Cauchy priori distribution-based Bayesian AVO reflectivity inversion may lead to sparse estimates that are sensitive to large reflectivities. For the inversion, the computation of the covariance matrix and regularized terms requires prior estimation of model parameters, which makes the iterative inversion weakly nonlinear. At the same time, the relations among the model parameters are assumed linear...
The Hilbert-Huang transform (HHT) is a new analysis method suitable for nonlinear and non-stationary signals. It is very appropriate to seismic signals because they show both non-stationary and nonlinear characteristics. We first introduce the realization of HHT empirical mode decomposition (EMD) and then comparatively analyze three instantaneous frequency algorithms based on intrinsic mode functions...
