July 24th, 2017: Day 13

During the morning meeting we just had a recap of the week, nothing too exciting. Paige was late so I was sad and lost until she showed up. I met with Roger this morning to discuss what we'll be doing with his data. He's been studying the Jubilee Palimpsest. His way of analyzing data and his explanations about each procedure are completely different from Dave's. I've been struggling somewhat to bring out the under-text, mainly because my computer has been stuck on the 0% done loading bar for the past 10 minutes but also because this project is such a turn around from what we've been doing with Dave. After a few days I'm sure I'll pick it up and understand what's going on but until then I plan to mess with functions until I know each of their use. It's like the first day again, confusing and scary. Roger has been in and out all day checking on us so it's been helpful with him answering questions and then cutting us loose to try and fail. Hopefully tomorrow will be better along the lines of figuring things out. I'm mostly excited for the field trip Thursday so I've been thinking about that all day! I don't have a large amount of data to post about the palimpsest but I do have a few results that I'll add in later.

These are two results I have, the first one being an SAM result using the under-text as a region of interest. The second image is a PCA result done using bands 4,5,6. Neither of them show the under-text perfectly but they're a start

Outline

Intro Background: We are working to uncover illegible text from the "Jubilees Palimpsest" and find corrections and later additions on the Selden Map of China     Purpose/Technique: We use hyper-spectral imaging (several narrow spectral hundred bands) and multi-spectral imagining (fewer than 50 bands) The images are digitally processed and combined to create images with more characters that are legible than those in the regular RGB image Processing tools include Principle Components Analysis (PCA), Spectral Angle Mapper (SAM), Spectral Profiles   Selden Map Background: The Selden Map dates back to the early 17th Century during the Ming Dynasty The map includes approximately 15 countries and shows a system of navigational routes China, Borneo, Japan, Korea, and Taiwan are five countries with the most significant results Focus/Results: Green corrections in Borneo, Korea, Taiwan, and Rivers of North China Missing texts and names of ports in B...

July 25th, 2017: Day 14

I have nothing to report about the morning meeting. We got new data from Roger and we spent a lot of the time just making image cubes. We also visited the 3D printer to make a part that Peter and Ashley needed while our files were loading. Today has mainly consisted of renaming things and making image cubes and asking David Lewis for help. Thank goodness for David Lewis. We haven't created any new images so unfortunately nothing exciting to post in the blog today..

Abstract Rough Draft

 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, hy per-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 ...
