Kornia is mainly the operations vision models are built and trained from, written to sit inside a network, but it also ships ready pretrained models, including SAM, which segments whatever the user points at in any image with no training. Bundling that kind of model is what places Ultralytics here too. Kornia's models are ports of other projects' networks, and the project has stopped adding them.
