Some ancient murals were found to be repainted on the surface of original form multi-layer murals. The patterns layer are great significance for studying social and cultural behavior in that time. hyperspectral imaging covers visible near-infrared bands, which has advantages information extraction Therefore, a method study transmission performance simulated mural samples is proposed. By making samples, mineral pigment painted covered with 0-11 different layers lime water. Then collected images, principal component analysis band calculation used analyze enhancement effect by results show certain transmittance interior can enhance internal information. research support some extent.
