The Effect of Hydration on Urine Color Objectively Evaluated in CIE L*a*b* Color Space [PDF]
Frontiers in Nutrition, 2020 Urine color has been shown to be a viable marker of hydration status in healthy adults. Traditionally, urine color has been measured using a subjective color scale.

The non-Riemannian nature of perceptual color space. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance For over 100 y, the scientific community has adhered to a paradigm, introduced by Riemann and furthered by Helmholtz and Schrodinger, where perceptual color space is a three-dimensional Riemannian space.

A dichotomy color quantization algorithm for the HSI color space [PDF]
Scientific Reports, 2023 Color quantization is used to obtain an image with the same number of pixels as the original but represented using fewer colors. Most existing color quantization algorithms are based on the Red Green Blue (RGB) color space, and there are few color ...

Image Clustering with Optimization Algorithms and Color Space. [PDF]
Entropy (Basel), 2018 In image clustering, it is desired that pixels assigned in the same class must be the same or similar. In other words, the homogeneity of a cluster must be high. In gray scale image segmentation, the specified goal is achieved by increasing the number of

Modeling color preference using color space metrics
Vision Research, 2018 Studying color preferences provides a means to discover how perceptual experiences map onto cognitive and affective judgments. A challenge is finding a parsimonious way to describe and predict patterns of color preferences, which are complex with rich individual differences.

Delving Deeper Into Color Space [PDF]
i-Perception, 2018 So far, color-naming studies have relied on a rather limited set of color stimuli. Most importantly, stimuli have been largely limited to highly saturated colors.

Color Vision: Decoding Color Space [PDF]
Current Biology, 2021 A new study has used magnetoencephalography to track cortical responses to color as they emerge in time. Similarities and differences within these neural responses parallel characteristics of the perceptual experience of color.

Underwater Image Enhancement via Medium Transmission-Guided Multi-Color Space Embedding [PDF]
IEEE Transactions on Image Processing, 2021 Underwater images suffer from color casts and low contrast due to wavelength- and distance-dependent attenuation and scattering. To solve these two degradation issues, we present an underwater image enhancement network via medium transmission-guided ...
