Michel Jourlin was born in Saint-Etienne, France, and graduated in Mathematics at the University of Lyon 1. After a PhD in Pure Mathematics, he turned his research towards Image Processing. His most important contribution is the development of the LIP (Logarithmic Image Processing) Model, which offers a particularly efficient framework for Biomedical and Industrial Image Processing, due to its strong physical and mathematical properties added to its consistency with the Human Visual System. This last point favors the automated interpretation of images by means of a computer, while preserving a high correlation with human expertise. After ten years as Scientific Director of the Engineer School CPE-Lyon, Michel Jourlin is currently Full Professor at the University of Saint-Etienne and develops his research at the CNRS Laboratory Hubert Curien.
