Simultaneous shot inversion for nonuniform geometries using fast data interpolation [article]

Michelle Liu, Rajiv Kumar, Eldad Haber, Aleksandr Aravkin
2018 arXiv   pre-print
The approach is formulated as a joint inverse problem, combining ideas from low-rank interpolation with full-waveform inversion.  ...  Using 'simultaneous shots', or random superposition of source terms, works very well in simple acquisition geometries where all sources see all receivers, but this rarely occurs in practice.  ...  R.K. would like to thank the member organizations of the SINBAD II project and the SINBAD Consortium for supporting this work.

A Visualization Architecture for Collaborative Analytical and Data Provenance Activities

Aqeel Al-Naser, Masroor Rasheed, Duncan Irving, John Brooke
2013 2013 17th International Conference on Information Visualisation  
Given the nature of intuition, this can be a source of differing interpretations depending on the human expert; thus we do not have a single feature but multiple views of a feature.  ...  When exploring noisy or visually complex data, such as seismic data from the oil and gas industry, it is often the case that algorithms cannot completely identify features of interest.  ...  Examples of such data are found in medical imaging and in the field that is the topic of this paper, interpretation of geophysical seismic imaging data [1] .  ...
