My researchs focus on imagery and I am involved in ICAR team. I tend to develop a combinatorial and discrete approach of imagery. My goal is to provide a complete discret framework to model, analyze and represent digital images. In particular, I'm interested in the definition of a formal digital model of image, in regions segmentation by combinatorial and statistical algorithms, and in the characterization the results by topological data structures and digital geometry features.

In Digital geometry, I studied digital topology in order to have a consistent model to work with. Now, I'm studying digital geometry features such as digital planarity or curvature. I studied combinatorial maps as a graph structure to represent image and model digital structures or segmented images.

In Image Analysis, I proposed to use Union-Find algorithms to segment images efficiently and I am working on statistical merging criteria for these algorithms.

I also have interests in computational complexity, computer arithmetic, cryptography, graph theory and many others in computer science and mathematics...
