US 2014/0193042 A1 · SURFACE CONTAMINATION DETERMINATION SYSTEM

Abstract

A computer receives a first set of spectral information for a first surface, wherein the first set of spectral information includes a pixel count for each color value of a range of color values, with regard to each color, measured at time one. The computer determines, with regard to the first set, whether dispersion of the pixel count across the range of color values, with regard to each color, exceeds a first threshold value. The computer determines, with regard to the first set, a surface contamination level based on at least whether the dispersion of the pixel count across the range of color values, with regard to each color, exceeds the first threshold value.
