AI technology is improving at an amazing rate. However, video is still a significant challenge. Wired reported on a development that may improve things, whilst also using less processing power.

A group from MIT and IBM developed an algorithm capable of accurately recognizing actions in videos while consuming a small fraction of the processing power previously required, potentially changing the economics of applying AI to large amounts of video. The method adapts an AI approach used to process still images to give it a crude concept of passing time. The work is a step towards having AI recognize what’s happening in video, perhaps helping to tame the vast amounts now being generated. On YouTube alone, over 500 hours of video were uploaded every minute during May 2019. Companies would like to use AI to automatically generate detailed descriptions of videos, letting users discover clips that haven’t been annotated. And, of course, they would love to sell ads based on what’s happening in a video.

Apple’s much speculated upon self-driving car might have a radar system hidden within the bodywork. That’s according to a patent granted Tuesday and uncovered by AppleInsider.

In Apple’s design, it suggests the use of antennas to transmit a radar beam towards a portion of a field of view, along with a vertical antenna array to receive the bounced-back signal. The receive antenna array can consist of multiple antenna elements grouped into sub-arrays, with each sub-array used to receive scatter signals reflected back at it from a smaller subsection of the field of view. Circuitry is then used to combine the received scatter signals from the antenna array into a combined scatter signal, which is then digitized. A second horizontal receive array performs a similar job, again with sub-arrays and the same process. A signal processor is then used to process the scatter signals from both vertical and horizontal arrays, and to correlate the data from each to give effectively a 3D radar layout.

U.S. elections are big business. Reuters published a fascinating report into how Amazon moved into the world of politics.

Amazon pitches itself as a low-cost provider of secure election technology at a time when local officials and political campaigns are under intense pressure to prevent a repeat of 2016 presidential elections, which saw cyber-attacks on voting systems and election infrastructure. “The fact that we have invested heavily in this area, it helps to attest to the fact that in over 40 states, the Amazon cloud is being trusted to power in some way, some aspect of elections,” Michael Jackson, leader, Public Health & U.S. Elections at AWS, told prospective government clients in February via a presentation on a webinar, which was viewed by Reuters.

Facebook cryptocurrency has lost a number of big-name backers in recent times. Reuters reported on the problems facing Libra, and looked at where the project might go next.

PayPal (PYPL.O) started the Libra Association exodus this month, leaving Facebook without the backing of any major payments firms for the project, due for launch by June 2020. Libra said this month it would give details after the meeting of the 1,500 “entities” that have indicated “enthusiastic interest” to take part in the project. Members will review a charter and appoint a board at the Libra meeting, which will be held in Geneva, the Wall Street Journal reported this month. A spokeswoman did not immediately respond to enquiries on the meeting of the Libra Association, whose remaining members include Vodafone (VOD.L) and ride-hailing firms Uber and Lyft.

I know. You’re only just getting used to your new iPhone 11. But Lisa Eadicicco at Business Insider is already looking at what comes next for Apple.

Among the biggest changes that’s expected to come with Apple’s 2020 iPhones is the introduction of a more sophisticated three-dimensional camera, according to Bloomberg’s Mark Gurman and Debby Wu. Such a camera system would include a laser scanner to create 3D replicas of the real world, boosting the iPhone’s augmented reality capabilities. With the new 3D camera, the iPhone would be better at placing virtual objects in augmented reality and would offer enhanced depth perception, according to Bloomberg. Apple’s iPhones have supported augmented reality applications for years, and the company made its first big push into AR when it launched ARKit in 2016 — a set of tools to help mobile developers build high-quality AR apps.

NASA is aiming for a manned SpaceX mission in the first quarter of 2020. NASA chief Jim Bridenstine made the announcement Thursday, Reuters reported.

The pronouncement of a revised time frame signaled NASA believes SpaceX is getting the Crew Dragon project back on track following an explosion during a ground test in April and technical challenges with its re-entry parachute system. Bridenstine said successful development of the capsule was key to achieving NASA’s top priority – the resumed “launching of American astronauts on American rockets from American soil” for the first time since the space shuttle program ended in 2011. The NASA administrator spoke to reporters at the end of a visit to the SpaceX headquarters in Hawthorne, California, just outside Los Angeles, where chief executive Elon Musk led him on a tour of the sprawling manufacturing plant.
