vtkMarching Squares Example - dataset..

Could someone point me to the dataset (image) that was used in the following example:

https://lorensen.github.io/VTKExamples/site/Cxx/Modelling/ContourTriangulator/

Or where you find datasets for many of the examples? Thanks.

I believe the datasets for that repository can be fetched using git-lfs.
