Combining multiple CCTV images could help catch suspects
Combining multiple poor quality CCTV images into a single, computer-enhanced composite could improve the accuracy of facial recognition systems used to identify criminal suspects, new research suggests. Psychologists from the universities of Lincoln and York, both in the UK, and the University of New South Wales in Australia created a series of pictures using a ‘face averaging’ technique – a method which digitally combines multiple images into a single enhanced image, removing variants such as head angles or lighting so that only features that indicate the identity of the person remain. They compared how effectively humans and computer facial recognition systems could identify people from high quality images, pixelated images, and face averages. The results showed that both people and computer systems were better at identifying a face when viewing an average image that combined multiple pixelated images, compared to the original poor-quality images. Computer systems benefited from averaging together multiple images that were already high in quality, and in some cases reached 100 per cent accurate face recognition.
The results have implications for law enforcement and security agencies, where low quality, pixelated images are often the only pictures of suspects available to use in investigations. The image averaging method offers a standardised way of using images captured from multiple CCTV cameras to create a digital snapshot which can be better recognised by both people and computer software systems. We have shown that there is a relatively quick and easy way to improve pixelated images of someone’s face. In the study, participants were asked to compare a high quality image with either a low quality pixelated image or one created using the image averaging method, and determine whether they depicted the same person or two different people. Results showed that accuracy was significantly higher when viewing an average combining pixelated images, rather than a single pixelated image.
The same test images were run through two separate computer recognition programmes, one a smart phone application, and the other a commercial facial recognition system widely used in forensic settings. Both computerised systems showed higher levels of accuracy in identifying a person from average images.
Saudi journalist killing: CCTV gives clues in Jamal Khashoggi ‘slaying’
His name is Maher Abdulaziz Mutreb, a Saudi intelligence officer and former diplomat, who has now been seen in a number of leaked CCTV images, which Turkish media claims are suspicious. The images, published in the Turkey’s Sabah newspaper overnight, shows his movements near the Saudi Arabian consulate in Istanbul two weeks ago, when Jamal Khashoggi disappeared. Turkish officials believe the alleged hit squad travelled back to the Saudi capital of Riyadh in two private jets that evening. Asked about the potential US response to Saudi Arabia, which is accused of murdering the Washington Post. GORY DETAILS.
Neither Turkey nor the United States has publicly confirmed that Jamal Khashoggi is dead or said officially that Riyadh is to blame. A steady stream of unconfirmed leaks from officials to Turkish media have painted a detailed and horrifying picture of Khashoggi’s last minutes, allegedly at the hands of 15 Saudi agents waiting for him when he came to the consulate for paperwork. Meshal Saad M Albostani, a lieutenant in the Saudi Royal Air Force, is said to have been killed in a car accident in Riyadh. He is among a group of men wanted for questioning after Khashoggi went missing having entered the Saudi Arabian consulate in Istanbul two weeks ago. Citing what it described as an audio recording of Khashoggi’s slaying, said a Saudi team immediately accosted the 60-year-old journalist after he entered the consulate, cutting off his fingers and later decapitating him.
Mr Mutreb’s name matches that of a first secretary who once served as a diplomat at the Saudi Embassy in London, according to a 2007 list compiled by the British Foreign Office. The same name also appears in an email published by WikiLeaks from the 2015 breach of surveillance company Hacking Team of Saudi officials being trained to use their software. JAMAL KHASHOGGI’S FINAL COLUMN. On Thursday, the Post published what it said was Khashoggi’s last column, in which he pointed to the muted international response to ongoing abuses against journalists by governments in the Middle East.
Ryanair posts CCTV footage showing ‘fake photo’ of sleeping crew
Ryanair has said a photograph purporting to show crew members sleeping on the floor of a staff lounge was staged, and has released CCTV footage to back up the claim. The airline posted the footage which was taken in the crew room of Malaga Airport on Saturday night. It shows seven members of a Ryanair cabin crew lying down on the floor while another member of crew takes photographs of them on a mobile phone. The incident occurred after four Ryanair crews bound for Portugal were diverted to Malaga Airport because of storms in Portugal. Twenty-eight Ryanair employees spent the night in the crew room at the airport as the airline claimed that all hotels in the Malaga region were booked.
Ryanair suggested the footage exposed the SNPVAC, the Portuguese aviation union, which have been to the forefront in highlighting the original photograph. He said nobody involved in the taking of the photograph, which went viral across the internet, ever claimed that it was real. It had been taken, he said, as a protest by Ryanair staff to illustrate the conditions they endured when the airline failed to find hotel rooms for them in Malaga. Mr Gandra said he wanted to thank Ryanair for proving the point they had set out to prove in the first place. The original photograph was posted on a Facebook page Ryanair Must Change and then posted to Twitter by former Ryanair pilot Jim Atkinson.
He hoped the crews will sue Ryanair for the invasion of their privacy, but Ryanair denies that there was any breach of privacy.
