IMO 'generic' doesn't have to translate to 'domain-agnostic'. Generic here
means that the individual models used are orthogonal, so it is easy to
combine different representations of these models into working code.
There is the 'Image' container, and there are various 'Pixel' types images
are composed of. Generic means that both models are presented as concepts
(and in fact I'm totally delighted to find the documentation use Concepts
to present them !), making it easy to provide alternative Image and Pixel
I'm working on a library for high-performance signal and image processing
( and I'm looking forward to
trying out GIL's Pixel types with my own Matrix types. That's what 'generic'
is all about !
