Mr. Messinger introduced the Principle Componants Analysis (PCA) program to Madi and I during our morning meeting. The PCA programs are designed to identify a cooridnate system to best fit given data. In the case of using ENVI for color identification, each color in a document are a coordinate and PCA changes the coordinate system (the coordinates of the graph) to best fit the color data distribution.
So the majority of our work today was running Di initially gave us through PCA. We were able to clear up a lot more of the images and found more hidden text with PCA and image enhancement tools. We also checked some of each other's work and took a long walk at the end of the day to clear the headaches we got while staring at the computer screens for hours on end.
