Abstract
This paper proposes a new blue screen matting digital solution, which employs “curved separating surfaces” in RGB colorspace. The “separating surface” model was examined by Jim Blinn and Alvy Ray Smith at the 1996 Siggraph conference and is the recognized model employed in two of the most common matting products used by the industry today. With this paper, we extend the concept from the earlier model, which was defined with coarse polygons, to curved surfaces that maintain a more natural pixel distribution of the foreground data against the background screen. A constrained grid surface patch (referred to as OGP) is introduced, which achieves a fast, practical computing solution for natural matte generation and background suppression. An additional solution called the extended matting problem is also presented that uses two additional curved separating surfaces for background spill removal.

bio
Yasushi Mishima is a researcher with the Digital Systems Division of Imagica Corp., Japan. Since joining the company in 1990, he has developed Primatte, a chromakeyer software and has been involved in the development of many other image processing software programs used in graphic applications. Mishima was a computer graphics engineer in Totsu AV Center in Japan before joining Imagica. From 1994 to 1997, he worked for Photron U.S.A. in San Jose. Mishima received a Bachelors degree in chemical engineering from Osaka University. He holds two U.S. patents in chromakeying technology.
