International audience; This paper presents an extension of the spatio-spectral (" 3D ") image reconstruction algorithm called PAINTER (Polychromatic opticAl INTErferometric Reconstruction software). The algorithm is able to solve large scale problem

International audience; We present a method to recontruct temperature map directly from spectro-interferometric data. It uses a sparse coding method to describe each pixel as a blackbody. Results are shown on the Herbig Be HD98922. Aside from recover

International audience; We have recently shown that a posteriori co-phasing of multi-spectral interferograms was possible. 1 In this contribution, we extend our approach so that it can be applied to actual data as provided by Amber 2 or Matisse instr

Statistical characterization of polychromatic absolute and differential squared visibilities obtained from AMBER/VLTI instrument

Autor: André Ferrari, David Mary, Florentin Millour, Antony Schutz, Martin Vannier, Romain Petrov

In optical interferometry, the visibility squared modulus are generally assumed to follow a Gaussian distribution and to be independent of each other. A quantitative analysis of the relevance of such assumptions is important to help improving the exp

Single-microphone blind audio source separation via Gaussian short+long term AR models

Autor: Antony Schutz, Dirk Slock

Publikováno v: 2010 4th International Symposium on Communications, Control and Signal Processing (ISCCSP).

Blind audio source separation (BASS) arises in a number of applications in speech and music processing such as speech enhancement, speaker diarization, automated music transcription etc. Generally, BASS methods consider multichannel signal capture. T
