The Comprehensive Processing Methods on Reproducing of the Image of Relic on Subtle Levels

Abstract

Culture relics, as the remains of legacy in the development of human history, are unduplicated. And making the image of relics, therefore, is significant at protecting, studying and appreciating the cultural relics and even promoting the heritage of human civilization. Subtle level of relic image, as the main part for image duplication always reflects original characteristics and texture of the image. The relic’s density is adjusted to the maximum of the visual identification through centering the relics in the image for black and white points calibration. Adjusting tone curve can represent the relic’s texture to satisfy the requirements of the visual artistic appreciation in accordance with the concrete characteristics of the cultural relic’s image. Based on color adjustment, the detail expression and level texture of the relic can be emphasized. Using image processing method furthers refined correction to ensure the whole density of image and equilibrium of the level. Sharpen the image of relics to intensify the subtle level in accordance with Mach Band Effect. These basic principle and method such as level tone and color adjustment combined with the relevant image processing methods is applied comprehensively to the image duplication, which can represent and promote the subtle level of the image as well as the relics’ style with high quality.
