Seismic Trace Interpolation using Weighted L1 Minimization

This application is available only in the software release for members of SINBAD consortium.

This software release includes a demonstration of the wavefield reconstruction framework in Matlab that has been developed at SLIM.

Author: Hassan Mansour

Date : April, 2013


Downloading & Dependencies

The code can be found in the SLIM sofware release under /applications/Processing/WeightedL1Interpolation.

The code has been tested with Matlab R2012b.

This code uses the following packages, also found in the tools part of the SLIM software release.

Running & Parallelism

All the examples and results are produced by the scripts found in this software release under applications/Processing/WeightedL1Interpolation/. Start matlab from that directory or run startup in that directory to add the appropriate paths.

To run the scripts follow the instructions in the README file enclosed with the code. The scripts can be run in serial mode.

Scripts, examples and results

Several scripts that reproduce the interpolation results in [1] can be found in the exps directory.

More detailed descriptions and some basic tests are described in wL1_freq_MH.m and wL1min.m.

The results are shown here.
