Hopefully we'll come to a point soon where AI and deep learning can help out in this space. I remember models being trained that could predict the country based on a street view photo with a high degree of accuracy, which would be a good first step. The next one would be to either match a top-down satellite photo with a picture, or figure out a way to match street view photos based on similarity. Given that Google ac…

Maybew Europol could do a Kaggle competition?

That’s not really how any of this works—you can’t simply throw a bunch of unrelated data at some algorithms and expect usable output. (There’s also no such thing as “deep learning”.)

Law enforcement and related organizations already use machine learning quite a bit, particularly for image enhancement. Yes, Google does have a lot of images of various locations from a top-down perspective, but that isn’t helpful for accurately determining a location from the images that Europol collects.

Also, keep in mind that Europol is only posting images here when all other means of determining location and identity have been exhausted. The images are usually indoors and don’t contain enough information for ML to be of any significant use. You might be able to narrow it down to a probably country based colors and design patterns, but that’s hardly sufficient and not solid enough evidence to actually do anything.

Photo number 9. The box shows a picture of an Asteraceae that fits well with Cichorium intybus, a vegetable cultured in temperate areas (from Europe mainly), and the colours of the Romanian flag.

over the green square, appears a whitish blur that could easily say Cicoarea in a stylised way (or maybe is just another picture)

Earlier quoted context omitted.

https://www.europol.europa.eu/sites/default/files/styles/eur... That card looks like a pokemon card with a Google Chrome logo. Frustratingly familiar.

The thing on the back looks surprisingly similar to a package of "Yerba Rosamonte"[1], which would place this picture in Argentina/Uruguay. But it's too low res to say whether that's the case, or just pareidolia. [1] https://www.google.com/search?tbm=isch&q=yerba%20rosamonte&t...

I thought exactly the same.

What do you mean by that?

I wonder if people who use a popular photo sharing site like Google Photos would be in favor of there photos with location meta data being used for a project like this.

I think I would if I could trust that it was only being used for something like this & not commercial advertising type projects.

In this photo there is a small tree at rigth that is partially clipped. Compound leaves with five leaflets. Probably Fraxinus. Fits well. Temperate area in this case.

If is Fraxinus excelsior (probably) Europe. If Fraxinus pensylvannica: Eastern half of USA or Argentina.

Some of the techniques a group on 4chan used are interesting: https://www.ign.com/boards/threads/remember-when-4chan-users...

Remember when 4chan weaponized agains Shia LeBouf's flag and were able to determine the location of the ground flag based on the contrail evidence of the flight path of what the camera could see. The camera was only pointing at the sky, with the flag in the image. They were able to determine approx latitude due to the live stream revealing the sunset - and then comparing the paths of planes seen in the camera with flight data...

Then they drove to the location and took out the flag

Bellingcat does this and more - they also teach a course on it

they triangulated the location of the ISIS execution videos using nothing more than shadows and geographical mounds in the desert
