Identifying Manipulated Images

Posted by CmdrTaco on from the check-that-out dept.

Jamie found a cool story at MIT Tech Review. (As an aside, it sits behind an interstitial ad AND on 2 pages: normally I reject websites that do that, but it's a slow news day, so I'm letting it through.) Essentially, software is used to analyze light patterns in still photographs. Once you can figure out where the light sources are, it becomes a lot easier to determine if an image has been photoshopped.

    No, more like junior is trying to emulate father but doing a terribly half-assed job of it.
