A polar-plane-based method for natural illumination of plants and trees
We introduce an illumination method for outdoor scenes containing plants and trees. Our method supports multiresolution plant and tree models based on random L-systems. The method...

Discriminant and Invariant Color Model for Tracking under Abrupt Illumination Changes
The output from a color imaging sensor, or apparent color, can change considerably due to illumination conditions and scene geometry changes. In this work we take into account the...

Shape Estimation in Natural Illumination
The traditional shape-from-shading problem, with a single light source and Lambertian reflectance, is challenging since the constraints implied by the illumination are not suffi...

Reconstructing the indirect light field for global illumination
Stochastic techniques for rendering indirect illumination suffer from noise due to the variance in the integrand. In this paper, we describe a general reconstruction technique tha...

Estimating Natural Illumination from a Single Outdoor Image
Given a single outdoor image, we present a method for estimating the likely illumination conditions of the scene. In particular, we compute the probability distribution over the su...
