Abstract:
1. A method for determining a surface contamination level for a first surface, comprising the steps of: a computer receiving 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 determining whether dispersion of the pixel count across the range of color values, with regard to each color, exceeds a first threshold value; the computer determining 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 the computer receiving a second set of spectral information for the first surface, wherein the second 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 two; and the computer determining, with regard to the second set, whether the dispersion of the pixel count across the range of color values, with regard to each color, exceeds the first threshold value.
