A fun project is the Mathematics Genealogy Project. According to them, some of my ancestors are quite famous. They are, in chronological order, Jean-Pierre Aubin, Jacques-Louis Lions, Laurent Schwartz, Georges Valiron, Emile Borel, Gaston Darboux, Michel Chasles, Simeon Denis Poisson, Joseph Lagrange, Leonhard Euler, Johann Bernouilli, Jacob Bernouilli, Gottfried Leibniz and Erhard Weigel.

Featured paper: ultrametric watersheds

My pJMIVaper on ultrametric watersheds is amongst the selected  5 top-cited articles from the Journal of Mathematical Imaging and Vision available free until the end of September.

The paper is avalable here. This HAL version will be forever freely available.

Preprint on TV filtering

Our paper on Dual-Constrained Total Variation on Graphs has been accepted to SIAM Journal on Imaging Siences. Preprint is available, as well as source code.

Discrete curvature - November 18-22, 2013.


With Pascal Romon , we are organizing a colloquium on Discrete Curvature. The aim of this meeting is to bring together researchers from diverse backgrounds (including mathematics and computer science) on the common theme of discrete curvature and to make an update on the many achievements of the last decade. We want to promote interaction between various fields, so topics and participants can and should be varied, as long as they fit under the under the main theme. Prestigious speakers are already programmed.

The meeting will take place at the CIRM, in Luminy, near Marseille (France), from November 18th to the 22nd, 2013.

2nd place in a MICCAI challenge


The challenge was held on October 1st, 2012 in Nice Sophia Antipolis, Côte d'Azur, France, at the workshop 3D Cardiovascular Imaging: a MICCAI segmentation challenge at the 15th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI),

Preprint on scene parsing

The preprint of our upcoming IEEE Trans. PAMI on scene labeling is available. We use a multi-scale convolutional network trained in supervised mode on fully-labeled images in which each pixel is labeled by the category of the object it belongs to. A simple superpixel-based post-processing smoothes out the output labels and lines up the segment boundaries with image contours.
