May 7, 2021 · We propose a basis pursuit inversion (BPI) extended to VTI media, where: 1) we decompose the five elasticities into basis pursuit pairs by a dipole ...
We propose a prestack high-resolution inversion based on a BPI scheme for VTI media, where we introduce the L1–L2 sparser norm [25] as constraint. The ...
Sparsity constraints have been widely adopted in the regu- larization of ill-posed problems to obtain subsurface proper- ties with sparseness features.
Synthetic tests suggest that a sparse-layer inversion using basis pursuit can better resolve thin beds than a comparable sparse-spike inversion. Application to ...
Oct 22, 2024 · A basis pursuit inversion of seismic reflection data for reflection coefficients is introduced as an alternative method of incorporating a ...
Nov 4, 2014 · Un- like conventional deconvolution methods, the BPD uses an L1 norm constraint on model reflectivity to impose sparsity. In addition, it uses ...
We proposed a novel L 1 -L 2 norm regularization via the forward-backward splitting method for enhancing the FMT reconstruction accuracy and the robustness.
