Paper Abstract

A method to reproduce images on an object under various observation geometries is presented. In this method, a multispectral image sequence is captured with rotating the object under a point light source, where spectral distribution and the position are measured. The diffuse and specular reflection images are decomposed from the captured images based on the dichromatic reflection and the Lambertian models. The angular distribution of reflected light is obtained by the decomposed images, and the images under new observation geometry are synthesized by using light-ray rearrangement technique. In the experiments using two types of 2D objects, leather and fabric, it is confirmed that synthesized images under new illumination geometry are almost the same as the images actually captured under the new geometry.
