Remarks:

The reference implementation is taken from here, and currently unlicensed. The code itself is an adaptation of the official reference-code provided by MVTec.

If this prevents merging the PR, I would suggest removing the code and the corresponding tests from the unit-tests.

Thanks @ORippler for adding this!

The test scripts do not seem to follow the code-quality standards, but it's ok for now. We don't check the tests at the moment, which we need to refactor quite soon.

Thanks for making this PR! I have a single concern regarding the license.
