FastAvatar: Instant 3D Gaussian Splatting for Faces from Single Unconstrained Poses
Hao Liang, Zhixuan Ge, Soumendu Majee +4
We present FastAvatar, a fast and robust algorithm for single-image 3D face reconstruction using 3D Gaussian Splatting (3DGS). Given a single input image from an arbitrary pose, Fa…

Distributions In, Distributions Out: The Case for Soft-Label Training
Agamdeep Singh, Ashish Tiwari, Hosein Hasanbeig +1
Supervised classifiers output a distribution over classes but are typically trained against a single label obtained by collapsing multiple annotators into a majority vote. On tasks…

Generating non-diffracting bottle beams with a flat multi-level diffractive lens
Andra Naresh Kumar Reddy, Srinivasa Rao Allam, Ashish Tiwari +4
We introduce a novel method for creating a high-quality, sharply defined, non-diffracting optical bottle beam by focusing a Bessel beam propagating through a flat multi-level diffr…
