Document Restoration's main focus is to study old documents and analyze them using several techniques. We are currently working on finding corrections using pigment analysis and imaging enhancements on the Selden Map of the Ming Dynasty dating back to the 1600's. We will also be working with faded and illegible texts. These documents have either been erased, covered up, or have faded. Spectral imaging creates more precise and useful information than regular red, green, blue (RGB) imagery. For example, hyper-spectral and multi-spectral imaging are used to make items more legible and more visible to the human eye. Multi-spectral imaging uses less than 50 color bands during processing, while hyper-spectral imaging uses several hundred bands during processing. Other analysis techniques used to get more information about a part of a document include Principal Components Analysis (PCA), Spectral Angle Mapper (SAM), and Mahalanobis Distance. These techniques can also be applied to illegible texts, typically being palimpsests, a text that has had its writing removed and replaced.
The morning meeting wasn't too bad today, we finished up the abstracts and had a good chat. Paige and I had the most eventful morning we've ever had, we got to go to all four floors and visit all of the labs trying to find people. We also talked to Ryan to let him know how disappointed we were with him but he's fine. We've been putting the final touches on the presentation and it looks pretty good. Peter, Ashley, and Tristan came up for lunch and we analyzed life's deepest mysteries like if Peter's shorts were shorter than mine, which they definitely were, and each others social media pages. It was a pretty good lunch. I've been doing a lot of reading today in the absence of work. Going back and forth between a dry book and a semi-dry presentation is absolutely exhilarating. Paige has been making a lot of small changes to the slides and I'm good with that, they aren't major and she's right to do most of them so I'm glad she sees some of these
