IGLANCE: interactive free viewpoint for 3D TV

The iGLANCE project aims at making interactive free viewpoint selection possible in 3D TV broadcasted media. This means that the viewer can select and interactively change the viewpoint of a stereoscopic streamed video. The interactivity is enabled by broad-casting a number of video streams from several viewpoints, consisting of a traditional 2D video and additionally depth information for each frame. Any desired view location in-between is generated by free viewpoint interpolation, using the depth information. The interpolated images are then displayed on a stereoscopic screen, giving a 3D impression to the audience. This article focuses on the broadcast chain, the decoding aspects and the view interpolation algorithm
