Abstract

The invention discloses a high-fidelity digital restoration method for fading color murals, which includes a comprehensive mural paint database composed of basic pigment samples used in murals, fading simulation experiment samples and mixed pigment samples constructed by double-constant Kubelka-Munk theory. As a reference for the identification of mural paints; obtain the visible spectrum images of ancient murals; render the visible spectrum images to obtain the corresponding color RGB images; use the deep learning segmentation model unet to finely segment the color RGB images; calculate the representativeness of each sub-region Average spectral reflectance, and extract the spectral features of each sub-region; through feature matching, carry out pigment identification and analysis on each sub-region; based on the pigment recognition results and the representative average spectral reflectance of each sub-region, carry out color high-fidelity for each sub-region Restoration; by setting the adjustment parameter alpha, the simulated reproduction of fading and discoloration of color murals is realized; finally, high-fidelity digital restoration of faded and discolored mural colors is completed.
