This paper addresses the problem of image-based surface reconstruction. The main contribution is the computation of the exact derivative of the reprojection error functional. This allows its rigorous minimization via gradient descent surface evolution. The main difficulty has been to correctly take into account the visibility changes that occur when the surface moves. A geometric and analytical...

To my parents and siblings. Acknowledgments The past three years as a PhD student have been interesting, exciting and enjoyable. For that, I thank my adviser Dale Miller very much. He provided me with wise scientific advice, and has always been available for interesting discussions. It has been a good fortune and a pleasure to work with Dale. I learned a lot from him and I hope that that our co...

Détermination des forces de traction au cours de la migration de cellules cancéreuses sur des gels

The migration process is a physically integrated molecular phenomena that contributes to many physiological motility in vivo processes such as development, immune surveillance and cancer metastasis. To understand cell migration it is necessary to consider the cell’s environment, cell type and morphology as well as the internal organization of the cells, i.e. its cytoskeleton and focal adhesions...
