Frequency-Space Decomposition and Acquisition of Light Transport under Spatially Varying Illumination
Published on 2012-11-123017 Views
We show that, under spatially varying illumination, the light transport of diffuse scenes can be decomposed into direct, near-range (subsurface scattering and local inter-reflections) and far-range t
