"The dress" has provoked intensive commentary among psychophysicists, especially in relation to color vision. Researchers have shown that manipulating illuminance cues can influence the perceived colors of the dress. Here we investigate whether illusory shifts in brightness can shift color perception of the dress. Drifting achromatic gratings with fast off and fast on shading profiles are known...

Synthesis of heat exchanger networks (HENs) is inherently a mixed integer and nonlinear programming (MINLP) problem. Solving such problems leads to difficulties <span style="font-size: 10pt; color: #00...

This study investigated the effects of illumination conditions (lighting color and illumination intensity) and chromaticity contrast on reading performance with TFT-LCD screens. Results indicated that the illumination intensity and background color had significant effects on reading performance in experiment 1. In experiment 2, only text color significantly affected reading performance. However...

It is commonplace to use a 3 3 linear transform to map device RGBs to XYZs. Two particular types of transforms have been developed based on the assumptions that we either maximally ignorant or maximally prescient about the world. Under the maximum ignorance assumption, it is assumed that nothing is known about the spectral statistics of the world and so the best correction transform is the one ...

Introduction: The effects of accidents vary from minor injuries to fatalities and from insignificant damage to severe damage to the environment and property. In order to prevent accidents in the work place, the root causes of and events should be identified using a systematic method and the results should be published. The current study aims to investigate the given causes of an accident in ord...

Color images often must be color balanced to remove unwanted color casts. We extend previous work on using a neural network for illumination, or white-point, estimation from the case of calibrated images to that of uncalibrated images of unknown origin. The results show that the chromaticity of the ambient illumination can be estimated with an average CIE Lab error of 5∆E. Comparisons are made ...

This paper is concerned with a proposed color correction method called the Pixel Distribution Shifting Color Correction (PDSCC). This method employs a shifting process on the pixel distribution of a color image to correct its white reference point and ensure the white reference point is achromatic. The proposed method has been tested on numerous types of images which include indoor, outdoor, an...
