A recent photographic analysis technique developed by Professor Siwei Lyu and his team at the University at Albany – SUNY could lead to better forensic analysis of altered images. The technique takes advantage of the fact that, when splicing two images together, each will bring with it the specific noise pattern of the camera it was shot with.
So, when analyzing the obviously fake image at the top, the flamingo Tiger Woods is using in lieu of his golf club shows up as having a different noise pattern than the rest of the image. Read more…
Former Photoshop product manager Kevin Connor and Dartmouth professor (and digital forensic expert) Hany Farid are working together to help put a stop to image manipulation where it doesn’t belong. Putting their two brains together they formed a company called Fourandsix, which is primed to release a full suite of software tools that will help law enforcement officers, photo editors and other interested parties detect secret digital photo manipulation.

Demos at graphics conferences are often interesting to watch because they offer a sneak peek at technologies that may soon become available to the general public. The video above is a demo for “PatchMatch“, an algorithm developed by researchers at Princeton and Adobe. Although you might be unfamiliar with PatchMatch, you’ve probably heard of its most famous feature: Content Aware Fill. Only a small piece of this amazing technology was introduced in Photoshop CS5, so the amazing image manipulations seen in this demo are likely a sneak peek into what we’ll be seeing in Photoshop CS6.
It’s a big no-no when newspapers or photographers manipulate photos to alter reality, but when a father playfully does it to mess with his kids there’s a big potential for awesome. Graphic designer Anthony Herrera recently did just that, and his story is now making the rounds on the Internet:
A year ago we took a trip to Sequoia National Park. I wanted to excite my daughter while being in such amazing surroundings. Being the Star Wars geek that I am (so is she), I told her that this is where the Ewoks live. She spent a good chunk of our time hiking keeping a lookout for any Ewoks. Coming home I can’t say that she wasn’t disappointed that we didn’t find any. I had to explain that they are extremely shy and hardly ever let anyone see them. After we got home, and after I had a little time alone with the photos, I told her I thought I saw something strange in a few pictures. We viewed them on the TV to get a larger image. You can imagine how surprised and excited she was when we discovered that we didn’t see any Ewoks, but they saw us, and had certainly taken an interest in her and her little brother. Maybe I’m a little wrong for lying to her and falsifying the pictures, but I don’t care. She’ll never forget the time she spent in the big woods with Ewoks.
