Abstract

This paper proposes a wallpaper replacement method in a free-hand movie by using Mixed-Reality (MR) technique. Our method overlaps virtual wallpaper onto a real wall region in a movie that is taken by handheld camera looking around a room. In an ordinary way, 3D models of the target room are required. However, such special and expensive 3D survey instrument is not available in homes or offices where many users demand for a wallpaper replacement simulation. We solve this problem to extract a wallpaper region by using image segmentation technique with user interaction. Image segmentation technique can extract a target objects that include a thin one from a source image with an appropriate user interaction, and requires no special equipment like a 3D survey instrument. By applying our method, wallpaper replacement can be easily realized by using only a handy camera and a PC.
