Rendering photorealistic virtual objects from their real images is one of the main research issues in mixed reality systems. We previously proposed the Eigen-Texture method (K. Nishino et al., 1999), a new rendering method for generating virtual images of objects from their real images to deal with the problems posed by past work in image based methods and model based methods. Eigen-Texture method samples appearances of a real object under various illumination and viewing conditions, and compresses them in the 2D coordinate system defined on the 3D model surface. However, we had a serious limitation in our system, due to the alignment problem of the 3D model and color images. We deal with this limitation by solving the alignment problem; we do this by using the method originally designed by P. Viola (1995). The paper describes the method and reports on how we implement it.
Nishino et al. (Fri,) studied this question.
