Testo completoIdentifying the perpetrator of arson is a real challenge of criminal investigation since the physical traces associating a perpetrator with this type of crime scene are often destroyed by fire or extinguishing procedures. If an ignitable liquid was used to start the fire, and its residual presence can be detected, a source inference approach with other ignitable liquids is likely to provide investigative or evidentiary support. Source inference is a process of association, a method that consists of evaluating the possible common source between two unknown (traces of) ignitable liquids, in particular between a trace of a liquid extracted from a sample taken at the scene of the fire and a liquid found outside the scene (jerrycan found nearby, suspect's clothing...). While previous work has shown that it is possible to link two altered or unaltered ignitable liquids sharing a common source by source inference thanks to similarity calculation algorithm, it remains difficult to extend this to ignitable liquid residues in fire debris frequently received at the laboratory. In this work, we propose to study the contribution of matrices to the problem of source inference, using multivariate chemometric methods developed previously. The matrix chosen was clothing, little studied until now, but often found at fire scenes. The approach was then applied to a reduced sampling of unaltered gasoline and an undegraded matrix, followed by a substantial sampling of gasoline altered by evaporation on an undegraded matrix and then altered by combustion simultaneously on the same matrix. Evaluation of the results obtained validated the general hypothesis that it is possible to link weathered and unweathered gasoline samples, independently of the mode of weathering by evaporation or combustion and in the presence of matrix effects

Testo completoThis thesis is devoted in a first part to the elaboration of a second order variational modelfor image denoising, using the BV 2 space of bounded hessian functions. We here take a leaf out of the well known Rudin, Osher and Fatemi (ROF) model, where we replace the minimization of the total variation of the function with the minimization of the second order total variation of the function, that is to say the total variation of its partial derivatives. The goal is to get a competitive model with no staircasing effect that generates the ROF model anymore. The model we study seems to be efficient, but generates a blurry effect. In order to deal with it, we introduce a mixed model that permits to get solutions with no staircasing and without blurry effect on details. In a second part, we take an interset to the texture extraction problem. A model known as one of the most efficient is the T V -L1 model. It just consits in replacing the L2 norm of the fitting data term with the L1 norm.We propose here an original way to solve this problem by the use of augmented Lagrangian methods. For the same reason than for the denoising case, we also take an interest to the T V 2-L1 model, replacing again the total variation of the function by the second order total variation. A mixed model for texture extraction is finally briefly introduced. This manuscript ends with a huge chapter of numerical tests
