This reminded me of a weird idea that I had several years ago (which is kind of opposite of this):

What if there was a format that doesn't encode pixels but generates a "description" of the images using AI, of simple shapes to higher-level objects, and saves that in its own format, with a "decoder" that takes this input description format and constructs an image similar to the original, at least to some extent.

Of course this would have many drawbacks like encoding micro details and expressions of people, but still, I'd love to see how far the idea can go.

Venor Vinge, A Fire Upon The Deep (1992):

>Fleet Central refused the full video link coming from the Out of Band … Kjet had to settle for a combat link: The screen showed a color image with high resolution. Looking at it carefully, one realized the thing was a poor evocation…. Kjet recognized Owner Limmende and Jan Skrits, her chief of staff, but they looked several years out of style: old video matched with the transmitted animation cues. The actual communication channel was less than four thousand bits per second

>The picture was crisp and clear, but when the figures moved it was with cartoonlike awkwardness. And some of the faces belonged to people Kjet knew had been transferred before the fall of Sjandra Kei. The processors here on the Ølvira were taking the narrowband signal from Fleet Central, fleshing it out with detailed (and out of date) background and evoking the image shown.

This could be useful to reduce Disney’s bandwidth costs. Marvel and Star Wars productions are highly repetitive anyway, so maybe they could ship a preloaded Marvel neural network in the player app and design new movies to take maximum advantage of the clichés already encoded there.

They used to literally reuse the animation in older Disney films, just with different characters on top. You could send that information, the scene and the characters, in significantly fewer bits than it would take as video

Not entirely unlike fractal compression[1]. Was a lot of hype around it way back, but clearly it didn't quite pan out.

that's roughly the idea for gan-based image compression, check out: https://data.vision.ee.ethz.ch/aeirikur/extremecompression

It's called SVG :)

Not really. But vectorized shapes might definitely help rasterizing the descriptions.

that's like heraldry, rebuilding an image from a precise/regimented verbal description

sounds like vector graphics?
Re:Silly Image Compression Idea by can16358p on Monday April 11, 2022 @04:26PM (#30994440)
Nope. But vector graphics can be of great utility when rasterizing the description into a bitmap.
