Packaged_Installer folder contains the MATLAB Runtime which you must install before using any of the software versions.


you can download the full MATLAB Runtime from MATLAB Runtime

In folder Test Data for WISHARTChange a time series of SAR data is available for diagonal dual polarization (VV and VH) in two formats: GeoTIFF and ENVI with header files. The data is acquired from Google Earth Engine (GEE), for more detail see the ReadMe file.

Test Data for MADChange contains two time points of optical images with 4 bands (B2,B3,B4,B8) from GEE in two formats, GeoTIFF and ENVI with a header file.

For more specific detail, see the Software_description.pdf.
