Erasing Objects From Video In Real Time

Smoothly interpolating away objects in still pictures is impressive enough, but reader geoffbrecker writes with a stunning demonstration from Germany's Technical University of Ilmenau of on-the-fly erasure of selected objects in video. Quoting: "The effect is achieved by an image synthesizer that reduces the image quality, removes the object, and then increases the image quality back up. This all happens within 40 milliseconds, fast enough that the viewer doesn't notice any delay."

    We need this built into our televisions to automagically remove those network logo "bugs" and other crap they have started putting on the screen during the shows.

      In reality the networks wil use it to blur out any logo's from companys that do not sponsor the show. F1 cars will be red instead of filled with sponsors.

      Or stripping out the thousands of peaceful middle aged protesters and the hundreds of uninvolved pedestrians being tear gassed to show only the one or two violent people who actually have nothing to do with the protest.

      Next up, witnesses will disappear from police video to discredit them in court.

  2. Cool, but probably still has a ways to go. by suso · · Score: 3, Interesting

    Pretty good, but take note that all the examples where objects sitting on pretty flat colored backgrounds. I'd like to see what happens when you try to remove an object in a complex environment. Like removing a single person standing in a crowd.

      Take a look at the explanation part of the video. The background texture is tiled. You can see some strange deformation in the regular pattern where the object used to be. Also in the drain example there is a strange crater effect as the camera angle changes.

      It seems like smooth colour graduations work well, but patterned backgrounds have more obvious deformations.

  3. Do we still believe what we see? by gknoy · · Score: 4, Insightful

    This has some frightening ramifications for how much we believe video. Videos similar to the ones Wikileaks leaked, or news videos "live" on scene, could be doctored in near enough to real time that we consumers might never know it. Scary.

  4. Journalistic Integrity by Defenestrar · · Score: 3, Interesting

    Great - it'll start off by making eyesore real estate disappear from "live coverage," then be required as a precondition for live celebrity interviews (not just makeup to cover that acne), moving on to inconvenient points to the story that would take too much time and effort to explain, then images which might "disturb the children" (number of student bodies in Tienanmen Square?), and finally develop to ubiquitous studio-in-a-cameras such that we'll have little assurance of whether live coverage is fact or fiction.

    Of course that's just pessimism speaking. Really I'm looking forward to watching live reports without those obnoxious people waving at their mothers, or holding up witty slogans about taxation.
