio-visual speech recognition

Touradj Ebrahimi, Jong Seok Lee

This paper proposes a new method for bimodal information fusion in audio-visual speech recognition, where cross-modal association is considered in two levels. First, the acoustic and the visual data streams are combined at the feature level by using the ca ...

Dynamic modality weighting for multi-stream HMMs in Audio- Visual Speech Recognition

Jean-Philippe Thiran, Mihai Gurban, Thomas Drugman

Merging decisions from different modalities is a crucial problem in Audio-Visual Speech Recognition. To solve this, state synchronous multi-stream HMMs have been proposed for their important advantage of incorporating stream reliability in their fusion sch ...

Far-field Continuous Speech Recognition System based on Speaker Localization and Sub-band Beamformin

Afsaneh Asaei, Mohammadjavad Taghizadeh

This paper proposes a Distant Speech Recognition system based on a novel speaker Localization and Beamforming (SRLB) algorithm. To localize the speaker an algorithm based on Steered Response Power by utilizing harmonic structures of speech signal is propos ...

Blind optimization of algorithm parameters for signal denoising by Monte-Carlo sure

Michaël Unser, Thierry Blu, Sathish Ramani

We consider the problem of optimizing the parameters of an arbitrary denoising algorithm by minimizing Stein's Unbiased Risk Estimate (SURE) which provides a means of assessing the true mean-squared-error (MSE) purely from the measured data assuming that i ...
