Texte intégralHyperspectral imaging transcribes each specific spectrum of the received energy from a material in a specific pixel of the image. Since heterogeneous land occupation types exhibit different spectral signatures, hyperspectral imaging can be considered as an effective technology for precise image classification. Nevertheless, the temporal variability of spectral signatures complicates the image analysis task due to the interlacement of spectral properties of different land occupation types throughout the year. Standard classification approaches treat each date separately whereas recent research has proven that modelling hyperspectral images incorporating time dimension is crucial. In this dissertation, we propose new methods and algorithms for the classification of time series of hyperspectral images. Our first contribution in the inclusion the temporal dimension into the classical model of spectral signature using the Delaunay reconstruction. This investigation allows us to develop a 3D multi-temporal model of spectral signatures incorporating spectral, temporal and spatial facets of objects. Indeed, we have proposed a new set of spectral signatures based on the above-mentioned model and have developed an appropriate conceptual schema. The database of satellite images is supported by a hierarchical indexing model using Kohonen's Self Organizing Feature Maps. We also studied boosting learning techniques for the selection of the most relevant features. This proposal is based on the Rankboost algorithm. Our second contribution is tackling the problem of mixed pixels in hyperspectral imagery for time series images. Indeed, for the extraction of multi-temporal endmembers, we developed two approaches: a matrix-based approach and a tensor-based approach which has its roots in the multilinear algebra. Moreover, for the purpose of the classification of non-linearly separable data and modelling imperfect data, we used the Fisher discriminant analysis and the Dempster-Shafer theory, respectively. We also proposed a new classification algorithm that is an evidential extension of the discriminant analysis. Our third contribution consists in modelling the spectral unmixing problem as a constrained optimization problem. Experimental results show that the new methods and algorithms proposed in our work improve the classification results compared to standard methods, and thus reveal a real potential for various scenarios of image sequences interpretation

Texte intégralConventional imaging, limited to object shapes and colors, faces limitations in object recognition. To enhance imaging system performance, hyperspectral and polarimetric imaging provides a wealth of information, includingchallenging-to-obtain physical parameters. This facilitates improved object detection, quantitative characterization, and classification. However, the processing of complex data from these modalities remains a challenge. The aim of this work is to propose a generic methodology for the analysis of optical signals, with a primary focus on hyperspectral imaging (HSI). An original classification of invertible physics-based hyperspectral models is presented, along with descriptions of recent diverse models for various applications: MPBOM for algae and bacteria biofilm, MARMIT for soil, PROSPECT for plant leaves, Farrell for turbid biological tissues, Schmitt for human skin, and Hapke for objects in the solar system. A convergence between the PROSPECT and Farrell models for intermediate objects (green apple and leek) paves the way for the development of a new generic and comprehensive modeling approach.Particularly in the field of biology, in collaboration with the ANSES laboratory, we conducted early detection ollowed by quantification of biofilms forming in fish farming basins using hyperspectral and polarimetric imaging. This is crucial as the current visual detection method is not efficient in preventing biofilm accumulation and implementingcleaning and disinfection procedures. Hence, an initial version of a dedicated physical modeling approach called "DNA-HSI" has been established

Texte intégralMulti- and hyper-spectral sensors generate a huge stream of data. A way around thisproblem is to use a compressive acquisition of the multi- and hyper-spectral object. Theobject is then reconstructed when needed. The next step is to avoid this reconstruction and towork directly with compressed data to achieve a conventional treatment on an object of thisnature. After introducing a first approach using Riemannian tools to perform edge detectionin multispectral image, we present the principles of the compressive sensing and algorithmsused to solve its problems. Then we devote an entire chapter to the detailed study of one ofthem, Bregman type algorithms which by their flexibility and efficiency will allow us to solvethe minimization encountered later. We then focuses on the detection of signatures in amultispectral image relying on an original algorithm of Guo and Osher based on minimizingL1. This algorithm is generalized in connection with the acquisition compressed. A secondgeneralization will help us to achieve the pattern detection in a multispectral image. Andfinally, we introduce new matrices of measures that greatly simplifies calculations whilemaintaining a good quality of measurements

A new spectral signature method for hyperspectral images denoising named as hyperspectral non-local mean is proposed in this thesis. This method uses spectral information and spatial information to denoise hyperspectral images. Traditionally, spectral information and spatial information are used separately. Thus, there are two different groups of methods to denoise hyperspectral images, spatial algorithms and spectral algorithms. The spatial denoising methods such as smoothing filter, non-local mean and non-local Bayesian consider the correlation in an image. The spectral denoising methods such as PCA (Principal component analysis), HySime (Hyperspectral subspace identification by minimum error) and MNF (Minimum noise fraction) consider the correlation in spectral. Hyperspectral non-local mean takes the advantages of these two groups of algorithms and processes spectral information and spatial information in the same time. Our contributions are 1) reduction of the processing complexity of algorithm. 2) choice of the proper algorithm parameters according to the properties of hyperspectral images. 3) combination and comparison with state-of-the-art.

Accurate measurement and characterization of fluctuations in the remote sensing data from satellite, airborne or in situ measurement. The adjacency effect increases the reflection of the target pixel from nearby pixels and path scattering. When substances with different spectral properties in the same pixel within the time, there will be mixed pixel. Mixed pixel is not entirely belong to a particular surface features, in order to make image classification more precise, It is necessary to divide into a variety of features in the percentage of pixel. There are many mathematic models and atmospheric correction methods, which could remove the adjacency effect from the satellite and airborne imaginary, but few discusses are made about the influence of adjacency effect on field spectroscopy, especially the variable come from the measure distance, which means the size of the target pixel, and furthermore. As long as the measure distance increases, it may cause the path scattering unpolarized reflectance come from nearby pixels. Owing to the atmosphere and solar irradiance change varyingly in outdoor measurements, the research is indoor test under artificial light source to reduce the effect of uncertainties by measuring the reflectance of light energy from spectroradiometer. We evaluate the influence of pixel sizes on the adjacency effect from different background canopy density and selective absorption by polarizer. In this study, we discuss the contribution from differerent ratio of the vegetation and soil spectral reflectance and spectral characteristics, and the use of polarized lens that filter polarized light outside the pixal to find out the contribution to spectral reflectance, the results show a quadratic function can model its response mode.
