# What is “natural image domain”?

I see some papers use the term "natural image domain". I googled that but didn't find any explanation of it.

I guess I understand the normal meaning of "natural image", such as the image people take by phones. The images in ImageNet database are all natural images.

Is "natural image domain" a subfield of computer vision?
