July 7th,2017: Day 2

After the morning meeting, we went to our adviser's office and learned more about using Envi. We learned about a few methods of imaging and then went to the reading room to practice on an ancient map of Korea. After about five hours of staring at Korea I switched to an ancient map of Taiwan. A PhD student, Di, taught us a few new things to do with Envi and that lasted up until the end of the day.

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 ...
