Learning Interaction-aware3DGaussianSplattingfor One-shotHandAvatars
Existing GS-based methods designed for single subjects often yield unsatisfactory results due to limited input views, various hand poses, and occlusions. To address these challenges, we introduce a novel two-stage interaction-aware GS framework that exploits cross-subject hand priors and refines 3DGaussians in interacting areas. Particularly, to handle hand variations, we disentangle the 3D presentation of hands into optimization-based identity maps and learning-based latent geometric features and neural texture maps.

This implies that M(δ) = T(δ), i.e., the constraint(13) made in T(δ) does not lose any generality in matrix representation. One technical distinction relative to the previous works [2,3] arises from the fact that in our setting, the hamming distances(dx1(`),dx2(`),dx3(`)) defined w.r.t. We focus on the family of rating matrices{Mhci: c T`}. First, we present the following lemma that guarantees the existence of two subsets of users with certainproperties. The proof of this case follows the same structure as that of the grouping-limited regime. It is shown that the groups within each cluster are recovered with a vanishing fraction of errors if Ig = ω(1/n).
