| 摘 要： | 石碑作为一种独特的石刻形式,源远流长,历代相承,具有清晰的发展脉络.现存的一些石碑已经破损,表面的文字和图案信息模糊不清,这些石碑文物不仅是艺术作品也具有重要的研究价值.利用获取的石碑高光谱数据,提出基于阈值的最小噪声分离变化算法分离了图像数据中的有效信息和噪声,提取了石碑的特征信息,并对提取图案上的颜料进行了分析,分析结果表明颜料为赭红的可能性比较大.

| Abstract: | Stone tablet is regarded as a special form of stone carving. It goes back to ancient times, passes all previous dynasties, and has a clear development veins. Some of the existing stone tablet has been damaged, and the text and pattern information on the surface are fuzzy and unclear. These cultural relics stele is not only the works of art, but also has important research value. Using the hyper-spectral data obtained from the stole, the minimum noise fraction change method based on the threshold is proposed , and the effective information and noise in the image data are separated;the feature information of the stone is extracted;the pattern on the extraction of the pigment is analysed. The results show that the pigment for the ruddy possibility is larger. |
