Real-Time 3-Dimensional Editing of an Occluded Object in a Free-Viewpoint Video
Ryo Hirai, Tadahiro Fujimoto (Iwate Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) A method has been proposed to generate a free viewpoint video from a multi-viewpoint video captured by a camera array with cameras arranged in a 2D grid pattern and apply real-time editing to a target object in the video. The target object and its background are purely extracted without blurred color impurities of occluding objects in real time from the free viewpoint video by giving focal planes to their respective positions in the 3D space. Then, the extracted target object is interactively edited by translating, rotating, and scaling in a 2D image plane, and merged with the extracted background to obtain a new free viewpoint video. In this study, we propose a method to extend the editing from a 2D plane to a 3D space.
