Excerpts from Robert Jobbagy's message of Sun Apr 22 14:59:22 +0200 2012:
I also made an "opticalflowfinder" element, part of my GstStabilizer project:
https://github.com/guijemont/GstStabilizerKeep in mind that it is code that has not been widely tested, and that the
element is written in python for GStreamer 0.10, and the format in which the
flow is transmitted is python-specific. In other words, it might or might not
help you, but if you want to, say, write an element that finds the optical flow
in C, that could be a source of inspiration.
I also wrote a blog article[1] explaining more stuff about that project, and
gave a talk[2] at the last GStreamer conference.
Worth considering also is the work by David Jordan, that made his own
implementation of a dense optical flow algorithm (Proesmans):
