Police facial recognition camera trial hindered by software setbacks

Daily Mail - Science & tech

A police force's use of facial recognition technology requires'considerable investment' to deliver consistent results, a study has concluded. Crashing computer systems and poor quality images are among the challenges South Wales Police officers have faced since rolling out the technology. Large crowds, low lighting and people wearing glasses were all issues the AI software struggles to cope with, experts found. South Wales Police force first deployed automated facial recognition at the 2017 Champions League final in Cardiff. This led to the technology wrongly matching more than 2,000 people to possible criminals.


A Generic Multi-modal Dynamic Gesture Recognition System using Machine Learning

arXiv.org Machine Learning

Human computer interaction facilitates intelligent communication between humans and computers, in which gesture recognition plays a prominent role. This paper proposes a machine learning system to identify dynamic gestures using tri-axial acceleration data acquired from two public datasets. These datasets, uWave and Sony, were acquired using accelerometers embedded in Wii remotes and smartwatches, respectively. A dynamic gesture signed by the user is characterized by a generic set of features extracted across time and frequency domains. The system was analyzed from an end-user perspective and was modelled to operate in three modes. The modes of operation determine the subsets of data to be used for training and testing the system. From an initial set of seven classifiers, three were chosen to evaluate each dataset across all modes rendering the system towards mode-neutrality and dataset-independence. The proposed system is able to classify gestures performed at varying speeds with minimum preprocessing, making it computationally efficient. Moreover, this system was found to run on a low-cost embedded platform - Raspberry Pi Zero (USD 5), making it economically viable.


Samsung Galaxy S8's facial recognition security feature has already been tricked

The Independent - Tech

A video appearing to show somebody trick the new Samsung Galaxy S8's facial recognition technology has emerged. The handset, which was launched earlier this week, allows users to unlock the phone with their face. It's a fast and convenient alternative to PINs, passcodes and patterns, but might not be the most secure of options. The clip, posted on Twitter by Marcianotech, appears to show a user unlock a Galaxy S8 with a picture of his own face. He doesn't manage it right away, taking several minutes to get the picture into position, but you can see his successful attempt just after the nine-minute mark.


Will makeup trick the iPhone X's facial recognition?

Mashable

The iPhone X's new Face ID facial recognition technology allows users to unlock their phone simply by holding it up to their face. But how does it handle contouring? We hired professional makeup artists to put it to the test.


Is the iPhone X's facial recognition twin compatible?

Mashable

We put Apple's'Face ID' technology to the test with twins. Facebook, friends, and even relatives get these fraternal twins mixed up all the time.
