Seismic imaging techniques play a crucial role in the exploration and understanding of subsurface structures. In the field of petroleum exploration, subsalt zones present a challenge for conventional imaging techniques and full-wave inversion (FWI). The application of FWI to seismic well data is expected to overcome these challenges. The primary goal is to characterize hydrocarbon reservoirs that may be located beneath and alongside salt bodies. However, the context of well seismic imaging, combined with the challenges of imaging beneath and around salt bodies, requires the introduction of strong constraints into the geophysical inverse problem due to its underdetermined nature.This thesis presents a three-step approach to tackle these challenges. Firstly, it suggests incorporating extit{a priori} geological information into the inversion process by defining geological objects bounded by discontinuities. Secondly, it aims to formalize and compute the gradient with respect to the geometric parameters that define these discontinuities. Thirdly, it proposes the implementation of a hybrid full-wave inversion algorithm that combines field and object-based approaches. This hybrid FWI utilizes both the gradient of physical fields and the gradient relative to geometric parameters.The thesis content is divided into four distinct chapters. The first chapter introduces the fundamental concepts used in the hybrid FWI algorithm. It highlights the approach based on a dual representation of interfaces (explicit/implicit) using deformable unstructured meshes for the explicit discretization of discontinuities and the level-set method for the implicit representation of the geological objects in the inverse problem. Chapter 2 describes the development steps of a software platform for the numerical implementation of these approaches and the execution of hybrid FWI tests. This software platform includes a wave propagation modeling code based on the spectral elements method and an inversion code based on the gradient computation using the Green's function method, with a probabilistic approach to the inverse problem. The third chapter outlines the various stages of the geometric FWI algorithm and its application to well seismic data to estimate the position of salt/sediment interfaces in 2D environments. Finally, the fourth chapter presents the hybrid inversion algorithm and its implementation with well seismic data to estimate the velocities of compression and shear waves, as well as the position of salt body boundaries in 2D environments. The results of the presented numerical tests are promising, validating our hybrid inversion approach

With the advancement of remote sensing technology, the applications of hyperspectral imagery (HSI) are more and more popular. Despite of many success achieved by HSI techniques, there are still some problems to be solved. For instance, HSI data provides huge information which usually contains a lot of redundancy because of its inherent nature. It imposes difficulties for classification because of the curse of dimensionality issue. The enormous data volume of HSI also causes the issues of data storage and long processing time. Therefore, how to select the representative bands from the original image cube without significant loss of information is one of the most important topics in remote sensing society. We call it Band Selection (BS). In this thesis, we combine a new concept, Band Subset Selection (BSS), with self-sparse representation (SSR) model as the objective function, to create an effective BS method for data dimensionality reduction. This method is called self-sparse representation based BSS (SpaBSS). In order to efficiently implement SpaBSS, two iterative algorithms are developed: successive SpaBSS (SC-SpaBSS) and sequential SpaBSS (SQ-SpaBSS). Unlike many existing BS approaches which may only find the locally optimal solution by a single path, the proposed SpaBSS can obtain the nearly globally optimal solution by continuously updating the band subset based on minimizing the reconstruction error of SSR model. The experiments conducted on three real hyperspectral datasets demonstrate that both SpaBSS methods can find appropriate band subsets for effective hyperspectral image classification and endmember extraction.
