This is not finished. It is barely started. I wrote it to teach myself about Qt.

• The finalize button doesn't do anything.
• The the calculation for 'average' color is just silly.
• I have a feeling that this will end up as a Qt/OpenCV hybrid.

You'll need Qt 4. Run 'qmake' (often located at /usr/lib64/qt4/bin/qmake) to get a Makefile, then run 'make' and you'll have an executable under the 'build' directory.

Future Work:

• Organic cap placement with an edge detector (canny/HOG) and a naive fill algorithm.
• Implement a 'dominant color' algorithm, instead of average color.
• Limit number of colors (color binning).
• Implement image segmentation (a la: http://web.cse.ohio-state.edu/~jwdavis/Publications/cvpr11a.pdf)
• Give a useful summary:
  • Listing of caps needed (how many of each color).
  • How big the surface area will need to be.
  • How much beer money you will throw away on this project.
  • Animations, because why not?
