Fig. 24: Comparison of pigment distribution results based on different local murals.

From: Digital restoration of mural paintings from late Tang tomb M1373 in Xi’an based on hyperspectral analysis and image interaction processing

Fig. 24

a shows mural color distribution in local hyperspectral image calculated by spectral angle matching method, b shows corresponding mural color distribution in local color photo calculated by maximum likelihood estimation method. The elements in (a) were obtained from data captured by our team’s hyperspectral imaging scanning system for tomb murals, and no pre-existing external materials were used. The elements in (b) were obtained from data captured by our team’s camera, and no pre-existing external materials were used. The Fig. 24 is generated using the following software with valid licenses: ENVI6.0 Trial Version.
