Before my PhD

Paul Sabatier University (1998-2003)

I have done my B.Sc. and M.Sc. at Paul Sabatier University (Toulouse 3, France), between September 1998 and June 2003. This page contains some reports from my work at this time. The reports are written in French but the abstacts are translated in English for non-French speakers.

M.Sc. degree in Computer Science applied to Image and Langage Processing (Master 2)

Training course - Multi-scale analysis of the texture in 2D images (2003): A state of the art of texture analysis methods in numerical images is first presented. Multiscale methods are of special interest in this report. A segmentation algorithm for areal images using wavelet decompositions is then presented. This algorithm is applied to the segmentation of canopy images, where the information contained in the texture is relevant. The segmentation program was written in C.

B.Sc. / M. Sc. degree in Mathematical Engineering (Licence 1,2,3 and Master 1)

Training course - Multimodal 3D image registration using mutual information (2002): In this work, a program of 3D rigid registration of T1/T2 MR images was developed and tested. The program was written in Matlab with MEX file routines in C++. We used the mutual information as a similarity measure between the registered images. Three different optimization methods were tested: The downhill simplex, the steepest gradient descent and the Powells method.

Training course - 3D reconstruction of 2D images representing hand gestures under biomechanical constrains (2002): The goal of this training course was to develop a method able to automatically interpret 2D images representing several hand gestures. The problem was solved using heuristics, morphologic operators and geometric calculations. A program was written in C++ and in Matlab. This program interprets 2D images and rebuild them in 3D using vrml files.

Numerical simulation project - Finite element method for the resolution of an ODE (2002).

Numerical simulation project - Crank Nicolson method for the resolution of a non-stationary PDE (2002).
