ABSTRACT
In this article, we present an extension of the Fast Discrete Curvelet Transform (FDCT) to non-uniformly sampled data, NFDCT. With this extension to non-uniform grids, we are able to not only restore curvelet compression rates for non-uniformly sampled data but also remove noise and map the data to a regular grid.
INDEX TERMS
noise, signal interaction, nonuniform Fourier transform, overcomplete signal representation, multiscale transform, shrinkage, denoising, curvelet transform, seismic processing
