Color Images Visible Under UV Light

Fluorescent inks allow us to create color images visible only under UV light. This paper proposes spectral prediction, gamut mapping, and juxtaposed half-toning methods specifically adapted to fluorescent ink halftones.

Visual Equivalence: Towards a New Standard for Image Fidelity

Visual equivalence occurs when noticeably different images convey the same scene appearance to an observer. This paper analyzes this phenomenon for illumination transformations and proposes a metric for novel rendering optimizations.

The Influence of Shape on the Perception of Material Reflectance

The shape of an object has a significant influence on the perception of its material. 3D modeling applications should offer material visualization and editing directly on the target object.
