説明
In this paper, we propose a method to estimate the reflectance property from multi-focus images for light source reflected on the object. The blurred information of the light source on the surface is expected to be the practical method to estimate the reflectance property, even though various methods are proposed to estimate the reflectance property. However, the degree of the blurred information will be changed with the position of focus in the camera. Therefore, we introduce the light field camera which can change the position of the focus after the image are captured. In this research, we choose the image where the light source is focused on the object surface. Based on the blurred information of the focused light source, we estimated the reflectance property of the object. The estimated reflectance property is applied to inverse rendering for auto appearance valance.
