How much accuracy can you possibly get from a 600x600 image?

If you know the flight and the date and time you can easily pinpoint exactly where the plane was and where it was heading. Not incredibly challenging at that point to narrow in on roughly where the photos were taken from.

Well we already know it roughly, it's Indira Gandhi International Airport in New Delhi.

Given that drone warfare is now a thing this seems like it could be useful as the basis of a personal drone detection and warning kit that soldiers could wear over their helmet to spot drones and give say an audible warning in the soldiers ears that lets the soldier locate the drone direction and maybe azimuth with pitch - lower frequency for a low drone and high for one more overhead. Not sure if such a thing already exists. That and a shotgun would be a reasonable defense.

Watching football this fall, I've been thinking about a little box that sits on my table and mutes the TV whenever an ad comes on.

Not decoding HDMI HDCP or anything, but a webcam + AI or whatever that watches football with me and mutes ads. Similar to plane detection, maybe. Are there any projects like this?

I'm kind of surprised that they would park it next to other planes like that. Especially with what appears to be no ground troops surrounding the plane.

>I'm kind of surprised that they would park it next to other planes like that The extreme zoom of the camera makes everything look close together. In reality it's probably quite far from most other planes. >Especially with what appears to be no ground troops surrounding the plane. Why would you have them stand outside to guard the plane when the airport is already fenced off, and has surveillance/security? Even if th…

Guards sitting comfy in an SUV is not a really good guard detail.

Surveillance cameras placed by the airport provides much better situational awareness than a bunch of bored guards standing around.

I'd settle for a device that just normalized the volume levels, but this would be even better!

>If you know the flight and the date and time you can easily pinpoint exactly where the plane was and where it was heading. You'd still need reference data from the photo to triangulate where it was taken from. A blurry 600x600 photo is going to have plenty of uncertainty. >Not incredibly challenging at that point to narrow in on roughly where the photos were taken from. Most people probably don't care as long as it…

I'm under the impression that the OSINT crowd routinely comes to more impressive conclusions based on worse source material.

Nice idea!

In Black Mirror, they pause the advertisement when you disable the sound.

So maybe you'll eventually have to use a separate sound system whereby they cannot detect that you're muting it.

Then, they'll track your eyes and require you to watch the screen :)

At which point do you stop consuming?

Why not, HDCP is only a compliance scheme.
