Method for providing optimized holograms by extracting system characteristics of holographic display

A hologram providing system comprising:

• a processor configured to:
• extract system characteristics of a holographic display by comparing a first hologram that is generated by a holographic display system from a reference image using a first hologram generation neural network that is trained to learn the system characteristics of the holographic display and a second hologram that is numerically reconstructed from the reference image by an ideal numerical hologram generator of the holographic display system without the system characteristics of the holographic display being reflected thereon;
• and
• provide an optimized hologram generated by a second hologram generation neural network of the holographic display server that is trained to receive image content and the extracted system characteristics as inputs and to generate the optimized hologram specific to the holographic display,
• the second hologram generation neural network being different from the first hologram generation neural network of the holographic display system.

A method for extracting system characteristic of a holographic display, the method comprising:

• receiving, by a hologram providing server, a system parameter of the holographic display from a holographic display system;
• generating, by the hologram providing server, a reference image based on the system parameter of the holographic display, and transferring the reference image to the holographic display system;
• receiving, by the hologram providing server, a first hologram that is generated by the holographic display system from the reference image using a first hologram generation neural network that is trained to learn the system characteristics of the holographic display, and a second hologram that is numerically reconstructed from the reference image by an ideal numerical hologram generator of the holographic display system without the system characteristics of the holographic display being reflected thereon;
• and
• extracting, by the hologram providing server, the system characteristics of the holographic display by comparing the received first hologram with the received second hologram.
