Someone help me out here. They're not making real holograms, and pictures of 3D objects don't require much power. Are they generating but not displaying holograms? Are they generating 3D objects and displaying them in 2D?
I don't see where you got that from. They're generating holograms, and displaying them.
The first holograms were recorded on film then projected by shining a light on the film. Today you can replace the film with a CCD, and for display, with a "spatial light modulator" which is a super expensive LCD.
So what they're doing is taking a synthetic 3D scene, using a convolutional neural network to turn it into a hologram, displaying the hologram on the SLM, shining a light through it, and voila, a projected hologr
TL:DR the guys get the famous royalty-free Big Buck Bunny video source, which is just 2D, extract depth from that source, and create a 3D representation which is effectively a holographic one.
So, holography (and holograms) in the context of the paper is the process of generating 3D representations from 2D sources (in this case 2D sources with depth data or from where depth can be extracted and/or extrapolated). Part of creating a hologram involves that process, because even current 3D scanning involves reco

Same confusion here. Are they saying Deep Learning is powerful enough to turn 2D displays into 3D ones?

Looks like they're generating but not displaying holograms.
