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

Ooh, you are getting fancy with dmg’s and aliases and everything :o) Awesome, great work, and I love your new install setup, it looks slick. Best regards, as always…
man oh man. exciting.
I think my pants are melting. Wait, that’s just fluid flow…
beautiful work!
These don’t seem to be working in Snow Leopard unless i’m doing something stupid?
Correct, I need to update them 🙂
wicked… would love to test this on snow leopard!

beutifull. thank you.
nice patch!
but i have a problem, when i use any CIfilter in the output the blue color component gets lost (it’s zero), here is an example with blur

am i doing something wrong?
Hi Vade,
Thanks a lot for sharing these great effects!
I’ve download v002 Optical Flow, and try to put it to VDMX as an effect but seems invalid.
i am using a 10.6 Snow Leopard/ Quartz 4.0, any advise if you please?
