f Monoplane filter and applications

Seismic data routinely exhibits conflicting dips where as an ideal seismic image has only one dip at each location. Here I introduce an objective measure of the presence of more than a single dip, This measure is the output of a local filter with enough degrees of freedom that it is able to extinguish a single plane wave but not enough degrees of freedom to extinguish more than one plano. This filter is called a LOcal MOnoPLane ANnihilator (LOMOPLAN). Figure 1 shows a synthetic model and the outputs of an array of LOMOPLANs applied to it. Outputs are patched together to smooth over the seams defining the many local regions.
