Scientists have developed a new 3D facial recognition system that can improve security measures while potentially removing the need for personal passwords. Researchers from The University of Western Australia created the first-of-its-kind model – called FR3DNet – analysing 3.1 million 3D scans of more than 100,000 people.
They trained the model to learn the identities of a large dataset of ‘known’ persons and then match a test face to one of those identities. Facial recognition is fast becoming the tool of choice for surveillance, security and IT industries and relies on the ability of computer models to determine whether or not a person is legitimate. Currently, 2D facial recognition of photographs is widely used and has seemingly surpassed human accuracy levels however it has several shortcomings that the more advanced 3D model is able to address.
Unlike 2D facial recognition software, 3D models have the potential to address changes in facial texture, expression, poses and scale, yet the data is difficult to gather. 2D facial data can be obtained simply by searching the internet while 3D facial data requires physical collection from real subjects thereby limiting its use. The 3D model’s creator Syed Zulqarnain Gilani said the model was a huge step forward in the field of 3D facial recognition.
“With off-the-shelf 3D cameras becoming cheap and affordable, the future for pure 3D face recognition does not seem far away,” Gilani said. “Our research shows that recognition performance on 3D scans is better and more robust. Your 3D scan could be in any pose, wearing glasses or a face mask, and laughing or just smiling and the deep model can recognise you in an instant,” he said. “We hope that this research will help improve security on devices that use facial recognition to grant access to networks and systems,” he added.
Bose Frames AR Audio Sunglasses Launched in India, Priced at Rs. 21,900
Over a year after originally showcasing its audio AR sunglasses, Bose is bringing them to the Indian market. The company on Thursday announced that the sunglasses, which are simply known as Bose Frames, will go on sale beginning next week in the country alongside Bose Frames Lens Collection. The Bose Frames combine three functionalities into one device – premium sunglasses, wireless headphones, and audio AR features. The Bose Frames are the company’s first product to be based on the company’s AR platform.
The Bose Frames carry a price tag of Rs. 21,900 and will be offered in two universal styles – the larger Alto and the smaller Rondo. The Bose Frames Lens Collection of non-polarised and polarised lenses will retail at Rs. 1,990 and Rs. 2,990, respectively. The sales open June 20 via select resellers and Bose stores in the country.
The Bose Frames are essentially a pair of sunglasses that pack a tiny Bose audio system in the temples. This audio system effectively turns them into a wireless pair of headphones. The Bose Frames also include a microphone and multi-function button on the right temple for power and pairing, Siri and Google Assistant, calls and commands, or to pause and skip songs.
“With a proprietary open-ear design, they [Bose Frames] take micro-acoustics, voice control, and personal audio to an entirely new level, so users can stream music and information, take and make calls, and access virtual assistants from — while keeping playlists, entertainment, and conversations private,” Bose said in a statement.
Like many wearable devices, the Bose Frames act as a companion device to your smartphone and need the same for processing the information and connecting to the Web.
As we mentioned earlier, the Bose Frames will be released in two designs – Alto and Rondo. Alto is square and angled, whereas Rondo is round and smaller. Both can block up to 99 percent of UVA/UVB rays and weigh just 45 grams. The lenses can be easily popped out and replaced.
Apart from the audio capabilities, the Frames are also compatible with Bose’s AR platform. The Bose Frames don’t include any visual AR capabilities, but they can provide audio AR input to enhance your experience.
“[Bose Frames] knows where you are and what you’re facing using a 9-axis head motion sensor and the GPS from your iOS or Android device — and automatically adds a layer of audio through Bose AR apps, connecting that place and time to endless possibilities for travel, learning, entertainment, gaming, and more,” Bose explained.
Bose AR apps can be downloaded using Bose Connect app and are only available for iOS right now. Android apps are being developed, according to the company’s website.
The company claims that onboard battery can last up to 3.5 hours for playback and up to 12 hours on standby. It can be fully recharged in less than two hours.
Novel device can quickly detect strokes
Scientists have developed a device that can monitor blood flow and help quickly diagnose and treat strokes.
A stroke, one of the leading causes of death worldwide, occurs due to poor blood flow to the brain — a condition known as cerebral ischemia.
Its diagnosis must be done within the first few hours for treatment to be effective, researchers said.
The hybrid device, developed by researchers at the China Academy of Engineering Physics and Army Medical University in China, relies on a combination of to light measuring techniques which could diagnose cerebral ischemia non-invasively and faster than the techniques used currently.
“We can measure blood volume, blood oxygenation and blood flow using suitable near-infrared techniques,” said Liguo Zhu, from China Academy of Engineering Physics.
Zhu said that “near-infrared light penetrates one to three centimetres and allows researchers to probe under the skin.”
The working of the instrument relies on the combination of the near-infrared diffuse optical spectroscopy, which analyses the light scattered from the tissues to calculate the amount of oxygen and blood within an area, and the diffuse correlation spectroscopy, which analyses fluctuation in the tissue-scattered lights to measure blood flow.
“Both techniques share the same detectors, which decreases the number of detectors compared to other instruments,” said Zhu.
“The team’s device can record a comprehensive profile of a body part’s hemodynamics, or blood circulation. Devices should measure as many ‘hemodynamic parameters’ as necessary to obtain an accurate diagnosis, as ‘the hemodynamics of stroke is complex’,” said Hua Feng, from Army Medical University.
Another advantage of the device is that it is cheap and compact, which would make more accessible to the people, and hence, help treatment, diagnosis and chances of stroke, researchers said.
Parineeti ‘still learning’ to play badminton
Actress Parineeti Chopra has not started shooting for ‘Saina’ yet and says she is still learning how to play badminton.
Parineeti on Thursday said that the shooting for the biopic will commence in October.
“Hi everyone, we have not started the shoot of ‘Saina’ yet. I am still learning how to play Badminton! We will start in October once I get better at it! Four months to go,” she tweeted.
Parineeti had replaced actress Shraddha Kapoor in the Saina Nehwal biopic, which is being directed by Amole Gupte.
She will next be seen in ‘Jabariya Jodi’ along with actor Sidharth Malhotra. The film is scheduled for release on August 2. Directed by Prashant Singh, ‘Jabariya Jodi’ is based on ‘Pakadwa Vivah’ (forced marriage), which was once rampant in Bihar.
