Structure Label Prediction Using Similarity-Based Retrieval and Weakly-Supervised Label Mapping

no code implementations16 May 2019 Yazeed Alaudah, Motaz Alfarraj, Ghassan AlRegib

By having an interpreter select a very small number of exemplar images for every class of subsurface structures, we use a novel similarity-based retrieval technique to extract thousands of images that contain similar subsurface structures from the seismic volume.

Petrophysical Property Estimation from Seismic Data Using Recurrent Neural Networks

no code implementations24 Jan 2019 Motaz Alfarraj, Ghassan AlRegib

Recent advances in machine learning have shown promising results for recurrent neural networks (RNN) in modeling complex sequential data such as videos and speech signals.

Multiresolution Analysis and Learning for Computational Seismic Interpretation

1 code implementation24 Jan 2019 Motaz Alfarraj, Yazeed Alaudah, Zhiling Long, Ghassan AlRegib

Moreover, directional multiresolution attributes, such as the curvelet transform, are more effective than the non-directional attributes in distinguishing different subsurface structures in large seismic datasets, and can greatly help the interpretation process.

Content-adaptive non-parametric texture similarity measure

1 code implementation5 Nov 2018 Motaz Alfarraj, Yazeed Alaudah, Ghassan AlRegib

In this paper, we introduce a non-parametric texture similarity measure based on the singular value decomposition of the curvelet coefficients followed by a content-based truncation of the singular values.
