Hacker News with Generative AI: 3D Reconstruction

3D reconstruction of the capital of the Aztec empire (thomaskole.nl)
The year is 1518. Mexico-Tenochtitlan, once an unassuming settlement in the middle of Lake Texcoco, now a bustling metropolis. It is the capital of an empire ruling over, and receiving tribute from, more than 5 million people. Tenochtitlan is home to 200.000 farmers, artisans, merchants, soldiers, priests and aristocrats.

Self-Occluded Avatar Recovery from a Single Video in the Wild (soar-avatar.github.io)
A Unified Framework Self-occlusion is common when capturing people in the wild, where the performers do not follow predefined motion scripts. This challenges existing monocular human reconstruction systems that assume full body visibility. We introduce Self-Occluded Avatar Recovery (SOAR), a method for complete human reconstruction from partial observations where parts of the body are entirely unobserved. SOAR leverages structural normal prior and generative diffusion prior to address such an ill-posed reconstruction problem.
