Effect of Peak Luminance on Perceptual Color Gamut Volume
Fu Jiang, Munsell Color Science Laboratory, Rochester Institute of Technology and Apple Inc.

Read paper Effect of Peak Luminance on Perceptual Color Gamut Volume

How the peak luminance level of a display impacts its color reproduction capability would depend on how the image is processed by the display and the definition of color reproduction capability. In this talk, we will discuss the impact of peak luminance level on perceptual color gamut volume based on psychophysical study.

Fu Jiang received his PhD from the Munsell Color Science Laboratory at RIT in March 2021. His dissertation focused on High-Dynamic-Range (HDR) Display perception; color gamut volume model, and perceptual diffuse white level in HDR display; perfect "black" in HDR display; and the simultaneous dynamic range in our visual system. He currently works at Apple Inc. as a display metrology engineer.

Predicting the Reflectance and Transmittance of Translucent Dental Resins
Vincent Duveiller, Université Jean Monnet - Saint-Etienne

Read paper: Reflectance and Transmittance of Flowable Dental Resin Composite Predicted by the Two-flux Model: On the Importance of Analyzing the Effective Measurement Geometry

The aesthetic appearance of dental repairs is a priority for most patients. However, the high translucency of dental materials makes their appearance difficult to predict. This presentation discusses the adaptations that can be made to simple optical models to better predict the reflectance and transmittance of translucent dental composite resins.

Vincent Duveiller is a 2nd year PhD student studying the reproduction of the appearance of teeth using translucent dental composite resins. His research focuses on the study and implementation of optical models, the spectral measurement of reflectance and transmittance factors, and the optical properties of different translucent dental materials.

Flying Grey Ball Multi-illuminant Image Dataset for Colour Research
Hoda Aghaei, Terramera

Read JIST-first paper: A Flying Grey Ball Multi-illuminant Image Dataset for Colour Research

For research in the field of illumination estimation and colour constancy, there is a need for ground truth measurement of the illumination colour at many locations within multi-illuminant scenes. This talk proposes a practical approach to obtaining such ground truth illumination data. The method involves using a drone to carry a grey ball of known percent surface spectral reflectance throughout a scene while photographing it frequently during the flight using a calibrated camera. In total, the dataset contains 30 scenes with 100 illumination measurements on average per scene, which is available for free download.

Hoda Aghaei is a machine learning engineer at Terramera Inc. The main focus of her work is computer vision and data analysis problems in agricultural applications. She received an MS in computer science from Simon Fraser University, where she worked under the supervision of Prof. Brian Funt.
