A texture that should have easily tagged, but is not even close.

I'm trying to use this software to organize my texture asset library, but the
AI models can only identify objects, not textures, so I'm getting gibberish
instead.


STEPS TO REPRODUCE
1. Get a few textures (3D Total has a bunch of free packs for example).
2. Put them in your library and make DigiKam scan them to add automatic tags (I
used the slowest YOLOv5 XLarge).
3. Check the tags that it has automatically added.


OBSERVED RESULT
It identifies a wood texture as "person, car, pastry, ...", just as an example.
Basically, if there is no visible silhouette of an object, it invents the tags,
and even when there is a full object, it has issues if it's lacking context.


EXPECTED RESULT
The model should try to interpret the patterns and color of the texture to
understand what material could it be.


SOFTWARE/OS VERSIONS
Windows: 
macOS: 
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: 
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
Searching a bit online I've found Clarifai and Nyckel may be able to do that, I
don't know if they could be integrated into DigiKam, and if so, how to do it.
Nyckel at least offers API access, but I don't know how it works.
If you need some testers I could help, my library is over 60GB with textures of
all kinds of materials from all over the world, higher and lower quality,
non-tileable and seamless, photoreal and digital, materials and effects, all
you can ask for, I probably have.
