Welcome to my home page.
I completed my PhD in Mathematical Morphology (Center of Mathematical Morphology, Paris School of Mines) under the supervision of Michel Bilodeau.
I then joined DxO Labs, a start-up company specialized in digital image quality enhancement. I was involved in the "Image Quality Evaluation" business line.
I am currently a research fellow (postdoc) at INRIA Paris-Rocquencourt, IMEDIA research team. My topics are: multimedia databases,
scalable summarization techniques, feature extraction and machine learning.
My research interests include color processing, segmentation, distance transforms, tracking, robust features extraction, dimension reduction, distributed computing, mathematical morphology.
Check out my new project: YAYI ! An highly generic and powerful platform for image processing (started from scratch).

Multidimensional and multispectral algorithms in the field of Mathematical Morphology :
The meta-programming approach. The PhD focuses on the use of the meta-programming approach (namely C++) for developing Mathematical Morphology and Image Processing tools. Several algorithms using the proposed multidimensional and multispectral framework are presented (watershed in any dimension, viscous watershed, contrained flooding, exact discrete convex distances transforms, algebraic and statistical colour approach, etc.). Detailed summary (also here). Complete manuscript (on Pastel servers, in French, PDF, 52 MB) |

Algorithmes multidimensionnels et multispectraux en Morphologie Mathématique : approche par méta-programmation. Le sujet de ma thèse concerne l'approche par méta-programmation (C++) pour le développement d'une bibliothèque complète de Morphologie Mathématique et de Traitement d'Images. De nombreux algorithmes (distance, segmentation, couleur) sont également développés dans ce cadre. Résumé complet (également sur PASTEL). Manuscrit complet (serveurs Pastel, français, PDF, 52 MB) |
