Me being a human Mograph Effector. Uses optical flow from openCV to capture the pixel movement. I've added a little particle system on the end which blends the position back to it's original over time.
I've brought in some optical flow data from a live camera feed and represented it in the viewport. This is stage one, getting the data in, next stage is interactive realtime prototyping for testing interactions.

AR Drone Target Tracking with OpenCV - Optical Flow - This work have been made during 2012 summer internship at Winlab, Rutgers (NJ). I use the cvCalcOpticalFlowPyrLK function from OpenCV to find the optical flow in the live video stream from the Ar Drone.
