Work:

I am a researcher in applied mathematics at the CMLA in ENS Cachan and at the CEREMADE in Paris. My PhD thesis focused on a new contrast invariant representation of images, based on the inclusion structure of level lines, which led to several applications: study and implementation of the grain filter, a new adaptive quantization algorithm, and especially image registration. If interested, take a look at the abstract or at some slides.
My current research interests are focused on video analysis, with emphasis on motion in videos.
My master was about a totally different subject: the goal was to construct a new family of wavelet bases on an interval, verifying prescribed boundary conditions, in order to solve numerically Partial Differential Equations.

Some related links:

My research is in the field of mathematical morphology, originating from the Centre de Morphologie Mathématique
Simon Masnou, during his PhD thesis, introduced and studied the grain filter in the BV framework
My decomposition of the image into a tree of level lines has some links to Digital Morse Theory
Salembier worked on the design of morphological filters based on a tree representation of images
I use the Megawave image processing environment (my source code of the decomposition of an image into a tree of shapes, the FLST, is inside)
I advise you to take a look at the web pages of my colleagues working also on mathematical morphology: Frédéric Guichard, Lionel Moisan, Frédéric Cao, Yann Gousseau and François Malgouyres
I participate to the algorithmic part of the video software of Cognitech
