MR simulation for re-wallpapering a room in a free-hand movie

Abstract

This paper proposes a wallpaper replacement method in a free-hand movie. Our method superimposes computer graphics (CG) wallpaper onto a real wall region in the free-hand movie looking around a room. To extract wallpaper planes, ordinarily a special and expensive 3D survey instrument is required. However, there is usually no such instrument in homes or offices where many users want to experience wallpaper replacement simulation. To solve this problem, we extract the wallpaper region by an image segmentation technique with user interaction. By applying our method, wallpaper replacement can be easily achieved using only a handy camera and a PC. © 2014 Springer International Publishing.
