Research Interests
My research interests lie in the image content modelling and synthesis of expressive images and medical images.
I am presently an associate professor (maître de conférences) in Paris Descartes University, member of the LIPADE lab, and an adjunct associate professor of Ecole Polytechnique de Montréal in the Computer Science department. From november 2008 until july 2009, I was a post-doc in the INRIA ARTIS group with Joëlle Thollot. I have obtained my Ph.D. at the Télécom Paris school and Ecole Polytechnique de Montréal under the guidance of the late Francis Schmitt, Yann Gousseau and Farida Cheriet. I received a FQRNT doctoral scholarship during 2006-2007.
I presently coordinate the research project SPIRIT, funded by the French National Research Agency (ANR).

)
Three examples of example-based synthesis. Top left, a user draws a texture arrangement of stroke-based elements. Top right, elements are categorized based on their visual appearance. Bottom, spatial relationships is learnt in the example using a statistical model, and the texture can next be automatically synthesized at larger sizes.

During my PhD thesis, I studied the pictorial effect of line-drawings. This effect can be understood as the preattentive visual impression before any semantic reconstruction, as also studied by Julesz. It is closely related to the artistic style and the aesthetic content.

The spatial organisation of colored regions is similar to the pictorial composition. Image retrieval based on this specific content is serendipitous. We proposed an approach which does not relies on a segmentation step. Depiction of images are small thumbnails, and the similarity measure is based on the Earth Mover's Distance (Fig. 1). We also developped an adaptative matching criterion which basically adjust the number of similar images returned to the user according to its query (Fig. 2)

- In collaboration with an artist-run center in Montreal, we designed a content management system (CMS) for their website. A demo is visible here. All modifications are disabled in this CMS demo.
- I also designed an internal system to manage their etching collection. This system includes our content-based method on spatial organisation of colors. This demo is visible here.

Since 2009, I participate to the Imagerie du Vivant (IDV) medical image multidisciplinary research group.
Collaborating with Farida Cheriet from "Ecole Polytechnique de Montreal", we study new medical image analysis methods.
