A Fluorescent lamp with Single layer Phosphor for Simulating the CIE Illuminant D65

Perceived color shift of ceramics according to the change of illuminating light with spectroradiometer

PURPOSE Perceived color of ceramics changes by the spectral power distribution of ambient light. This study aimed to quantify the amount of shifts in color and color coordinates of clinically simulated seven all-ceramics due to the switch of three ambient light sources using a human vision simulating spectroradiometer. MATERIALS AND METHODS CIE color coordinates, such as L*, a* and b*,of cera...

Visual simulating dichromatic vision in CIE space

Dichromatic vision is due to the loss of one of the three cone pigments: the L type in protanopes, the M type in deuteranopes, and the S type in tritanopes. In this paper, we show that the dichromatic vision can be simulated by applying transformation to image in CIE x, y chromaticity space. We base our work on the past experiments on unilateral color blind (color blind in one eye) people which...

Fluorescent Lamp Modelling for Voltage Fluctuations

Fiat Lux: A Fluorescent Lamp Tkansceiver

The prevalence of electric discharge illumination has led us to consider ways to use discharge lamps for communication. This paper describes an optical transceiver system which transmits by modulating the lamp arc. The prototype power electronic lamp ballast uses a pulse frequency modulation scheme which ensures no perceptible flicker.

Efficient illuminant correction in the local, linear, learned (L3) method

To speed the development of novel camera architectures we proposed a method, L (Local, Linear and Learned), that automatically creates an optimized image processing pipeline. The L method assigns each sensor pixel into one of 400 classes, and applies class-dependent local linear transforms that map the sensor data from a pixel and its neighbors into the target output (e.g., CIE XYZ rendered und...
