Closed-circuit TV camera's and video systems are deployed in public places such as the airport, train and bus stations for security purposes. The authorized personnel then go through the generated footage manually to identify possible threats. To partially automate the process, researchers at the University of Granada, Spain have developed a system that can recognize and notify the use of guns in a video.

'Artificially Intelligent' system can recognize guns in videos

The method appears to be yet another application of object recognition technology, which has been around for quite some time now. Taking it a step further, the artificial intelligence built in this system makes sure it learns from its behavior and improve itself over time.

The sampling rate of the system is five frames per second - as good as analyzing the video footage in real time. Whenever the system recognizes a gun, it produces an alert sound along with surrounding the weapon with a red box on the screen. When tested on low-quality videos of movies such as Mission Impossible, James Bond, and Pulp Fiction, the system was accurate around 96 percent of the time!

Social media sites like Facebook, Twitter, and YouTube can make use of this system to prevent violent content on their portals. There is always a glimmer of hope, and technology can turn it into reality.

Watch the system in action in the video below. If you do not understand Spanish, enable and convert the subtitles in a language of your choosing.

Huawei has today launched their latest smartphone under the Honor brand, the Huawei Honor 8 Pro, at an event held in Delhi, India. It had already been announced in Europe earlier this year. The Chinese know the same model as Honor V9. Given its name, it appears to be an upgrade to the Honor 8 which was launched in India last year. Recently, a 'lighter' version, termed the Honor 8 Lite, was also launched.

After the embarrassing battery overheating-and-exploding fiasco, Samsung had to recall all the Galaxy Note 7 units it had sold. Now, a refurbished version of the device is put back on sale in South Korea.

Refurbished Samsung Galaxy Note 7 goes back on sale as Fan Edition

Termed the Galaxy Note 7 Fan Edition, unused components and unopened, recalled units are used to build the new model. The battery capacity is reduced to 3,200 mAh (from 3,500 mAh). It has also been put through the eight-point test to ensure safety.

If you liked what Samsung had to offer via Bixby, their in-house smart assistant, you might turn out to be a 'fan' of the Galaxy Note 7 Fan Edition.

The rest of the specifications are kept as they were - a 5.7-inch Quad HD display (2560x1440 pixels), 4 GB RAM, 64 GB internal memory, and 12 MP primary camera along with 5 MP secondary lens setup. Iris scanning and S Pen are also retained.

Samsung Galaxy Note 7 Fan Edition is priced at 699,600 ($610 approx.), which is around 30% less than the original model's launch price.  Only 400,000 units will be produced. The smartphone comes in black, blue, gold, and silver color options.

The device goes on sale in South Korea on July 7. The company has decided not to launch it in the United States and India, while a call for other markets will be taken at a later date. This could be because the iterative upgrade to the Note lineup, the Galaxy Note 8, is expected to launch by the end of September this year.

Most of us know Toyota as a car manufacturer. What we may not know that they are also into robotics and automation. In 2005, the Japanese multinational announced a project called "Partner Robot." It was the beginning of the switch from industrial robots (which they were making since the 1970s) to household machines. Recently, they have reached a significant milestone in the project with a successful in-home trial of HSR (Human Support Robot) in a war veteran's home in North America. The bot helps people with disabilities carry out their day-to-day activities independently. It was first introduced in 2012.

A tablet interface is provided to interact with HSR. It can be commanded to open doors and fetch water bottles.

The in-home trial is done with Romulo Camargo aka Romy. He is a decorated US war veteran. He was posted in Afghanistan and is paralyzed from the neck down.

"When they opened the box, and I saw the robot, I figured we would unfold the next chapter in human support robots helping people with disabilities – like this research is going to change the world," says Romy.

The next in line for Samsung's most premium Note phones is the much awaited Samsung Galaxy Note 8 which is set to release towards the end of September.

Samsung Galaxy Note 8

According to the latest reports from VentureBeat, the Note 8 might be their priciest phone yet at around €1,000 ($1,119/₹72,000 approx.).

The Samsung Galaxy Note 8 is said to come with a 6.3-inch AMOLED edge-to-edge infinity display, slightly bigger than its Galaxy S8 Plus counterpart making the split-screen operation much easier to use. It will also feature the same aspect ratio of 18.5:9.

The Note 8 will be the South Korean tech firm's first smartphone with a dual camera at the back. It is said to feature two 12-megapixel sensors with independent Optical Image Stabilization for each lens!

It will continue to utilize the same Exynos 8895 or the Qualcomm Snapdragon 835 chipsets - depending on the market, the same ones as the S8 and S8+. Although, this time, the Note 8 will come with a hefty 6 GB of RAM, making it only the second phone from Samsung to feature this much amount of RAM after the Galaxy C9 Pro.

It will sport a small 3,300 mAh battery as opposed to last year's 3,500 mAh battery, most likely to avoid any repeat of the Note 7 battery exploding fiasco. Since then, Samsung has slowly been recovering its reputation and reassuring their users that their phones are safe by implementing an eight-point battery test!

As always, the Note 8 will come with an all-improved S-pen stylus which is said to come packed with more features than its siblings. It can also pin handwritten notes onto the Always-on display.

Also, the Samsung DeX support is said to be included as well which brings desktop-like appearance to the phone! The Note 8 is said to come in shades of blue, black, and gold.
