Wow, where does it stop, then? Can we upsample modern 4k films? Or deeper dynamic ranges? Stereo projections from mono images?

I suppose that the limiting factor is the resolution/color depth/perspective channels of the training images?

It will stop when you hand a computer a novel and a cast as well as the style of your favorite director and then it will produce the film. Think of it as the ultimate in video compression.

Considering how hard it is to pick something to watch on Netflix, I think it will stop when the computer pre-empts what you want to see - 100 channels of interesting generated content!

And there still won't be anything on TV!

> 100 channels of interesting generated content

If I have to choose a channel, or even choose whether to turn the TV on or off, there's still room for improvement.

How do these sorts of techniques perform with respect to temporal coherence?

Since this would probably be more like it is inferring the signal by correlating movies that have similar elements you would need an dataset of 8k signals / dynamic ranges / stereo projections and then you can attempt to perform the up sampling. You were right in your last statement.

I don't see why you'd need a dataset of 8k images in order to upsample 4k to 8k, as long as there are 4k images of that object from at least twice as close as you're shooting from.

(Actually I think twice as close might be 16k, but you get the point...)

4k refers to the number of lines, so twice as close is 8k.
