W-3 Compressive Sensing and Computation Date: Thursday, 22 September Description: Seismic exploration relies on the collection of massive amounts of data which are mined for information during processing. While this approach has, historically, been extremely successful, increasing pressure to explore in more and more complicated regions of the Earth, coupled with the advent of wide azimuth seismic, has led to the acquisition and processing of larger and larger data volumes. Further, as the volume of data collected has grown, so have the costs associated with it. These costs are exacerbated by Nyquist's sampling criterion, which disproportionately strains current acquisition and processing systems as the size and desired resolution of our survey areas continues to increase. Compressive sensing offers an alternative sampling strategy, one that leverages recent developments in sparsifying transforms and convex optimization. This approach opens a concrete perspective towards a new technology where acquisition and processing costs are no longer inflated by an overly stringent sampling criterion. Schedule:
