How can i get background removed result?

[hanjoonwon]

I don't want to reconstruct the background, just the object. Which pipeline option should I use to achieve the desired result?

For the nerf models, like nerfacto, just make sure you add masks when training. Here you can read more about the mask conventions in nerfstudio. For gsplatfacto/gaussian-splatting the masks are a bit hacky right now, making the gaussians within the masked out regions just black so you could try remove them as a post-processing step.

You can also try Nerf-in-the-wild to change the background of the NeRF since it has appearance embeddings for it.
