Sparse Representation of Seismic Data


In this talk, we will present two new methods for sparse representation of geophysical oil/gas exploration data. One is based on double sparse dictionary learning by seislet transform and data-driven tight frame, and another one is based on asymmetric Gaussian chirplet and match pursuit. The data interpolation and denoising will benifit from the sparse transform.
