plus Abstract :

The subject of my internship is 3D reconstruction using "Shape from Shading". The problem is modelized with a global energy function whose global minimum is the optimal solution. A diffusion process in combination with simulated annealing is considered to find this global minimum. In a first part, I have to modify the energy function due to a change of the underlying assumptions of the problem, i.e. switching from the orthographic projection to the perspective projection camera model. Furthermore, I will also evaluate some modifications to the optimization process to increase the convergence speed.
