Koreatech-CGH

This dataset consists of RGBD–complex hologram pairs designed for training machine learning–based computer-generated holography (ML-CGH) models.
It can be used for tasks such as hologram generation, hologram upscaling, and related applications.

The holograms were generated using a layer-based hologram generation method[arxiv].
