Application to the MIRI-MRS infrared spectrometer of the James Webb Space Telescope ». Electronic Thesis or Diss., université Paris-Saclay, 2021. http://www.theses.fr/2021UPASG087.
Texte intégralThis thesis deals with inverse problem approaches to reconstruct a 3D spatio-spectral image from a set of 2D infrared measurements provided by the Integral Field Spectrometer (IFS) instrument (Mid-Resolution Spectrometer: MRS) of the Mid-Infrared Instrument onboard the James Webb Space Telescope. The reconstruction is challenging because the IFS involves complex components that degrade the measurements: (1) the responses of the components are not perfect and introduce a wavelength-dependent spatial and spectral blurring, (2) the instrument considers several observations of the input with several spatial and spectral fields of views, (3) the output measurements are projected onto multiple 2D detectors and sampled with heterogeneous step sizes. The 3D image reconstruction is an ill-posed problem mainly due to spatio-spectral blurring and insufficient spatial sampling. To compensate for the loss of spatial information, the MRS allows multiple observations of the same scene by shifting the telescope pointing, leading to a multi-frame Super-Resolution (SR) problem. We propose an SR reconstruction algorithm that jointly processes the spatial and spectral information of the degraded 2D measurements following two main steps. First, we design a forward model that describes the response of the IFS instrument as a series of mathematical operators and establishes a relationship between the measurements and the unknown 3D input image. Next, the forward model is used to reconstruct the unknown input.The reconstruction is based on the regularized least square approach with a convex regularization for edge-preserving. We rely on the fast half-quadratic approaches based on Geman and Reynolds formulation to solve the problem. The proposed algorithm mainly includes a fusion step of measurements from different spatio-spectral observations with different blur and different sampling, a multi-frame Super-Resolution step from the different pointing of the instrument, and a deconvolution step to minimize the blurring. Another forward model for the same instrument is also developed in our work, by assuming that the 3D input image lives in a low dimensional subspace and can be modeled as a linear combination of spectral components, assumed known, weighted by unknown mixing coefficients, known as the Linear Mixing Model (LMM). We then rely on the Majorize-Minimize Memory Gradient (3MG) optimization algorithm to estimate the unknown mixing coefficients. The subspace approximation reduces the number of the unknowns. Consequently, the signal-to-noise ratio is increased. In addition, the LMM formulation with known spectral components allows preserving the complex spectral information of the reconstructed 3D image. The proposed reconstruction is tested on several synthetic HS images with different spatial and spectral distributions. Our algorithm shows a clear deconvolution and a significant improvement of the spatial and spectral resolutions of the reconstructed images compared to the state-of-art algorithms, particularly around the edges

Texte intégralDue to the recent emergence of new modalities, the amount of signals collected daily has been increasing. As a result, it frequently occurs that various signals provide information about the same phenomenon. However, a single signal may only contain partial information about this phenomenon. Multimodal data fusion was proposed to overcome this issue. It is defined as joint processing of datasets acquired from different modalities. The aim of data fusion is to enhance the capabilities of each modality to express their specific information about the phenomenon of interest; it is also expected from data fusion that it brings out additional information that would be ignored by separate processing. However, due to the complex interactions between the modalities, understanding the advantages and limits of data fusion may not be straightforward.In a lot of applications such as biomedical imaging or remote sensing, the observed signals are three-dimensional arrays called tensors, thus tensor-based data fusion can be envisioned. Tensor low-rank modeling preserves the multidimensional structure of the observations and enjoys interesting uniqueness properties arising from tensor decompositions. In this work, we address the problem of recovering a high-resolution tensor from tensor observations with some lower resolutions.In particular, hyperspectral super-resolution (HSR) aims at reconstructing a tensor from two degraded versions. While one is degraded in two (spatial) modes, the second is degraded in the third (spectral) mode. Recently, tensor-based approaches were proposed for solving the problem at hand. These works are based on the assumption that the target tensor admits a given low-rank tensor decomposition. The first work addressing the problem of tensor-based HSR was based on a coupled canonical polyadic (CP) decomposition of the observations. This approach gave rise to numerous following reconstruction methods based on coupled tensor models, including our work.The first part of this thesis is devoted to the design of tensor-based algorithms for solving the HSR problem. In Chapter 2, we propose to formulate the problem as a coupled Tucker decomposition. We introduce two simple but fast algorithms based on the higher-order singular value decomposition of the observations. Our experiments show that our algorithms have a competitive performance with state-of-the-art tensor and matrix methods, with a lower computational time. In Chapter 3, we consider spectral variability between the observations. We formulate the reconstruction problem as a coupled block-term decomposition. We impose non-negativity of the low-rank factors, so that they can be incorporated into a physically-informed mixing model. Thus the proposed approach provides a solution to the joint HSR and unmixing problems.The second part of this thesis adresses the performance analysis of the coupled tensor models. The aim of this part is to assess the efficiency of some algorithms introduced in the first part. In Chapter 4, we consider constrained Cramér-Rao lower bounds (CCRB) for coupled tensor CP models. We provide a closed-form expression for the constrained Fisher information matrix in two scenarios, whether i) we only consider the fully-coupled reconstruction problem or ii) if we are interested in comparing the performance of fully-coupled, partially-coupled and uncoupled approaches. We prove that the existing CP-based algorithms are asymptotically efficient. Chapter 5 addresses a non-standard estimation problem in which the constraints on the deterministic model parameters involve a random parameter. We show that in this case, the standard CCRB is a non-informative bound. As a result, we introduce a new randomly constrained Cramér-Rao bound (RCCRB). The relevance of the RCCRB is illustrated using a coupled block-term decomposition model accounting for random uncertainties

Texte intégralBesides the chemical information, chemical imaging also offers insights in the spatial distribution of the samples. Within this thesis, we distinguish between two different types of images: spatial-temporal images (super-resolution fluorescence microscopy) and spatial-spectral images (unmixing). In early super-resolution fluorescence microscopy, a low number of fluorophores were active per image. Currently, the field evolves towards high-density imaging that requires new ways of analysis. We propose SPIDER, an image deconvolution approach with multiple penalties. These penalties directly translate the properties of the blinking emitters used in super-resolution fluorescence microscopy imaging. SPIDER allows investigating highly dynamic structural and morphological changes in biological samples with a high fluorophore density. We applied the method on live-cell imaging of a HEK-293T cell labeled with DAKAP-Dronpa and demonstrated a spatial resolution down to 55 nm and a time sampling of 0.5 s. Unmixing hyperspectral images with MCR-ALS provides spatial and spectral information of the individual contributions in the mixture. Due to loss of the pixel neighborhood during the unfolding of the hyperspectral data cube to a two-way matrix, spatial information cannot be added as a constraint during the analysis We therefore propose an alternative approach in which an additional refolding/unfolding step is performed in each iteration. This data manipulation allows global spatial features to be added to the palette of MCR-ALS constraints. From this idea, we also developed several constraints and show their application on experimental data
Raynaud, Christophe. « Spectroscopie d'absorption et d'émission des excitons dans les nanotubes de carbone ». Thesis, Sorbonne Paris Cité, 2018. http://www.theses.fr/2018USPCC199/document.
Texte intégralThe optical properties of carbon nanotubes are ideally described by the physicsof a one-dimensional object, giving rise in particular to the emergence of excitons todescribe the optical transitions of these objects. The optical experiments (emission,absorption) carried out on these objects at ambient temperature and on ensemblesconfirm the theoretical predictions based on the physics of 1D objects. But atcryogenic temperature and at the single emitter scale, the optical properties observedexperimentally are systematically different from those of a 1D object. One can citethe emergence of properties such as photon antibunching, which largely contributed tothe intensification of research on these objects for applications in quantum photonics.These properties are attributed to the localization of excitons along the nanotube axisin local potential wells (traps) created randomly by the interaction of nanotubes withtheir environment. The optical properties are then close to those of 0D objects, andare strongly modulated by the environment. The mechanisms and the origin of thelocalization and the physical knowledge of these traps are still very limited. This workshows on the one hand the development of an absorption setup on individual objectand the characterization of its sensitivity, and on the other hand the statistical studyof the emission of nanotubes at cryogenic temperature in a micro-photoluminescencesetup. The results obtained in the later setup by a super-resolution technique coupledwith hyper-spectral imaging show the characteristic quantities of potential wellswithin individual nanotubes. An experimental excitation-resolved photoluminescencesetup implemented during this work also showed a modification of the fundamentalexcitonic state by the environment, with the emergence of a spatial and spectraldiscretization of the delocalized ground state in a multitude of localized states

In recent years, fusing a low-spatial-resolution hyperspectral image with a highspatial-resolution multispectral image has been thought of as an economical approach for obtaining high-spatial-resolution hyperspectral image. A fusion criterion, termed coupled nonnegative matrix factorization (CNMF) has been reported to be effective in yielding promising fusion performance. However, the CNMF criterion amounts to an ill-posed inverse problem. In this thesis, we propose a new data fusion algorithm by suitable regularization that significantly outperforms the unregularized CNMF algorithm. Besides utilizing the sparsity-promoting regularizer, which promotes the sparsity of the abundance map, we also incorporate the sum-of-squared endmember distances demoting regularizer. Owing to the bi-convexity of the formulated optimization problem, we can decouple it into two convex subproblems. Each subproblem is then solved by a carefully designed alternating direction method of multiplers (ADMM), leading to a convex-optimization based CNMF (CO-CNMF) fusion algorithm, where each ADMM iterate is equipped with a closed-form solution. Since the problem size is very large, leading to high computational complexity of the proposed CO-CNMF algorithm, we futher obtain alternative expressions by exploiting some inherent matrix structure in those closed-form solutions, which greatly reduce the computational complexity. Finally, we present some experiments using real hyperspectral data, which can be divided into three parts. The first part is to analyze how we choose parameters in our proposed algorithm. Second, we demonstrate its superior performance to some state-of-the-art fusion algorithms. Third, by some experimental results, we discuss its performance loss due to imperfect co-registration.
