ULTRAFAST 3D RECONSTRUCTION FROM A SINGLE IMAGE

Summary from the TLDR AI newsletter

Gaussian Splatting has pushed 3D reconstruction forward. However, it often requires 200+ images of an object for accurate reconstruction. This work moves to a single monocular image and a learning-based technique that maps each pixel of the image into a 3d gaussian. The cool novel piece here is the introduction of the “Splatter Image,” which encodes 3D information for downstream rendering.
