Modern papers suggest that using a "multi-scale structural similarity index" (MS-SSIM) helps the AI understand the geometry better, leading to "perfect" visual corrections in 3D models.
Researchers often use 3D Convolutional Neural Networks (CNNs), like the U-Net architecture, to "paint over" or remove these ring-shaped defects in 3D scans. [3D] Tamaki (Ring) – NekoPoi
A "papercraft" or physical 3D ring model made of high-quality "deep" paper stock. Modern papers suggest that using a "multi-scale structural
