Dept Images Signal
11 Rue des mathematiques
38402 St Martin d'Heres, FRANCE


Welcome ! I am currently Chargé de Recherche with the CNRS at Gipsa-Lab. From 2013 to 2015, I was a visiting research fellow at the Department of Electronic and Electrical Engineering, The University of Melbourne, Australia. My research in Melbourne and Grenoble was supported by a Marie Curie International Outgoing Fellowship (IOF) from the European Union and the CNRS.

LIA GEODESIC: New Website.

The LIA GEODESIC is an International Associated Lab co-funded by the CNRS, France, and the University of Melbourne, Australia. Visit our website for annoucements, internship positions and opportunities related to Geometry Driven Signal and Image Processing Lab. Website

Post-Doc position: one year post-doc position available.

A one year post-doc position is available to work in collaboration with Christophe Prieur on "Estimating the Earth’s magnetic heading in a moving vehicle" at gipsa-lab, Grenoble, France. Contact us if interested in applying for this position.

BiSPy: a python framework for bivariate signal processing, available here with documentation.

Bispy is a Python toolbox for bivariate signal processing. It comes along with our submitted paper "Time-frequency analysis of bivariate signals", by J. Flamant, N. Le Bihan and P. Chainais (ArXiV version).

Hypercomplex Signal Processing: a special issue of Elsevier Signal Processing magazine (link).

With my colleagues Todd A. Ell, Danilo Mandic, Tohru Nitta and Stephen J. Sangwine, we have co-edited a special issue of the Elsevier Signal Processing journal dedicated to hypercomplex signal processing latest advances.

Quaternion Fourier transforms for signal and image processing, (ISTE-Wiley, May 2014, ISBN 978-1-84821-478-1)


Based on updates to signal and image processing technology made in the last two decades, this text examines the most recent research results pertaining to Quaternion Fourier Transforms (QFT). QFT is a central component of processing color images and complex valued signals. The book’s attention to mathematical concepts, imaging applications, and Matlab compatibility render it an irreplaceable resource for students, scientists, researchers, and engineers.

QTFM - A Quaternion Toolbox for Matlab

In collaboration with Stephen J. Sangwine (Univ. of Essex, UK), we have developped a Toolbox that enables Matlab to handle quaternions just like it does handle real and complex numbers. The Toolbox contains basic operations for quaternions as well as some more advanced algorithm like Quaternion FFT and SVD for matrices with quaternion coefficients. The toolbox allows also to manipulate complexified quaternions (biquaternions). QFTM is freely available from sourceforge using this link. (Last Version 2.1, May 2014)
