I started my studies in September '91 at the "Politehnica" University of Bucharest. In June '96 I obtained my engineering degree in electronics and telecommunications. During those years I had several opportunities to study in France at ESIEE.

In June'97 I obtained a second engineering degree in signal and image processing from another French school : ENSEEIHT. In the same year I prepared the masters of research : DEA SIC.

Research Interests:

Textured Images Segmentation and Indexing using the Wold Decomposition :

This is a joint research project between INRIA Sophia-Antipolis (France) and Ben-Gurion University (Israel). The directors are Josiane Zerubia (INRIA) and Joseph M. Francos (Ben Gurion University).

Here you have a " demo " ...

Thin network extraction in SPOT images using a stochastic geometry approach. This my PhD subject. My advisors are Xavier Descombes and Josiane Zerubia.

We consider that a thin network is mainly composed of line segments. The segments need to be alligned and not superposed. The segments have to be connected, in order to form a line-network. Those constraint are taken in account by the prior model (Candy model), which is an area-interaction point process.

The location of the network in the image is given by the conditional term. This term is a statistical hypothesis test. The two terms of our model are combined together in an energy function. The optimum of this function is found by runing a simulated anealing algorithm, using a reversible jump MCMC dynamic.

Life is wonderfull, and the last PhD defense of the milenium, it will happen at the end of the century...
