Resume

I am a permanent CNRS research scientist (a.k.a. Chargé de Recherche), working in the IMAGE team at the GREYC Laboratory (UMR 6072), in Caen / France, since 2004.

Latest News

Software

I'm the manager and main developer of these open-source software/libraries, dedicated to image processing:

G'MIC (GREYC's Magic for Image Computing)

G'MIC (GREYC's Magic for Image Computing)

G'MIC is a full-featured open-source framework for digital image processing, distributed under the CeCILL free software licenses (LGPL-like and/or GPL-compatible). It provides several user interfaces to convert / process / visualize generic image datasets, ranging from 1D scalar signals to 3D+t sequences of multi-spectral volumetric images, hence including 2D color images.

CImg (C++ Template Image Processing Library)

The CImg Library (C++ Template Image Processing Library)

The CImg Library is a small and open-source C++ toolkit for image processing. It consists in a single header file providing a minimal set of C++ classes and methods that can be used in your own sources, to load/save, process and display images. Very portable (Unix/X11,Windows, MacOS X, FreeBSD, .. ), efficient, easy to use, it's a pleasant library for developing image processing algorithms in C++.

Image Processing Books

I'm the co-author of two books (one in English, one in French) with my colleagues Christophe Tilmant and Vincent Barra, that teach how to write image processing algorithms in C++ with the help of the CImg Library.

        
During 300+ pages, we review the important concepts of the CImg Library and address a wide variety of applications in image processing (Filtering, Mathematical Morphology, Feature Extraction, Segmentation, Multispectral Approaches, 3D Visualization, etc.).
If you don't know what to give your children for Christmas, this is a great gift idea! ☺
