Drone images accumulate much faster than they can be analyzed. Researchers have developed a new approach that combines crowdsourcing and machine learning to speed up the process. Who would win in a real-life game of "Where's Waldo," humans or computers? A recent study suggests that when speed and accuracy are critical, an approach combing both human and machine intelligence would take the prize. With drones being used to monitor everything natural disaster sites, pollution, or wildlife populations, analyzing drone images in real-time has become a critically important big data challenge. Publishing in the journal Big Data, researchers, including Stéphane Joost from EPFL, present a new approach to rapidly interpret aerial images taken by camera drones that combines human crowdsourcing and machine learning.

Every time we post about autonomous delivery drones, we have to point out that despite the promises implied by overproduced and optimistic videos, the drones are simply not capable of autonomous navigation in complex environments. Same goes for those camera drones that promise to follow you: the videos inevitably show them following skiers on wide open slopes, surfers on the wide open sea, or other people doing things very far away from inconvenient obstacles like trees. So far, we've only seen a tiny handful of drones capable of dynamically detecting and avoiding obstacles at a useful speed. Qualcomm and UPenn have been working on some, and MIT has that speedy tree-avoiding fixed-wing drone. A Silicon Valley company called Skydio, founded by a team of researchers from MIT and Google X's Project Wing, have posted a video that shows a drone following people jogging and biking while autonomously avoiding tree trunks and branches.

An anti-tank missile fires by an Iraqi CH-4 drone destroys an ISIS artillery piece, seen in footage captured by the drone's onboard, retractable sensor turret. China's armed CH-3 and CH-4 drones have recently made international news, being used by nations that range from Iraq to Nigeria. And now NORINCO, one of China's leading defense contractors, is getting in on the international drone export game, showing off a new armed drone helicopter. The Sky Saker H300, seen here in Dubai, is China's first helicopter UCAV. Being cheaper and easier to use then larger UCAVs like the Reaper and CH-4, it could become a battalion and company level UCAV for on demand air strikes.

A near miss between a drone and a Lufthansa aircraft landing at Los Angeles International Airport may give impetus to moves to regulate consumer drones more closely, including by using technologies like geofencing. "This is one more incident that could have brought down an airliner, and it's completely unacceptable. A near-miss of 200 feet should serve as a stark reminder of the dangers posed by reckless drone use," said Senator Dianne Feinstein, a Democrat from California, in a statement. The senator said the Senate must pass legislation she introduced last year, called the Consumer Drone Safety Act, which would require safety features for consumer drones and strengthen the federal laws that govern their operation. The bill would, among other things, direct the Federal Aviation Administration to require safety features for newly manufactured consumer drones, such as geofencing to govern the altitude and location of flights and collision-avoidance software.

Say what you will about civilian drones and drone pilots, but when the going gets tough, these drone pilots will get going. According to published Federal Aviation Administration (FAA) commercial drone exemption requests, a big chunk of drone pilots are willing to lend a hand for possible emergencies. A total of 19 percent mentioned emergency services--that's six times as many requests from the last quarter of 2015. With all these pilots willingly to help out in case of emergencies, this could mean that private pilots can easily aid officials during search and rescue missions and other equally critical emergency scenarios. Despite this magnanimous offer to lend a hand, it doesn't necessarily guarantee pilots flying time. Certain legal restrictions may keep them on the ground– according to an FAA spokeswoman who spoke to The Verge, "a civilian must have a 333 exemption" to participate in emergency services.

The Diet on Thursday enacted a law banning drones from flying over important facilities such as the Prime Minister's Office while giving police the power to destroy drones if necessary. The legislation is expected to take effect before a foreign ministerial meeting of the Group of Seven industrial nations takes place in Hiroshima on April 11-12. Prime Minister Shinzo Abe's ruling coalition had been seeking early enactment of the bill to strengthen anti-terrorism measures ahead of the G-7 summit in Mie Prefecture in late May. The Civil Aeronautics Law was revised to regulate drone flights in September after a small drone was found on the roof of the building housing the Prime Minister's Office last April. A man was later convicted over the incident.

The pilot of a Lufthansa passenger jumbo jet has reported that a drone aircraft nearly collided with his airliner on its landing approach to Los Angeles, according to the Federal Aviation Administration. The close encounter between the wide-body, four-engine Airbus A380 and the drone occurred at about 1.30pm at an altitude of 5,000ft (152 metres) as the unmanned aircraft passed about 200ft (61 meters) over the Lufthansa flight 14 miles (22.5 km) east of the city's international airport, the FAA said. No evasive action was taken by the airline crew, and the plane, Lufthansa Flight 456, safely made its landing minutes later without further incident, according to FAA spokesman Ian Gregor. The FAA immediately alerted the Los Angeles police department's air support division. The number of passengers and crew aboard the plane was not reported by authorities, nor was the flight's origin.

JUDY WOODRUFF: A movie thriller being released nationally today delves into the practical, legal and moral issues surrounding drone warfare. HELEN MIRREN, Actress: We need to put a Hellfire through that roof right now. JEFFREY BROWN: It's a new kind of warfare, advanced technology that tracks, identifies, and has the power to destroy enemies by remote control from thousands of miles away. HELEN MIRREN: We have two suicide vests with explosives inside that house. JEFFREY BROWN: But as the film "Eye in the Sky" asks, should it be used?

It wouldn't be CES without a new drone from Parrot. Not that we're complaining: Parrot makes awesome drones. You can probably guess what's new about the Disco, though: a pronounced lack of rotors and the addition of a symmetrical pair of passive lifting surfaces. In other words, it's got wings. As soon as we saw this thing, we were like, "Oh, that looks familiar!"

Last week was a holiday, and we're at CES this week, but nothing can stop the robot videos. Things should be back to normal around here next week (we hope). Let us know if you have videos or events to suggest, and enjoy today's Video Friday selection! Teaching robots how to avoid destruction and despise humanity at the same time is never a good idea. The world's most advanced bat robot now has membrane wings, just like real bats: A microprocessor-based onboard computer, a 6 DOF IMU sensor package, five DC motors with encoder feedback for flapping and wing articulation (asymmetric wing folding and leg/tail control), power/comm electronics, carbon-fiber frame, 3D printed parts, and silicone based membrane wings -- all at 92 grams.
