Google Launches Motion Stills For Apple’s Live Photos
Specifically designed for iOS, Google has launched a new photo app known as Motion Stills. It is similar to Apple’s own Live Photos, but Motion Stills has improved the image capturing by adding new features to Apple’s Live Photos format and has simplified the process of sharing the output images. The app uses an ingenious assemblage of algorithms and AI to evaluate the pictures captured in the Live Photos format and processes them in creative ways. The algorithm uses linear programming to calculate a virtual camera path, which is enhanced to reorganize videos, and burst as if they were filmed with a stabilization apparatus and a still background or creating cinematic pans to eliminate unsteadiness. Google has achieved a 40x speedup by using techniques such as decoupling of motion parameters, temporal sub-sampling, Google Research’s custom linear solver, GLOP and by computing low-resolution warp textures to perform real-time GPU rendering just like in a video game. The Motion Stills allay the videos captured before and after the photos by preparing the frames which are most in-focus and then finalizing the best start and end point for the loop of the videos.
Motion Stills will automatically categorize your Live Photos with all the murky work done behind the scenes. The app also resolves the problem of the lack of cross-platform support. It will now let you export the output movie clips as short videos or animated GIFs both of which can be shared across all the platforms. One of the difficult tasks which the Motion Stills has achieved is the separation of the background from the rest of the scene. When the foreground elements obstruct the substantial portions of the video, Google uses a method that classifies motion vectors into foreground (red) and background (green) in a temporarily consistent manner. They have used a torrent of motion models and then moved their motion approximation from simple to more complex models and swaying their results along the way.
Motion Stills is a live experience you get on your mobile. With no signals and at any place imaginable, you can see your results immediately. You can share your favourite clips by posting them on social media. It will help Google to enhance quickly on the technology and integrate new features into the existing products if required.
Try it out and check your creative skills. Be it at adventures or fun with family at home, you now have an app to show off your creative expertise. Meanwhile, Apple would be addressing a few Live Photos issues in its upcoming iOS 10. Till then make the best out of Motion Stills.
