Nobody said the Metaverse is VR-only, I literally even said "AR/VR" and called AR out before VR. Did you even read my comment?
Image segmentation wouldn't be used in the Metaverse side of AR. By its very definition, the Metaverse is a "layer" on top of either a VR or AR base. Every object that is superimposed in your view as part of the "metaverse" would be generated. It doesn't need to be segmented, it already is. It doesn't need to be described, its descriptions are already part of its properties.
The only use for segmentation is to identify things in the real world. That has nothing to do with the Metaverse and instead, as I said, "with AR/VR in general". In fact, all of the examples on the page showed examples of segmentation when used in standard AR scenarios. Things like helping you execute a recipe.
