HDR-VDP-2: A Calibrated Visual Metrics for Visibility and Quality Predictions in All Luminance Conditions
A metric for predicting visible differences (discrimination) and image quality (MOS) in high-dynamic-range images. The metric is based on new contrast sensitivity measurements and calibrated against several datasets. The visibility predictions are shown to be improved compared to the original HDR-VDP and VDP metrics.

A Versatile HDR Video Production System
An optical architecture for HDR imaging that allows simultaneous capture of high-, medium-, and low-exposure images, and an HDR merging algorithm that avoids undesired artifacts. This paper explains implementation of a prototype HDR-video system and present sresults from the acquired HDR video.

Perceptually Based Tone Mapping for Low Light Conditions
A perceptually based algorithm for modeling the color shift that occurs for human viewers in low-light scenes. Known as the Purkinje effect, this color shift occurs as the eye transitions from photopic, cone-mediated vision in well-lit scenes to scotopic, rod-mediated vision in dark scenes.

Illumination Decomposition for Material Recoloring With Consistent Interreflections
Changing the color of an object is a basic image-editing operation, but a high-quality result must also preserve natural shading. This approach decomposes illumination into direct lighting and indirect illumination from individual materials to consistently modify material colors and their associated interreflections.
