Wide Gamut Spectral Upsampling with Fluorescence
Physically based spectral rendering has become increasingly important in recent years. However, asset textures in such systems are usually still drawn or acquired as RGB tristimulus values. While a number of RGB to spectrum upsampling techniques are availa ...
2019Angular Color Prediction Model for Anisotropic Halftone Prints on a Metallic Substrate
Roger Hersch, Lin Yang, Petar Pjanic
Under specular reflection, non-isotropic halftones such as line halftones printed on an ink-receiving plastic layer superposed with a metallic layer change their colors upon in-plane rotation of the print. This color change is due to the orientation-depend ...
I S & T-SOC IMAGING SCIENCE TECHNOLOGY2019Laminated glazing with coloured reflection and high solar transmittance suitable for solar energy systems
Laminated and etched glazing unit for architectural integration of solar energy systems comprising a substrate delimited by two main faces and a multi-layered interference filter also delimited by two main faces, one main face of said substrate being adapt ...
2017Luminance maps from High Dynamic Range imaging: calibrations and adjustments for visual comfort assessment
Jan Wienold, Clotilde Marie A Pierson, Magali Bodart
Luminance maps created on the basis of High Dynamic Range Imaging (HDRI) is a technique increasingly used to study the visual environment. But creating HDR images with commercially affordable equipment requires an extensive calibration process to ensure th ...
2017Put on that colour, it fits your emotion: Colour appropriateness as a function of expressed emotion
Christine Mohr, Cynthia Marchand
People associate affective meaning with colour, and this may influence decisions about colours. Hue is traditionally considered the most salient descriptor of colour and colour-affect associations, although colour brightness and saturation seem to have par ...
Routledge Journals, Taylor & Francis Ltd2016Color reproduction, pattern hiding and image alternations with halftone prints on metal
We propose new methods for creating color or achromatic images that are printed with classical cyan, magenta, yellow and a white diffusing ink on a metallic substrate. We optimize the surface coverages of the cyan, magenta, yellow and white inks in order t ...
2016Human responsive daylighting in offices
This dissertation proposes a novel gaze-driven approach for dynamic discomfort glare assessments as a first step towards understanding human responsive comfort with respect to daylight. The objective was to observe the natural gaze behaviour in relation to ...
EPFL2015Color Reproduction with Juxtaposed Halftoning
Recently, non-standard inks have begun to make their way into the world of printing. Non-standard inks are printing materials which exhibit unusual effects such as angular color dependence, texture, or fluorescence. They are made of special-effect pigments ...
EPFL2015Print-based visual security features
Security features ensuring the authenticity of banknotes, checks, identity documents, diploma and business documents as well as of valuable goods are of high importance in today’s society. We briefly describe three security features that rely on color pr ...
