Nice explanation, but do we still need to use Playboy for reference images?

It's just a nude, grow up. And the image used in compression benchmarks only shows her face.

It's interesting that there's so much resistance to stop using this particular image when there are billions of alternatives out there. Lena Forsén herself has asked that people stop using it, which seems like a pretty reasonable request.

Tangent since it is not exclusive to image processing, but When I was studying Fourier Transforms at university I recall that the book "Fourier Series" by Gerogi P. Tolstov helped me a lot. Just throwing it out there in case it helps anyone, including to refresh the definitions the article starts with.

I read this book too and it really drove things home. I remember after feeling a little bit unsure about the relevance of orthogonal systems, feeling the thrill of beginning to see and anticipate where the argument was going. It felt like I was discovering it for myself. I think there are lot of good math and physics books from the Soviet era.

That is indeed a reasonable request. Do you have the source?
