v002 Optical Flow is port of Andrew Bensons HS Flow implementation on the GPU.

Optical Flow allows realtime analysis of the motion within a series of frames of video. This determines the movement and direction vectors of pixels over time. Using optical flow allows you to use video as a ‘data source’ for image effects, allowing you to distort, displace, or blur images or video frames based motion in other video frames.

v002 Optical Flow consists of:

• v002 Optical Flow
  GPU based Horn-Schunke Optical Flow Implementation - ported with permission from Andrew Benson
• v002 Glitch Optical Flow Distort
  Image Distort via Optical Flow input - ported with permission from Andrew Benson
• v002 Glitch Optical Flow Blur
  Image Bluring via Optical Flow input
