Google has created an application for iOS that the photos of Apple Live Photo’s so stuck together that there is a smooth moving poison. For this makes it locally on the iPhone using an algorithm to stabilize pictures which do not require internet connection.

To achieve a technique which lead to the calculation of the device itself, the algorithm uses linear programming to calculate a virtual path that the camera would have made ​​if there is a stabilization system was used during filming. While the image on the background should be quieter than the foreground, making it appear completely relaxed.

Google’s challenge was to techniques that are normally used by distributed computing to run on a mobile phone. In addition, the company managed by optimizations to achieve a speed gain of forty times. The app uses the GPU as if there should be rendered textures in real time for a game.

In order to make better loops in which the foreground does move, makes Motion Stills difference between foreground and background, something that according to it is inconvenient Google’s Research Blog as the foreground occupies a large part of the image. The method classifies motion vectors between foreground and background after several motion models estimate what are the main results

The app is to get through the App Store for iOS devices.
