Wide-field image correction in systems that look through the atmosphere generally requires a tomographic reconstruction of the turbulence volume to compensate for anisoplanatism. The reconstruction is conditioned by estimating the turbulenc...
Screening for mild anomalous trichromacy using the Ishihara plates test [0.03%]

This study is intended to measure the geometry of the observer's color space when viewing a computer screen and to define individual variations from these data. A CIE photometric standard observer assumes that the eye's spectral efficiency ...

The distribution of colors across a surface depends on the interaction between its surface properties, its shape, and the lighting environment. Shading, chroma, and lightness are positively correlated: points on the object that have high lu...
Sensory representation of surface reflectances: assessments with hyperspectral images [0.03%]

Specifying surface reflectances in a simple and perceptually informative way would be beneficial for many areas of research and application. We assessed whether a 3×3 matrix may be used to approximate how a surface reflectance modulates th...
Accurate luminance and chromaticity controls of digital colors using CIE-based RGBW algorithms [0.03%]
基于CIE的RGBW算法在数字色彩亮度和色度控制中的应用研究
Ni Tang,Jiyong Wang,Baofeng Zhang et al.
Ni Tang et al.
Emerging high brightness of color displays and high signal-to-noise ratio of camera sensors require an addition of white (W) subpixels to ordinary red, green, and blue (RGB) subpixels. Conventional algorithms converting RGB signals to RGBW ...
Using equiluminance settings to estimate the cardinal chromatic directions for individuals [0.03%]
利用等亮度设置估计个体的主色度方向

Alex J Richardson et al.
Color information is processed by the retina and lateral geniculate along principal dimensions known as the cardinal directions of color space. Normal differences in spectral sensitivity can impact the stimulus directions that isolate these...
Task-dependent extraction of information from videos of iridescent and glossy samples [0.03%]
任务依赖的从虹彩和高光样本的视频中提取信息
Li Shiwen,Takuma Morimoto,Julie M Harris et al.
Li Shiwen et al.
We present an exploratory study on iridescence that revealed systematic differences in the perceptual clustering of glossy and iridescent samples that was driven by instructions to focus on either the material or the color properties of the...
Underwater image illumination estimation via an evolving extreme learning machine by an improved salp swarm algorithm [0.03%]
一种改进的水母群算法及其在水中图像光照估计中的应用
Junyi Yang,Mudan Cai,Chao Wang et al.
Junyi Yang et al.
Underwater images have chromatic aberrations under different light sources and complex underwater scenes, which can lead to the wrong choice when using an underwater robot. To solve this problem, this paper proposes an underwater image illu...
Radiative transfer equation-based color prediction and color adjustment strategies [0.03%]
基于辐射转递方程的颜色预测及颜色调修策略

Felix Glöckler et al.
This paper discusses different strategies for color prediction and matching. Although many groups use the two-flux model (i.e., the Kubelka-Munk theory or its extensions), we introduce a solution of the P N approximation for the radiative t...
