The README.md in GitHub still says OpenCV is required, and I also make mention of the Motion subsystem in the project. I started with Motion, tried to advance things with OpenCV, however the current state of the software project has a homebrew imaging solution.
I need to finally make a decision on what the appropriate path forward is. I'm going to do some tweaking on the homebrew solution - if it (finally) works I'll clean up the documentation and point everything to homebrew. Otherwise I'll need to decide between OpenCV and Motion... likely OpenCV.
