A "papercraft" or physical 3D ring model made of high-quality "deep" paper stock.
A specific "Deep" rendering style or texture applied to a 3D character like Tamaki. [3D] Tamaki (Ring) – NekoPoi
Which of these interpretations were you looking for, or were you referring to something else entirely? A "papercraft" or physical 3D ring model made
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. like the U-Net architecture
Inpainting of Ring Artifacts on Microtomographic Images by 3D CNN
In the field of 3D imaging and computer vision, "Ring Artifacts" are common errors that researchers use to fix.
A technical or academic paper about "Deep Learning" or "3D Ring Artifacts" in imaging (e.g., this study on 3D CNNs ).
