one of cool google projects that does not take off because its so hard to run and integrate with other cool things...

If we take the less cynical take, it'll end up in Youtube as audio description for people with visual impairments.

It'll become a standard option in CCTV and as an extension a tool for overly authoritive bosses.

Had this idea about 5 years ago, seems like it might be viable now, would love to see a video analyzer that creates relationship graphs using sentiment analysis. Ex. who responds to whom, what their tone is, how often. Hopefully with modern methods, it wouldn't take too many examples to pick out the dimensionality of expression (cheating out vs in, loudness + arousal, whining on the spectrum of playful to hurt, confi…

My first thoughts were also how this would effect the porn industry…

> when they create context from unrelated scenes by cutting from one to the other. Do you mean juxtaposition?

Was thinking of https://en.m.wikipedia.org/wiki/Kuleshov_effect.

That's along the same vein tho

It is perfect for Audio Description [1]. Certain broadcast TV programs have had this here in Australia to allow those with poor vision to be able to follow along - it allows them to appreciate content that has originally be produced as audio-visual. https://en.wikipedia.org/wiki/Audio_description?wprov=sfla1

Some of this: https://vi.microsoft.com/en-us

Huh, had no idea that existed. Looks a lot like this project.

But no, that's not it at all. The sentiment analysis buried at the bottom there is generic. It's advertised for aggregate customer mood bc that's the only thing it's sensitive enough to detect, thumbs up or down.

I mean something like https://m.youtube.com/watch?v=8dagzaFjHU4&t=2m, the expressions in the eyes, ex. concern - solicitous - complacent/satisfied - steely from 2:10 - 2:20.

That + the same for voice tone would be everything.

This isn’t really a “google project” in the way I think about that term, but it’s a research project. Google’s research is constantly advancing and when things get far enough along they do tend to get used in production. Individual research papers are just a step along the way. This research seems useful for training video generation systems like transformers and especially multi modal systems. Imagine you have a rob…

I suspect this or something like it has already “taken off”, but only internally at google. They seem to be a lot better at searching the contents of YouTube videos than simple transcripts or image detection would give.

Anyone figured out how to run this against a video?

https://github.com/google-research/scenic/tree/main/scenic/p... has an example showing how to "train Vid2Seq on YouCook2" using "python -m scenic.projects.vid2seq.main", but I couldn't see the recipe for using it against a video to return a description.
