This chapter has really rounded out our experience and has drawn a line under our accomplishments. You have learned how to detect primitive shapes by using the Hough transform. We have also used OpenCV and Unity together to turn a pen and paper drawing into a physics toy. We have even surpassed the things that Q can make a pen do!
Still, a secret agent cannot solve all problems with ink and paper alone. Next, we will take off our reading glasses, put down our physics simulations, and consider ways of deconstructing real motion in the world around us. Prepare to look through the kaleidoscope of the frequency domain!
