| Outline of Final Research Achievements |
This research aims to analyze geometric and photometric properties of subsurface scattering and volume scattering from 8-D light transport which consists of 4-D light field illumination and 4-D light field recording. For the illumination, we have developed an effective calibration method and a new illumination system which simultaneously projects different patterns onto different depths. For recording, a light field camera is used and the measured 4-D light field is analyzed by a new segmentation method which introduces spatial and angular smoothness as a constraint. Moreover, we have tried temporal analysis of light transport with a new temporal dimension using a ToF camera which becomes common during the research period and we have confirmed that material can be estimated from the time delay of light transport.
