We've found that Burg's two-dimensional filter offers too much freedom in producing lateral predictions, since the predictions within a trace appear to overwhelm the lateral predictions. Instead, we fix the filter coefficients along the output column so the form of the two-dimensional filter becomes equivalent to that of the FX-decon operator. The ability to control the length of this filter in time allows two-dimensional deconvolution to produce a result superior to the FX-decon result. A symmetry for operators calculated forward and backward in space has been found, but it only applies for filters with no free elements in the output column of that filter. The filter shapes of other two-dimensional deconvolution filters are compared and filter shapes that might allow new applications are outlined.
