This chapter has really rounded out our experience and drawn a line under our accomplishments. We learned to detect primitive shapes using the Hough transform. Then, we used OpenCV and Unity together to turn a pen and paper drawing into a physics toy. We have surpassed the things that even Q could make a pen do!

At this proud moment, however, our adventure must reach its conclusion. We might meet again. Look out for future books, webcasts, and presentations, to be announced on my website at http://nummist.com/opencv. Also, e-mail me at <[email protected]> to report issues, ask questions, and tell me how you are using OpenCV.

The book is ending now and I am waiting to find out whether I disappear into the sunset with a femme fatale or whether I have a melancholy debriefing with M.
