Drone drops a raft with a beacon on it. Consider it a rescue probe. The beacon attached to the raft has a big button, with some wording or graphic that makes it obvious to "turn knob and push for rescue!". Or maybe it's some floating containerized inflatable raft that needs to be opened in order to be used, and that process triggers the beacon. So if you have a positive hit, it's because the survivor activated the radio beacon and strobe light. A negative hit may still have a lower priority beacon so it would still be possible to recover a rescue package, but it wouldn't be the first one the helicopter would be dispatched to home in on if a positive hit is amongst the released rescue probes.
That way you can have your multiple drones canvassing an area, and have a higher allowance for false positives. That's because you've included a mechanism to verify the good positives, provided your drones find a living and conscious survivor.

Seems like a fleet of drones operating from a ship would be one way of dealing with the Somali pirate problem. Drones are cheap enough to operate that 24/7 high altitude surveillance of the pirate coast is possible, with other surveillance drones dispatched as needed to track any potential pirate boats. Armed drones could intercept a possible pirate boat that was approaching another vessel, and could sink the damn thing if it began to fire on its victim.
The drone pilots could be hired at cheap wages and trained at low cost-- there are more than enough kids out there who would jump at getting paid for their flight simulator skills. An obsolete air craft carrier could handle enough drones to patrol all of NE Africa and SW Asia. One ship with perhaps 100 drones in the air 24/7, a couple hundred spares in the hold, 300 civilian contractor flitesym "pilots" working 8 hour shifts, a dozen Air Force specialists to fly the only drones that carry ordinance, Command/Control personnel, and mechanics and support personnel.

Search and rescue just makes it sound all nice, but the real application is in border protection, replacing expensive aircraft with cheap drones which can be in the air constantly and can cover a much larger area (check a map, overlay on Europe, its an enormous area). Helicopters aren't really used, dont have the range until a navy ship gets close.

Australia is surrounded on all sides by coast, and it spends a ridiculous amount of money on SAR. The COSPAS/SARSAT data makes it clear that distress signals are remarkably common in Australian waters, and though they don't show causes, I'd suspect that culturally people operating in that area have come to assume they will be rescued, much as they too often do in the UK, except the UK is a lot smaller.
Unless these "rotting old boats" have distress beacons and repeatedly trick SAR into thinking they're cargo vessels, fishing vessels, pleasure craft and various other ordinary seeming targets, the COSPAS/SARSAT data suggests that your problem isn't immigrants, it's your natives (or since that's also a pejorative term in Australia, your citizens, that is, you) being incompetent. You have way too many distress incidents, and causes like "out of fuel", "lost" and "fire" generally indicate poorly managed vessels. Take more people's licenses away, or if you don't issue licenses, start.

A person just does not last very long in 40 degree water.

I'd be surprised if in the next 20 years it doesn't become common for a cruise ship to have one or two of these just in case.

A good immersion suit can keep you alive for several hours, at least. There are documented survival times of over 24 hours at around 40 degrees F.

Cruise ships are more likely to have UAVs designed to watch for terrorist / pirate activity rather than purely personnel rescue. I've heard of (but not seen) this being actively researched. Having a humanitarian aspect might make them more palatable.

They can scan full motion video, in real time, looking for objects that are made up of a highly contrasting color? Isn't this just an HSV partitioning? My iPhone can do that in real time (actually, it's a 3G, so it can't do anything at all, thanks for the upgrades Steve).

Use both. The big problem on sea rescue is you have a lot, really a lot of sea to survey. So, the more eyes you have - human or electronic - for the work, better.

I honestly thought this was going to be an article about military technology, since a (pathetic or humorous, take your pick) segment of insurgents seem to believe that wearing a "life jacket" is somehow protecting them from being shot.

It's already possible. A company makes an elongated RC blimp called the Hyperblimp that has already demonstrated solar-powered flight. These things are quite agile and have a decent payload - I think 6lbs has been done on the 30ft model, although I don't know what the solar panels themselves weigh.

Oh sure, the drone can spot you, call for help, and loiter around as long as it can to reassure you that, yes, someone is coming. I bet the drone could even have some supplies attached to a hard point, maybe a capsule with a life raft and five man-days worth of supplies suitable to the area.

Hell, I bet the drone could even act as a WiFi hotspot or wireless repeater. You wouldn't get pulled out of the water right away, but you could sure as hell post all about it on Facebook.

So then the USCG will just snatch you, strap you and your phone to an UAV, and fly you out over the sea/ocean.

Get a grip on what? The plain fact of the matter is that the capability described by TFA is one that has been around since the beginning of computer vision research and is not worthy of the awe, wonder, and excitement espoused in other responses. It is a simple algorithm, and can run quickly on commodity hardware, but I guess since it says "UAV" in the title, everyone wants to salivate and clap and otherwise act like fools over old table scraps. THERE'S NOTHING NEW HERE /.!

The average life jacket doesn't include a good immersion suit. Particularly the ones that they demo every time you take off in an aircraft. (disregarding the other perils of being in an aircraft that just landed in an unexpected place/attitude.)
