Full textThe volume of digital visual data is increasing dramatically year after year. At the same time, image editing has become easier and more precise. Malicious modifications are therefore more accessible. Image forensics provides solutions to ensure the authenticity of digital visual data. Recognition of the source camera and detection of falsified images are among the main tasks. At first, the solutions were classical methods based on the artifacts produced during the creation of a digital image. Then, as in other areas of image processing, the methods moved to deep learning. First, we present a state-of-the-art survey of deep learning methods for image forensics. Our state-of-the-art survey highlights the need to apply pre-processing modules to extract artifacts hidden by image content. We also highlight the problems concerning image recognition evaluation protocols. Furthermore, we address counter-forensics and present compression based on artificial intelligence, which could be considered as an attack. In a second step, this thesis details three progressive evaluation protocols that address camera recognition problems. The final protocol, which is more reliable and reproducible, highlights the impossibility of state-of-the-art methods to recognize cameras in a challenging context. In a third step, we study the impact of compression based on artificial intelligence on two tasks analyzing compression artifacts: tamper detection and social network recognition. The performances obtained show on the one hand that this compression must be taken into account as an attack, but that it leads to a more important decrease than other manipulations for an equivalent image degradation

Full textThe airlines crew rostering problem considers the assignment of the crew staff to a set of pairings covering all the scheduled flights so that operations costs are minimized while its solution meets hard constraints resulting from the safety regulations and the airlines internal agreements. These constraints contributes to the formulation of a complex combinatorial optimization problem for which a number of exact and approximate methods haven been developed. The approach proposed in this thesis differs from former works by three principal points : the integration of satisfaction degree of the crew members ; the crew rostering problem is dealt in a dynamic context where disturbances lead to modifications for the monthly crew roster planning. So this approach goes well beyond the simple resolution of a mathematical problem and configures a supervision function of the crew assignment process ; the use of techniques of the Artificial Intelligence field : Fuzzy logic and Genetic algorithms. In this study, two main situations are treated : the nominal crew rostering probelm which is elaborated before the beginning of the operation period. The reassignment in a dynamic context where disturbances lead to modifications of the monthly crew roster planning. In the first case, we deal with a combinatorial optimization problem considering simultaneously the two following criteria : the cost-airline associated with the crew assignment and the satisfaction of the crew staff. The solution approach proposed here is composed of two steps : in the first one a GRASP heuristic method is designed to get a first set of high satisfaction assignment solutions and in the second one, an optimization process, based on Genetic Algorithms is developed to minimize the crew assignment cost. A set of not-dominated solutions is then generated. Fuzzy logic is used to estimate the degree of satisfaction of the crew members. In the second case, the solution approach proposed takes into account the dynamic context of the operations which leads to an on-line redefinition of the assignment solutions. The objective consists here in minimizing the number of modifications of the previous planning. A solution scheme close to Dynamic Progamming generates a set of feasible assignment solutions and a Fuzzy Logic approach defines the relevant penalities to be introduced in the decision criterion

Full textThis thesis deals with the parameter identification from the viewpoint of optimization and distributed tracking control of fractional-order multi-agent systems (FOMASs) considering time delays, external disturbances, inherent nonlinearity, parameters uncertainties, and heterogeneity under fixed undirected/directed communication topology. Several efficient controllers are designed to achieve the distributed tracking control of FOMASs successfully under different conditions. Several kinds of artificial intelligence optimization algorithms andtheir modified versions are applied to identify the unknown parameters of the FOMASs with high accuracy, fast convergence and strong robustness. It should be noted that this thesis provides a promising link between the artificial intelligence technique and distributed control
