Compression Approaches for the Regularized Solutions of Linear Systems from Large-Scale Inverse Problems
Sergey Voronin, Dylan Mikesell, Guust Nolet
We introduce and compare new compression approaches to obtain regularized solutions of large linear systems which are commonly encountered in large scale inverse problems. We first…
Solving or resolving global tomographic models with spherical wavelets, and the scale and sparsity of seismic heterogeneity
Frederik J. Simons, Ignace Loris, Guust Nolet +6
We propose a class of spherical wavelet bases for the analysis of geophysical models and forthe tomographic inversion of global seismic data. Its multiresolution character allows f…
Nonlinear regularization techniques for seismic tomography
I. Loris, H. Douma, G. Nolet +2
The effects of several nonlinear regularization techniques are discussed in the framework of 3D seismic tomography. Traditional, linear, penalties are compared to so-calle…
Tomographic inversion using -norm regularization of wavelet coefficients
Ignace Loris, Guust Nolet, Ingrid Daubechies +1
We propose the use of regularization in a wavelet basis for the solution of linearized seismic tomography problems , allowing for the possibility of sharp discontinu…
