A trio of researchers at Johannes Kepler University has used artificial intelligence to improve thermal imaging camera searches of people lost in the woods. In their paper published in the journal Nature Machine Intelligence, David Schedl, Indrajit Kurmi and Oliver Bimber, describe how they applied a deep learning network to the problem of people lost in the woods and how well it worked.
When people become lost in forests, search and rescue experts use helicopters to fly over the area where they are most likely to be found. In addition to simply scanning the ground below, the researchers use binoculars and thermal imaging cameras. It is hoped that such cameras will highlight differences in body temperature of people on the ground versus their surroundings making them easier to spot. Unfortunately, in some instances thermal imaging does not work as intended because of vegetation covering subsoil or the sun heating the trees to a temperature that is similar to the body temperature of the person that is lost. In this new effort, the researchers sought to overcome these problems by using a deep learning application to improve the images that are made.

I think I’ve seen the other one. One of my faves is when DP went to Australia and spoke at s convention. You could tell the audience did NOT know these disappearances until he stopped 2 hours later, and it took one American to dig up the information.
Yea, cause helicopters cannot be equipped with thermal imaging cameras. Or something.
Drones make sense from the cost perspective. I’d think a search team could deploy several at a time with pre-programmed search patterns.
I also see a drawback. The lost person can hear a helicopter coming and make themselves more noticeable.
For how many of us was that the first thing that popped into our minds.

Ha-ha. Me too.
“Lost in the woods.” Riiigght. F’n hunter-killer drones.
