Replace lena8b* image with equivalent non-copyrighted material #175

Closed malaterre closed 2 years ago

malaterre commented 2 years ago

Long story short, I cannot upload lena8b* image to Debian archive since it is copyrighted:

https://lintian.debian.org/tags/license-problem-non-free-img-lenna

Could you please refactor a bit the test suite so that this image is not needed when running make test. Maybe something like:

https://www.tandfonline.com/doi/full/10.1080/09500340.2016.1270881

Of course, I could have #ifdef the code myself, but I wanted to be sure you were aware of the issue yourself.

Thanks for the unit test in 2.3.3

I guess this should work also:

This one has some good alternatives:

Please note that we no longer distribute the following images that were previously available in our database: 4.2.04 (lena), 4.2.02 (tiffany), elaine.512, numbers.512 and testpat.1k. Although these images have played a significant role in the history of image processing, they no longer represent the best examples for future research.
