Abstract
We present a non-linear method for solving linear inverse problems by thresholding coefficients in the
wavelet domain1. Our method is based on the wavelet-vaguelette decomposition of Donoho (1992).
Numerical results for a synthetic travel-time inversion problem show that the wavelet based method
outperforms traditional least-squares methods of solution.
