Waveform Reconstruction Imaging

This software release includes a demonstration of the parallel Wavefield reconstruction Imaging algorithm in Matlab that has been developed at SLIM.

Author: Bas Peters Date : April, 2014


Downloading & Dependencies

The code can be found in the SLIM sofware release under |/applications/Imaging/WRimaging.

The code has been tested with Matlab R2013a and requires the Parallel Computing Toolbox.

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/Imaging/WRimaging/. Start matlab from that directory or run startup in that directory to add the appropriate paths.

To run the scripts follow the instrictions in the README file enclosed with the code.
