| Outline of Final Research Achievements |
We studied a set of images of an object taken under multispectral and multidirectional light sources in order to unify shading analysis and color analysis. Specifically, we (1) developed multispectral light stages, (2) showed the structure inherent in the set of images under multispectral and multidirectional light sources, and (3) developed a method for efficiently acquiring the set of images. In addition, we tackled some applications to image understanding, recognition, and synthesis such as (4) shape and reflectance recovery, (5) material recognition, and (6) image-based relighting.
