RGB Color Calibration for Quantitative Image Analysis: The “3D Thin-Plate Spline” Warping Approach

Sensors, 2012
In the last years the need to numerically define color by its coordinates in n-dimensional space has increased strongly. Colorimetric calibration is fundamental in food processing and other biological disciplines to quantitatively compare samples’ color ...

Optimized clustering method for spectral reflectance recovery

Frontiers in Psychology, 2022
An optimized method based on dynamic partitional clustering was proposed for the recovery of spectral reflectance from camera response values. The proposed method produced dynamic clustering subspaces using a combination of dynamic and static clustering,

AKARI's infrared view on nearby stars : Using AKARI Infrared Camera All-Sky Survey, 2MASS, and Hipparcos catalog [PDF]

, 2010
--Results-- We found that the (B-V) v.s. (V-S9W) color-color diagram is useful to identify the stars with infrared excess emerged from circumstellar envelopes/disks.

Neighbouring Color Dependence Matrix for Image Analysis : Application to homogeneous and heterogeneous areas detection and characterization

ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2008
A new method for color texture characterization and color texture region detection is presented. This method, which we will name NCDM (Neighbouring Color Dependence Matrices), is the extension to color textures of the NGLDM (Neighbouring Gray Level ...

Color naming and the shape of color space [PDF]

Language, 2009
Color naming in the world’s languages has traditionally been viewed as reflecting either a universal set of focal colors, or linguistic relativity. Recently, a different view has gained support: color naming may be accounted for in terms of the overall shape of perceptual color space.

Investigation of the Hue–Wavelength Response of a CMOS RGB-Based Image Sensor

Sensors, 2022
In this study, a non-linear hue–wavelength (H-W) curve was investigated from 400 to 650 nm. To date, no study has reported on H-W relationship measurements, especially down to the 400 nm region.

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

Population Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using
