| Abstract(in English) | In this paper, we propose a new method to estimate the distribution of shielding objects in scattering media by analyzing light transport which is measured by a pair of illumination and camera. This estimation problem is regarded as an inverse problem compared to the regular problem. Many solutions for this problem usually have a limitation which can not be applied for strong scattering media because it is difficult to deal with light propagation in this environment. In our method, many light paths are generated by random sampling of scattering points. We estimate the distribution of shielding objects by voting the likelihoods of existing the occluding object on each light path. We have evaluated the proposed method using simulated scene data and confirmed that the location can be roughly estimated. |
