Abstract

While able to measure the red, green, and blue channels, color imagers are not true spectral imagers capable of spectral measurements. In a previous paper, it was demonstrated that an estimate of a low resolution visible spectra of a naturally illuminated outdoor scene can be estimated from RGB values measured by a conventional color imager. In this paper we present a refined algorithm and document results in a study to estimate visible source spectra from solar illumination scenes using reflectance spectra generated from the USGS data base.
