“Chroma keying between integral photography images” by Yanaka, Momose and Yoda

Chroma keying is a well-known technique for mixing two images in which a specific color of the foreground image is made transparent. When this technology is applied to integral photography (IP) images, each of which is a textured image in which images taken from hundreds of angles are integrated, it is very useful. IP is an ideal 3D display method because parallax in all directions can be obtained without the need for wearing special glasses. Moreover, it needs only simple hardware consisting of an LCD and a fly’s eye lens. In particular, in the case of the extended fractional view (EFV) method [1][2], an inexpensive ready-made fly’s eye lens can be used. Animation is also possible by displaying frames successively. However, creation of IP images is computationally intensive because multi-viewpoint rendering, in which a large number of images are observed from hundreds of viewpoints, is necessary. Therefore, we developed a chroma keying technology to reduce the processing time. By creating the foreground IP images and the background IP images separately and combining them later, the processing time could be reduced greatly, especially when the background was stationary.
