Acquiring Scattering Properties from a Sigle Image

Acquiring accurate scattering properties is critical for rendering translucent materials such as milk, smoke, human skin and so on.
To acquire the scattering properties, complex optical system and many observations have been required.
In addition, the phase function, which determines the distribution of scattering directions, plays a significant role in the appearance of the material.
While there are many techniques to acquire BRDF, there are only a few methods for the non-parametric phase function.
We propose a distinctive scattering theory that approximates the effect of single scattering to acquire the scattering properties including non-parametric phase function from a single image.
Furthermore, in various experiments, we measured the scattering properties from several real media and rendered images of these materials to evaluate the effectiveness of our theory.
