In this paper an overview is given on the application of directional basis
functions, known under the name Curvelets/Contourlets, to various
aspects of seismic processing and imaging, which involve adaptive
subtraction. Key concepts in the approach are the use of (i) directional
basis functions that localize in both domains (e.g. space and angle);
(ii) non-linear estimation, which corresponds to localized muting on
the coefficients, possibly supplemented by constrained optimization. We
will discuss applications that include multiple, ground-roll removal and
migration denoising.
