Full textAs part of my thesis, I am interested in the issue of creating traditional 2D animations, where all the images are handcrafted. Specifically, I explore how computers can assist artists in producing animations efficiently without reducing the artistic creative process. To address this problem, my work falls within the scope of automatic methods, where the animator collaborates iteratively with the computer. I propose a method that takes two keyframe images and a series of 2D vector fields describing the motion in image space of the animation, and generates intermediate images while preserving the given style as an example. My method combines two manual animation techniques: pose-to-pose and frame-by-frame animation, providing strong control by allowing any generated image to be edited in the same way as the example images provided. My research covers several domains: motion analysis, 2D curve control, mark-based rendering, and paint simulation

Full textThe problems of continuous optimization are numerous, in economics, in signal processing, in neural networks, and so on. One of the best-known and most widely used solutions is the evolutionary algorithm, a metaheuristic algorithm based on evolutionary theories that borrows stochastic mechanisms and has shown good performance in solving problems of continuous optimization. The use of this family of algorithms is very popular, despite the many difficulties that can be encountered in their design. Indeed, these algorithms have several parameters to adjust and a lot of operators to set according to the problems to solve. In the literature, we find a plethora of operators described, and it becomes complicated for the user to know which one to select in order to have the best possible result. In this context, this thesis has the main objective to propose methods to solve the problems raised without deteriorating the performance of these algorithms. Thus we propose two algorithms:- a method based on the maximum a posteriori that uses diversity probabilities for the operators to apply, and which puts this choice regularly in play,- a method based on a dynamic graph of operators representing the probabilities of transitions between operators, and relying on a model of the objective function built by a neural network to regularly update these probabilities. These two methods are detailed, as well as analyzed via a continuous optimization benchmark

Full textIn the domain of satellite networks, the emergence of low-cost interactive terminals motivates the need to develop and implement multiple access protocols able to support different user profiles. In particular, the European Space Agency (ESA) and the German Aerospace Center (DLR) have recently proposed random access protocols such as Contention Resolution Diversity Coded ALOHA (CRDSA) and Irregular Repetition Slotted ALOHA (IRSA). These methods are based on physical-layer network coding and successive interference cancellation in order to attempt to solve the collisions problem on a return channel of type Slotted ALOHA.This thesis aims to provide improvements of existing random access methods. We introduce Multi-Slot Coded Aloha (MuSCA) as a new generalization of CRDSA. Instead of transmitting copies of the same packet, the transmitter sends several parts of a codeword of an error-correcting code ; each part is preceded by a header allowing to locate the other parts of the codeword. At the receiver side, all parts transmitted by the same user, including those are interfered by other signals, are involved in the decoding. The decoded signal is then subtracted from the total signal. Thus, the overall interference is reduced and the remaining signals are more likely to be decoded. Several methods of performance analysis based on theoretical concepts (capacity computation, density evolution) and simulations are proposed. The results obtained show a significant gain in terms of throughput compared to existing access methods. This gain can be even more increased by varying the codewords stamping rate. Following these concepts, we also propose an application of physical-layer network coding based on the superposition modulation for a deterministic access on a return channel of satellite communications. We observe a gain in terms of throughput compared to more conventional strategies such as the time division multiplexing

Full textIn this thesis different trajectory-based methods for the study of quantum mechanical phenomena are developed. The first approach is based on a global expansion of the hydrodynamic fields in Chebyshev polynomials. The scheme is used for the study of one-dimensional vibrational dynamics of bound wave packets in harmonic and anharmonic potentials. Furthermore, a different methodology is developed, which, starting from a parametrization previously proposed for the density, allows the construction of effective interaction potentials between the pseudo-particles representing the density. Within this approach several model problems are studied and important quantum mechanical effects such as, zero point energy, tunneling, barrier scattering and over barrier reflection are founded to be correctly described by the ensemble of interacting trajectories. The same approximation is used for study the laser-driven atom ionization. A third approach considered in this work consists in the derivation of an approximate many-body quantum potential for cryogenic Ar and Kr matrices with an embedded Na impurity. To this end, a suitable ansatz for the ground state wave function of the solid is proposed. This allows to construct an approximate quantum potential which is employed in molecular dynamics simulations to obtain the absorption spectra of the Na impurity isolated in the rare gas matrix

Full textDifferent applications of neural networks for numerical methods are explored, in the context of fluid or plasma simulation.A first application is the learning of a closure for a macroscopic model, based on data from a kinetic model. Numerical results are given for the Vlasov-Poisson equation in 1D and the Boltzmann equation in 2D.A second application is the learning of problem-dependent parameters in numerical schemes. In this way, an artificial viscosity coefficient is learned for a discontinuous Galerkin scheme, and a relaxation matrix for the Lattice-Boltzmann method

Full text[The purpose of this work consists to elaborate methodologies to describe and to compare a ancient handwritten writings. The developed image feature are global and do not require any segmentation. It proposes new robust features based on second order statistics. We introduce the generalized co-occurrence matrix concept which measures the joint probability of any information from the images. This new statistical measure in an extension of the grey level co-occurrence matrix used until now to characterize the textures. We propose spatial co-occurrence matrix relative to the orientations and to the local curvatures of the forms, and parametric matrices which measure the evolution of an image under successive transformations. Because the obtained number of descriptors is very high, we suggest designed methods using eigen co-occurrence matrices in order to reduce this number. In this application part, we propose some clustering methods of medieval writings to test our propositions. The number of groups and their contents depend on used parameters and on applied methods. We also developed a Content Based Image Retrieval system to search for similar writings. Within the framework of the project ANR-MCD Graphem, we elaborate methods to analyse and to observe the evolution of the writings of the Middle Ages. ]

Full textNon-invasive Brain Computer Interfaces (BCIs) allow a user to control a machine using only their brain activity. The BCI system acquires electroencephalographic (EEG) signals, characterized by a low signal-to-noise ratio and an important variability both across sessions and across users. Typically, the BCI system is calibrated before each use, in a process during which the user has to perform a predefined task. This thesis studies of the sources of this variability, with the aim of exploring, designing, and implementing zero-calibration methods. We review the variability of the event related potentials (ERP), focusing mostly on a late component known as the P300. This allows us to quantify the sources of EEG signal variability. Our solution to tackle this variability is to focus on adaptive machine learning methods. We focus on three transfer learning methods: Riemannian Geometry, Optimal Transport, and Ensemble Learning. We propose a model of the EEG takes variability into account. The parameters resulting from our analyses allow us to calibrate this model in a set of simulations, which we use to evaluate the performance of the aforementioned transfer learning methods. These methods are combined and applied to experimental data. We first propose a classification method based on Optimal Transport. Then, we introduce a separability marker which we use to combine Riemannian Geometry, Optimal Transport and Ensemble Learning. Our results demonstrate that the combination of several transfer learning methods produces a classifier that efficiently handles multiple sources of EEG signal variability
