TL;DR: The new model, which is based on a combination of local and global anchoring of lightness values, appears to provide an unprecedented account of a wide range of empirical results, both classical and recent, especially the pattern of errors.
Journal ArticleDOI
Real world illumination and the perception of surface reflectance properties
TL;DR: The findings suggest that subjects do use stored assumptions about the statistics of real-world illumination to estimate surface reflectance, and that the visual system's assumptions about illumination are of intermediate complexity, rather than of high complexity.
Journal ArticleDOI
Two methods for display of high contrast images
TL;DR: Two methods for the improved display of high-contrast images using a sigmoid function for contrast compression and interactively adjusts the displayed image to preserve local contrasts in a small “foveal” neighborhood are developed.
Journal ArticleDOI
Human facial illustrations: Creation and psychophysical evaluation
TL;DR: These studies show that the facial illustrations and caricatures generated using the techniques presented are as effective as photographs in recognition tasks.

Toward a perceptual theory of transparency.

TL;DR: Results demonstrate that the visual system uses Michelson contrast as a critical image variable to initiate percepts of transparency and to assign transmittance to transparent surfaces.
