a shows color image of the mural after the background restoration, b shows color restoration results of red pigment without RGB-HSI color space correction, c shows color restoration results of red pigment with RGB-HSI color space correction, and d shows color restoration results of red, green, yellow pigments. The elements in Fig. 26 were obtained from data captured by our team’s camera, and nd the pre-existing elements in Figs. 15, 17, 19 were used. The Fig. 26 is generated using the following software with valid licenses: MATLAB R2024b (License No.: 40827055, MATLAB (Individual)).
