Outline of Final Research Achievements

For human detection against high dynamic range scenes, we proposed the new system with HDR camera. It contributes to the development of in-vehicle camera technology. We proposed color reproduction system for vivid color LDR illuminants. It makes illumination design easier. We proposed robust object tracking system against illuminant color changes. Even in difficult situations (e.g. color illumination stage) it can robustly track objects. We proposed estimation of multiple illuminant colors using color lines of single image. It contributes to the development of computer vision field. We proposed interaction system which can read both code and gesture information. It can contribute to the realization of a new interaction system.
