Was there really the need for AI here? Geo locate the photo shoot, timestamp it and search for a camera that matches? And then it looks like some simple object classifier boxes from open cv to jazz up the images?

I think the bigger issue, one that is valuable is the discussion about privacy in public space. Or a better way to put it, you have no privacy at all in public spaces.

Yeah, there's no need for "AI" software on this project. From the images, it looks like a straight out-of-the-box use of YOLO v7 or something to make it seem more fancy, but this could be easily be done manually without any machine learning at all (or code for that matter).

Hmm, yea privacy in public is an interesting thought. I don’t think its ridiculous to say you should have _some_ privacy, even in a public space. It feels like the expectation is that you can be physically seen, but beyond that I don’t see how someone loses all facets of privacy, unless you’re assuming a surveillance-state.

For the longest time in urban public spaces, there was a sort of privacy by means of the anonymity processed. You knew that you would never see any of the people around you. That's definitely completely gone now.

This adds less than you'd think since people are already tracked by their cellular location. Some off-shoot use cases for this are determining where someone travels and when along with who they interact with by looking at adjacent cellular signals.

You can quickly solve where they would be expected to go in their daily life, what route they'll take to get there, who they will interact with along the way, and when they will be doing it.

Combine this with their credit card purchase history and you can also work out what they're going to buy and how long it will take them to eat it.

I (along with many others who are privacy conscious or are just tech luddites) do not carry my cell phone all of the time.

Albeit noisier, utilizing facial recognition for the same purpose has been in use for a number of years now. They're both identification mechanisms but tracking IMSIs and Mac Addresses gives both better recall and precision than a network of cameras.

You do still legally have an expectation of privacy if you’re having a conversation and at least trying to ensure it’s somewhat confidential.

You don't know when the image was taken, you need to go through the footage until you find the influencer.

May be this wouldn't be that hard to do manually, but making it with an AI shows that it can be don at scale; whether the author here did it or fake I don't know, but the message wouldn't be the same without the AI part.

How do you geolocate a photo shoot and search for a camera that matches? I really don't know what you meant. Assuming you're not talking about phone metadata, of course.
Re:Artist matches influencer photos with surveillance footage by roywiggins on Saturday September 24, 2022 @12:32PM (#32964190)
People geotag their own Instagram posts, you can just search Instagram for photos in Times Square and get loads.

If you only want to do this for a few photos, you just need to (eg) record the Times Square webcams for a couple weeks, then find a couple of recently tagged Times Square photos, make a good guess as to time-of-day and exact photo spot and scrub through your recorded footage from those times until you see someone in those clothes with that pose. It'll take a little while, but with this project you only need to do it a few times.

Keep in mind that the person doing this has all the context from the Instagram account's other photos and captions. Perhaps the same Instagram account made it really obvious what day this trip was happening, which would narrow it down enormously. We don't have that context, but the artist putting this project together has a free choice of which photos to investigate, and in Times Square or in front of Wrigley Field you can surely find some Instagram posts where it's obvious from the surrounding context what day and time it was taken, EXIF data aside.

And that's assuming the artist didn't just hire these people to show up at Times Square at a convenient time for him to press "record" on the webcam.

Re:Artist matches influencer photos with surveillance footage by GenerocUsername on Saturday September 24, 2022 @12:23PM (#32964115)
It's phone geo data.

Not sure if Instagram makes the exif data available

Re:Artist matches influencer photos with surveillance footage by Tostino on Saturday September 24, 2022 @12:28PM (#32964154)
No, exif data is wiped from photos by any of the large social media companies and public photo hosts and has been like that for years.

Edited to add comma.

Re:Artist matches influencer photos with surveillance footage by danso on Saturday September 24, 2022 @01:04PM (#32964520)
I think you’re missing a critical comma?

”No, exif data…”

Re:Artist matches influencer photos with surveillance footage by Tostino on Saturday September 24, 2022 @01:10PM (#32964570)
I think you'd be right!
Re:Artist matches influencer photos with surveillance footage by Dma54rhs on Saturday September 24, 2022 @01:14PM (#32964604)
Instagram strips it but people themselves add the location on their own, that you can maybe access through api or at least minimum by scraping.

Last I heard, Instagram strips EXIF data on upload.

> you have no privacy at all in public spaces.

Have we ever?

Re:Artist matches influencer photos with surveillance footage by cj on Saturday September 24, 2022 @01:24PM (#32964717)
To varying degrees, depending on your definition of privacy.

For example, it used to be possible to go to a public park with a < 5% chance of being in the background of some random photograph taken by a stranger (or 0% depending on how far we go back in history).

Now in many places you can barely walk 1 block without being in the background of someone's iPhone selfie or captured on someone's Ring camera.

Re:Artist matches influencer photos with surveillance footage by alistairSH on Saturday September 24, 2022 @01:22PM (#32964703)
Nope. Only through obscurity - it used to be difficult/expensive to track somebody’s daily movements. Now it’s relatively trivial to do so.
Re:Artist matches influencer photos with surveillance footage by 2OEH8eoCRo0 on Saturday September 24, 2022 @01:53PM (#32965023)
This is where I have trouble. It obviously feels wrong to do at scale in an automated way but the only difference is that it got easier.
Re:Artist matches influencer photos with surveillance footage by alistairSH on Saturday September 24, 2022 @02:34PM (#32965414)
Yeah. I feel the same way. And I realize I facilitate it with my phone and other devices. But still, feels creepy at best and dangerous at worst.
