BOORU YOLO training image set for AA model

This is a snapshot of training image dataset for general torso components model AA (a part of BOORU YOLO project, inspect README for details) as of middle 2025. This model help to define scene scale, character(-s) position and pose and also can distinguish naked body.

Directory structure and label format are default for Ultralitics File naming refer to source image on imageboard and provides dispersion of similar images. 138.816 image+labels pairs (no background images) clustered to 10+10 uniform ZIPs. Image longer side moslty within 800..1600px This is not an exact dataset for AA22 model included, some minor cleanup and adjustments applied after.

Due to project scope and classes nature this dataset :

• focused on anime_art / CG / cartoon images, no real life images used at all
• has a substantial share of furry incl. non-humanoid creatures (dragons, pony etc)
• is certainly NSFW (but not contain straight sex scenes - absolutely no exposed penises, gaping and bodily fluids are very rare)

Some SFW subset of images from here may be browsed (or even directly used) on Ultralitics HUB
