IGUG: A MATLAB package for D inversion of gravity data using graph theory
Saeed Vatankhah, Vahid Ebrahimzadeh Ardestani, Susan Soodmand Niri +2
The open source MATLAB package IGUG for 3D inversion of gravity data is presented. It is based on methodology that was introduced by Bijani et al (2015), in which a homogeneous sub…
Total variation regularization of the -D gravity inverse problem using a randomized generalized singular value decomposition
Saeed Vatankhah, Rosemary A. Renaut, Vahid E. Ardestani
We present a fast algorithm for the total variation regularization of the -D gravity inverse problem. Through imposition of the total variation regularization, subsurface struct…
A fast algorithm for regularized focused 3-D inversion of gravity data using the randomized SVD
Saeed Vatankhah, Rosemary A. Renaut, Vahid E. Ardestani
A fast algorithm for solving the under-determined 3-D linear gravity inverse problem based on the randomized singular value decomposition (RSVD) is developed. The algorithm combine…
3-D Projected inversion of gravity data
Saeed Vatankhah, Rosemary A. Renaut, Vahid. E. Ardestani
Sparse inversion of gravity data based on -norm regularization is discussed. An iteratively reweighted least squares algorithm is used to solve the problem. At each iteration…
