Back in 2008 there was an amazing demo of realtime dense optical flow on a GPU[0] but all the links are dead now. I've searched hard for another comparable implementation since then but had no luck.
Does anyone have a hint on what technique they might have used?
Thomas Brox’s lab had a ton of these around 2008-2012 as well, such as [0]. I believe Brox had some freely available early CUDA program to calculate optical flow that was sort of SOTA for many years.
Hi @haxiomic, I'm the author of the article - thanks for reading! Several more recent approaches of computing optical flow with CNNs such as FlowNet2 (CVPR '17) (https://github.com/lmb-freiburg/flownet2) should also be runnable on video or live webcam feed.
