Having had good fortune here introducing the anti-causal PEF and earlier
explicitly estimating a portion of the data not fitting the convolutional
model (Zhang and Claerbout, 2010) , it is natural to try introducing both
at the same time. That takes into
account the fact that a part of the input data does not fit the convolution model:
(9)
(10)
in both matrices on the upper left is the data convolution operator,
and
are
the filters, and
and
are
the reflectivity models. The parameter
indicates the strength of the
regularization. We apply the hybrid norm on model residuals
and
to enforce
sparseness. Although the extra parameter tuning (
) is undesirable, we expect
to get more successful result using this more advanced formulation.
