Subpixel translation of MEMS measured by discrete Fourier transform analysis of CCD images

Martinus Gijs, Christophe Yamahata, Marc Stranczl

We present a straightforward method for measuring in-plane linear displacements of microelectromechanical systems (MEMS) with a subnanometer resolution. The technique is based on Fourier transform analysis of a video recorded with a Charge-Coupled Device ( ...

Privacy-Sensitive Audio Features for Speech/Nonspeech Detection

Hervé Bourlard, Daniel Gatica-Perez, Sree Hari Krishnan Parthasarathi

The goal of this paper is to investigate features for speech/nonspeech detection (SND) having ``minimal'' linguistic information from the speech signal. Towards this, we present a comprehensive study of privacy-sensitive features for SND in multiparty conv ...

Rate-Distortion Curve Evaluation for Cross-Layer Optimization in Progressive Video Transmission

Laura Toni

Robust streaming of video over wireless networks poses many challenges, as coping with bandwidth variations, data losses, and heterogeneity of the receivers. Rate-distortion (RD) optimization studies are aimed at increasing the reliability of received bits ...

Source/Filter Model for Unsupervised Main Melody Extraction From Polyphonic Audio Signals

Extracting the main melody from a polyphonic music recording seems natural even to untrained human listeners. To a certain extent it is related to the concept of source separation, with the human ability of focusing on a specific source in order to extract ...

Preferential Orientation in Hematite Films for Solar Hydrogen Production via Water Splitting

Michael Graetzel, Kevin Sivula, Maurin Cornuz

The state-of-the-art performance, obtained through the reduction of precursor gas residence time in hematite photoanodes produced by APCVD, is explained in this report by an enhanced preferential orientation of the highly conductive crystal planes perpendi ...

Improved Side Information Generation for Distributed Video Coding by Exploiting Spatial and Temporal Correlations

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm in video coding, which is receiving a lot of interests nowadays. Side Information (SI) generation is a key function in the DVC decoder, and plays a key-role in determining the performance of the codec. This ...

Video monitoring of neovessel occlusion induced by photodynamic therapy with verteporfin (Visudyne(r)), in the CAM model

Hubert van den Bergh, Georges Wagnières, Elodie Debefve

The aim of the present study was to monitor photodynamic angioocclusion with verteporfin in capillaries. Details of this process were recorded under a microscope in real-time using a high-sensitivity video camera. A procedure was developed based on intrave ...

Joint acoustic-video fingerprinting of vehicles, part II

Volkan Cevher

In this second paper, we first show how to estimate the wheelbase length of a vehicle using line metrology in video. We then address the vehicle fingerprinting problem using vehicle silhouettes and color invariants. We combine the acoustic metrology and cl ...
