Résumé
Images acquired using satellites allows the study of the evolution of the earth's surface with a coverage (both spatial and temporal) that is impossible to match by any other technology. Despite this fact, in the case of a natural or industrial disaster, it is generally difficult to propose, in a reasonable delay, impact and da mage assessment using satellite images. Ln this thesis, we propose methods for the detection of abrupt changes. These methods are destined to solve the above mentioned technical problems, and thus satellite images could be fully exploited in the framework of risk and hazard assessment. The algorithms that we have developed are generic with respect to the type, resolution, quantity and the nature of the data, and they offer interesting results in terms of precision and computation time.
