Stars form in dense clouds of interstellar gas and dust. The residual dust surrounding a young star scatters and diffuses its light, making the star's " cocoon " of dust observable from Earth. The resulting structures, called reflection nebulae, are commonly very colorful in appearance due to wavelength-dependent effects in the scattering and extinction of(More)
This paper addresses the problem of reconstructing the 3D structure of planetary nebulae from 2D observations. Assuming axial symmetry, our method jointly reconstructs the distribution of dust and ionized gas in the nebulae from observations at two different wavelengths. In an inverse rendering framework we optimize for the emission and absorption densities(More)
This paper presents a method for reconstructing the 3D distribution of dust densities in reflection nebu-lae based on a single input image using an analysis-by-synthesis approach. In a reflection nebula, light is typically emitted from a central star and then scattered and partially absorbed by the nebula's dust particles. We model the light transport in(More)
