Xiaohong Chen · Journal of Natural Science of Heilongjiang University · 2012
A total variation regularization method is introduced instead of the traditional Tikhonov regularization method.Based on multiscale methods,a fast and effective multiscale total variation method is designed.For the discontinuous parameters,multiscale total variation regularization method is put forward to improve computational efficiency and accuracy.The numerical results obtained by parameter identification problems for elastic wave inversion show that the proposed multiscale total variation method is stable,faster and accurate.
