Seismic migration using the complex shiftable Pyramid Truong Nguyen (Ecole des Mines de Paris) and Hervé Chauris (Ecole des Mines de Paris) SUMMARY____________________________________________________________ We consider how the 2-D seismic Kirchhoff migration scheme can benefit from a recently introduced shiftable directional pyramid. First the pyramidal dual-tree directional filter bank is presented with some modifications to make it more suitable to the seismic migration problem. Since the decomposition by this filter bank is multiresolution and multidirectional it can be regarded as a digital curvelet transform. We implement the first-order approximation of the Kirchhoff migration scheme. It essentially consists of a rotation a
