This paper considers an objective Picture Qualip Scale for color images (PQScolor). PQScolor approximates the mean opinion score satisfactorily, it takes into account the color perception by using color direrence and the properties of visual perception f o r global features and for locczlized disturbances. There are two type systems, PQScolorl is based on Godlove's color difference and PQScolor2 is based on H, V, C signal difference. The correlation coeficient between PQScolor(1,Z) and MOS is more than 0.9, which is very high compared to the value 0.34 obtained for the mean color diference scale.

Raman spectroscopy was employed to investigate six Imperial China Engraved Coiling Dragon stamps non‐destructively. The results have shown that (1) the main colors (yellow, green, scarlet, brown, vermilion, and blue) on the six stamps were all prepared from inorganic pigments, including chrome yellow, chrome orange, Prussian blue, red lead, magnesium sulfate hydrate, and ultramarine blue. (2) Raman spectrometer has been allowed for successfully identifying the molecular structure of the pigments printed on the six examined stamps, suggesting that such a dual analytical approach could satisfy the need for pigment identification on stamps. (3) The finding that certain pigments were intentionally mixed to produce a whole different hue or color, the mechanism of which could be explained by theories of chromatology and metamerism, also provides new insight into the future conservation, authentication, and restoration of the early printings.

This paper introduced a laboratory management system, fingerprinting to pass the experiment verify the identities and automatically assign the more control over the wireless send instructions to the source control location to make experiments, and arm control unit will regularly monitor the situation in the experiment, on the high security. the intelligent all-weather.
