In this work, a critical review of the current nondestructive probing and image analysis approaches is presented, to revealing otherwise invisible or hardly discernible details in manuscripts and paintings relevant to cultural heritage and archaeology. Multispectral imaging, X-ray fluorescence, Laser-Induced Breakdown Spectroscopy, Raman spectroscopy and Thermography are considered, as techniques for acquiring images and spectral image sets; statistical methods for the analysis of these images are then discussed, including blind separation and false colour techniques. Several case studies are presented, with particular attention dedicated to the approaches that appear most promising for future applications. Some of the techniques described herein are likely to replace, in the near future, classical digital photography in the study of ancient manuscripts and paintings.
在这项工作中，对当前的无损探测和图像分析方法进行了批判性综述，以揭示与文化遗产和考古学相关的手稿和绘画中那些原本不可见或难以辨别的细节。文中考虑了多光谱成像、X射线荧光、激光诱导击穿光谱、拉曼光谱和热成像等作为获取图像和光谱图像集的技术；接着讨论了用于分析这些图像的统计方法，包括盲分离和伪彩色技术。还介绍了几个案例研究，特别关注那些对未来应用看起来最有前景的方法。本文所述的一些技术在不久的将来可能会在古代手稿和绘画研究中取代传统的数码摄影。
