Directional Motion Detection and Tracking using Webcam in TouchDesigner #touchdesigner #tutorial

You might be familiar with simple motion detection techniques in TouchDesigner using nothing but a webcam, but what if you also wanted some direction information? Using the Optical Flow and some CHOP processing we can get a relatively clean signal of the general direction of movement (Left/Right/Down/Up), for very cheap in all regards - no blob tracking or OpenCV needed. We can then use these signals to trigger things based on the general direction of motion in the input, or control motion based on these directions.
