Selective de-animation video

At the SIGGRAPH 2012 conference, specialists from the University of California at Berkeley presented a semi-automatic selective de-animation video technique. The user marks parts of the video frame that should be static, and the rest of the objects move as before. This allows you to create various artistic effects: for example, the guitarist plays an absolutely fixed guitar.



Another case: when videotaping a female model, you can create a so-called cinematic portrait - something in between a photograph and a video. At the same time, the girl's figure remains absolutely motionless, but her eyes blink and her hair flutters in the wind. Such a video sequence can be glued together in an infinite loop with almost no distortion (see the video under the cut).

The algorithm opens up possibilities for creating various effects. For example, the "bottomless glass", which is never filled with water. The technology also allows you to improve the quality of the video when shooting with a permanent object in the frame (for example, a person's face), completely suppressing the vibration of the object in the frame. In this case, the operation of the algorithm can be compared with the image stabilizer.
