Abstract (in Japanese) (See Japanese page) 
(in English) In the research field of Mixed Reality, there have been many studies on displaying virtual human characters in real scenery. "Human Billboards" are usually used when we want to show 2D human characters through an image-based method. However, a problem with conventional Human Billboards is that we cannot see the human characters from any arbitrary viewpoint. In this paper, we propose a new Human Billboard system where the characters' appearance changes with respect to the user's viewpoint. We first prepare several databases that contain about 1000 of 3D human models, as well as some prerecorded movies as input. Then, we run Chamfer Matching and DP Matching on the databases. This allows us to obtain frames of the input movies that show the human characters from the different angles.
