Reference Data Set of Human Skin Reflectance

Abstract

This data set contains 100 reference reflectance spectra of human skin, spanning the wavelength region from 250 nm to 2500 nm. The spectra were acquired with a commercial spectrophotometer and are directly traceable to the national scale for directional-hemispherical reflectance factor.

An Evaluation Framework for Spectral Filter Array Cameras to Optimize Skin Diagnosis

“…A set of (10,000) [39] skin reflectances is generated using a Monte Carlo skin model and compared to a Munsell reflectance patch database [40,41] for training the spectral reconstruction. A database of spectral measurements of skin reflectances (100 measurements) [42] is used for testing the spectral reflectance reconstruction. The spectral reconstruction accuracy is compared numerically using Root Mean Square Error (RMSE) and ΔE00 color differences [43].…”

“…For the validation if the spectral reconstruction another set based on skin reflectances was used. These skin reflectances (test set) are measured using a spectrophotometer and illumination corrected as described in [42].…”

“…This Figure allows comparison of the area covered by all sets and highlights three reflectances for each dataset. It includes the database of 100 measured skin reflectances [42], 10000 Monte Carlo simulated reflectances and the Munsell reflectances color patches [40,41].…”

Reference Data Set and Variability Study for Human Skin Reflectance

“…NIST published a reference data set of 100 reflectance spectra of human skin, spanning the wavelength range from 250 nm to 2500 nm (Cooksey et al, 2017). The spectra are directly traceable to the national scale for directional-hemispherical reflectance factor.…”

“…The spectra are directly traceable to the national scale for directional-hemispherical reflectance factor. The methods of data collection, processing, and estimating uncertainties is described extensively in Cooksey et al, 2017. It is briefly summarized below.…”
