Mobile Real-time Video Segmentation

Mobile Real-time Video Segmentation

Video segmentation is a widely used technique that enables movie directors and video content creators to separate the foreground of a scene from the background, and treat them as two different visual layers. By modifying or replacing the background, creators can convey a particular mood, transport themselves to a fun location or enhance the impact of the message. However, this operation has traditionally been performed as a time-consuming manual process (e.g. an artist rotoscoping every frame) or requires a studio environment with a green screen for real-time background removal (a technique referred to as chroma keying). In order to enable users to create this effect live in the viewfinder, we designed a new technique that is suitable for mobile phones.
