Real life CSI: Google's new AI system unscrambles pixelated faces | Technology | The Gu... - 0 views

  •  
    "Google's neural networks have achieved the dream of CSI viewers everywhere: the company has revealed a new AI system capable of "enhancing" an eight-pixel square image, increasing the resolution 16-fold and effectively restoring lost data. The neural network could be used to increase the resolution of blurred or pixelated faces, in a way previously thought impossible; a similar system was demonstrated for enhancing images of bedrooms, again creating a 32x32 pixel image from an 8x8 one."

How funky tortoiseshell glasses can beat facial recognition | Technology | The Guardian - 1 views

  •  
    "Where the researchers struck gold was by realising that a large (but not overly large pair of glasses) could act to "change the pixels" even in a real photo. By picking a pair of "geek" frames, with relatively large rims, the researchers were able to obscure about 6.5% of the pixels in any given facial picture. Printing a pattern over those frames then had the effect of manipulating the image."

MIT's 'PhotoGuard' protects your images from malicious AI edits | Engadget - 0 views

  •  
    "PhotoGuard works by altering select pixels in an image such that they will disrupt an AI's ability to understand what the image is. Those "perturbations," as the research team refers to them, are invisible to the human eye but easily readable by machines. The "encoder" attack method of introducing these artifacts targets the algorithmic model's latent representation of the target image - the complex mathematics that describes the position and color of every pixel in an image - essentially preventing the AI from understanding what it is looking at."

Google Pixel's face-altering photo tool sparks AI manipulation debate - BBC News - 0 views

  •  
    "The camera never lies. Except, of course, it does - and seemingly more often with each passing day. In the age of the smartphone, digital edits on the fly to improve photos have become commonplace, from boosting colours to tweaking light levels. Now, a new breed of smartphone tools powered by artificial intelligence (AI) are adding to the debate about what it means to photograph reality. Google's latest smartphones released last week, the Pixel 8 and Pixel 8 Pro, go a step further than devices from other companies. They are using AI to help alter people's expressions in photographs. It's an experience we've all had: one person in a group shot looks away from the camera or fails to smile. Google's phones can now look through your photos to mix and match from past expressions, using machine learning to put a smile from a different photo of them into the picture. Google calls it Best Take. "

    "The criminals were able to send banner ads and javascript to their targets' computers by pushing both into ad networks. These networks aggressively scan advertisers' javascript for suspicious code, so the criminals needed to sneak their bad code past these checks."

Jaw-dropping Andromeda galaxy photo comprises 37 hours of exposure - CNET - 1 views

  •  
    " Space telescopes such as the Hubble and the Spitzer have spent a lot of time photographing it, and we've seen it in many forms: infrared, false-colour composite, even enormously high-resolution at 1.5 billion pixels."

Where everybody knows your face: Woody Harrelson photo used to spot thief | US news | T... - 0 views

  •  
    "Georgetown University's Center on Privacy and Technology highlighted the April 2017 episode in Garbage In, Garbage Out, a report on what it says are flawed practices in law enforcement's use of facial recognition. The report says security footage of the thief was too pixelated and produced no matches while high-quality images of Harrelson returned several possible matches and led to one arrest."

Artists may make AI firms pay a high price for their software's 'creativity' | John Nau... - 0 views

    "ow, legal redress is all very well, but it's usually beyond the resources of working artists. And lawsuits are almost always retrospective, after the damage has been done. It's sometimes better, as in rugby, to "get your retaliation in first". Which is why the most interesting news of the week was that a team of researchers at the University of Chicago have developed a tool to enable artists to fight back against permissionless appropriation of their work by corporations. Appropriately, it's called Nightshade and it "lets artists add invisible changes to the pixels in their art before they upload it online so that if it's scraped into an AI training set, it can cause the resulting model to break in chaotic and unpredictable ways" - dogs become cats, cars become cows, and who knows what else? (Boris Johnson becoming piglet, with added grease perhaps?) It's a new kind of magic. And the good news is that corporations might find it black. Or even deadly."

Pearson is Now Spying on Students During Standardized Testing ⋆ Ink, Bits, & ... - 0 views

  •  
    "Luckily for the kid, it was only a single tweet. Had several students gotten together to form a study group, they might have been prosecuted for felony interference with a business model and gotten the death penalty. Do you suppose Pearson has hidden microphones set up around the schools so they can also listen in and see if students discuss the tests during lunch? I ask because that is basically the offline version of the student's infraction."
