用炭黑墨水书写并隐藏在文物中的古代文本的非侵入性数字恢复已被证明是难以捉摸的，即使使用先进的成像技术，如基于X射线的微型计算机断层扫描（micro-CT）。本文确定了一个关键的错误假设：微型CT数据无法捕获任何代表碳墨存在的信息。相反，我们展示了新的实验，表明微型CT中的碳墨水具有微妙但可检测的特征。我们展示了一种新的计算方法，该方法可以捕获，增强并使微CT中碳墨水创建的特征签名可见。这个以前“看不见”的碳墨水证据，现在可以成功地变得可见，这是一个发现，可以直接导致赫库兰尼姆丢失文本的非侵入性数字恢复。
The noninvasive digital restoration of ancient texts written in carbon black ink and hidden inside artifacts has proven elusive, even with advanced imaging techniques like x-ray-based micro-computed tomography (micro-CT). This paper identifies a crucial mistaken assumption: that micro-CT data fails to capture any information representing the presence of carbon ink. Instead, we show new experiments indicating a subtle but detectable signature from carbon ink in micro-CT. We demonstrate a new computational approach that captures, enhances, and makes visible the characteristic signature created by carbon ink in micro-CT. This previously "unseen" evidence of carbon inks, which can now successfully be made visible, is a discovery that can lead directly to the noninvasive digital recovery of the lost texts of Herculaneum.
