| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we describe a reflectance reconstruction method based on a small number of measurements in order to speed up reflectance measurement. Conventional method of reflectance measurement has a problem that it takes a lot of time to complete because it is necessary to perform sampling repeatedly changing the direction of light source and observation variously. In this paper, we propose a method to shorten the measurement time by adaptively determining the measurement strategy after each sampling. In this method, the next sampling direction is set as the sampling direction that maximizes the between-model variance based on the history of measured val- ues, which enables to complete the measurement of reflectance with a small number of samplings. By conducting simulation experiments on this method, we confirmed that this method can reconstruct reflectance precisely with a small number of measurements adaptively for each material. |
