 Display of High-Contrast Images using Models of Visual Adaptation

Two techniques for display of high-contrast images: layering scales three image layers independently, and foveal display for best display of a region indicated by the mouse.

 A Visibility Matching Tone Reproduction Operator for High Dynamic Range Scenes

A tone-reproduction operator that preserves visibility in high dynamic range scenes. The method incorporates models for human contrast sensitivity, glare, spatial acuity, and color sensitivity.

 Validating Global Illumination Algorithms and Software

Photographic images of real-world environments were compared to synthetic images of those environments in order to evaluate the accuracy of our lighting simulation both qualitatively and quantitatively.

 Composite Lighting Simulations with Lighting Networks

This extension to multi-pass global illumination algorithms allows flexible combination of the advantages of several algorithms by connecting them in the form of a dataflow graph.
