Image-based reconstruction of heterogeneous media in the presence of multiple light-scattering

Ludwic Leonard Méndez, Rüdiger Westermann

Abstract: Highlights•Reconstruction of volumetric media in the presence of multiple light scattering.•Physically based differentiable volume rendering with improved path sampling.•Initial solution built with a simpler direction-dependent emission field.•Occupancy mask used for constraining the volume in object space.•Loss variance is reduced by using an exponential moving average.
