August 8th, 2017: Day 24

David Lewis really sparked up the morning meeting today. He brought in his projects from when he was an intern in 2014. Matt and David Lewis gave me and Paige notes for our presentation after we ran through it for them. Anjana was in the room too but I don't think she had too much to say. Dave and Roger came in during the morning so we could give another practice presentation to them.We decided to just run through it instead. The rest of the day was spent adding explanations to images and deciding who says what. Paige is remaking her massive map she stitched together from the VNIR images but this time it's going to be inverse colors. I think after that's done then our final days will be spent practicing the presentation.

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...

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 ...

August 16th, 2017: Day 30

Today was the final full work day!!!!! During the morning meeting we talked about the program and how it could be made better. After that, Paige and I watched Peter and Ashley's presentations and gave them some feedback. We looked at Roger's data for the rest of the morning until lunch time. We watched Aditi and Titus' presentations during the afternoon.
