Imager Update
I continued to tweak the code (and actually got it to work properly). After a brief break from the project, I realized how difficult it was to follow the code without extensive commenting… so, the updated code is extensively commented - at least from my perspective. I also moved the project folder to the SMAIG project and it now resides on GitHub.
Occlusion scores were derived by counting the number of pixels with a color code greater than .5 (0 = black and 1 = white in a gray-scale palette) - lower scores = greater occlusion. The images can all be regenerated using the SMAIG code and the spreadsheet in the folder.
