Global seismic tomography with sparsity constraints: Comparison with smoothing and damping regularization
JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, pp. 4887-4899, 2013.
We present a realistic application of an inversion scheme for global seismic tomography that uses as prior information the sparsity of a solution, defined as having few nonzero coefficients under the action of a linear transformation. In this paper, the sparsifying transform is a wavelet transform. We use an accelerated iterative soft-thr...More
