Title:
Decoupled deblurring filter and its application to elastic migration and inversion
Authors:
Feng, Zongcai; Schuster, Gerard T. ( 0000-0001-7532-1587 ) ; Dai, Wei
Abstract:
We present a decoupled deblurring filter that approximates the multiparameter Hessian inverse by using local filters to approximate its submatrices for the same and different parameter classes. Numerical tests show that the filter not only reduces the footprint noise, balances the amplitudes and increases the resolution of the elastic migration images, but also mitigates the crosstalk artifacts. When used as a preconditioner, it accelerates the convergence rate for elastic inversion.
