There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
In this dissertation, we design a framework that interactively delineates important geological structures such as faults and salt domes in seismic volumes. Within the seismic volume, we divide seismic sections into two classes, reference and predicted ones. In reference sections, we implement interpreter-assisted workflows that delineate faults and salt domes using their geometric representations and texture features. Then, we introduce automated tracking workflows that delineate target structures in predicted sections by tracking corresponding labeled results in reference sections through the seismic volume. To ensure accurate tracking, we extract features along geological structures using tensor-based subspace learning methods. Experimental results on real seismic data sets show that our interactive interpretation framework outperforms state-of-the-art methods in terms of accuracy and efficiency.
