openCV Optical Flow

May 15, 2012

Upon implementing this, I found that I could draw pictures with my nose. When I drew pictures in this way, my nose starting becoming ticklish. I think that this demonstrates that my sense of my body has really merged with the sense of a removed world created by the video.

This video demonstration was made using openCV and openframeworks. It uses the "Good Features to Track" corner detection algorithm as an input into a Lucas–Kanade optical flow detector.
