A digital hologram-based encryption and compression method for 3D models

Frontiers in Physics, 2022
This study proposes a novel method to compress and decompress the 3D models for safe transmission and storage. The 3D models are first extracted to become 3D point clouds, which would be classified by the K-means algorithm.
