  1. \({P}_{k}\): The area proportion of the monochromatic region k in the whole five basic color area
  2. \({F}_{k}\): It represents the score number of the cortical preservation status assessment in the monochromatic region k calculated by the membership function
  3. \(F\): It represent the overall assessment score of the artifact
