Deep 3D-to-2D Watermarking: Embedding Messages in 3D Meshes and Extracting Them from 2D Renderings. (arXiv:2104.13450v3 [cs.CV] UPDATED)

Digital watermarking is widely used for copyright protection. Traditional 3D
watermarking approaches or commercial software are typically designed to embed
messages into 3D meshes, and later retrieve the messages directly from
distorted/undistorted watermarked 3D meshes. However, in many cases, users only
have access to rendered 2D images instead of 3D meshes. Unfortunately,
retrieving messages from 2D renderings of 3D meshes is still challenging and
underexplored. We introduce a novel end-to-end learning framework to solve this
problem through: 1) an encoder …
