about

This is my first contribution, if you have tips would be really worthy!

It contains Optical Flow solutions based on Horn and Schunck and Lucas and Kanade papers. I used them for my bachelor thesis, introducing intrinsic variations (5x5 kernel for derivatives or iterations in HS) and extrinsic (preprocessing and postprocessing) that increase the quality of the prediction. The results are given in RGB and vector representation.

hi! how is the rg texture accesible? OF texture looks black. thanks!

The rg texture is the output from the OpticalflowHS and OpticalflowLK, if you pre or postprocess it the colours will get softer, but should still be there. With a boost you should be able to visualize it. Tell me if it works!

to see the texture one must scale it up (e.g. by hscb texfx)
obv the original values are pretty subtle

joreg: Two #vvvv workshops this week in #berlin: Friday: Physical Computing, Saturday: Computer Vision. Tickets: upcoming-full-day-vvvv-gamma-workshops-in-berlin

~3d ago

joreg: @cznickesz also feel free to join our chat for such questions: chat

~3d ago

cznickesz: @joreg: Yeah, I´ll give it a try! Thx

~3d ago

joreg: @cznickesz: we're hoping this week. but depends on feedback. please test your project and let us know if it works.

~3d ago

cznickesz: @joreg: I should stop asking my questions so cryptic ;-) So right away: is final Beta39 hours, days or weeks away?

~3d ago

joreg: @cznickesz: the idea of an RC is exactly to make sure your projects will work with it. your last chance to report problems with b39.

~3d ago

cznickesz: So how "RC" is the "RC3"? I have to update an old project soon and I´m wondering if I should wait and directly update to Beta39

~4d ago

joreg: @takuma, the "one frame" issue was fixed in RC3 for beta39, see: beta39-release-candidate

~4d ago

Takuma: @joreg thank!! Ill try this. Are there a way to send video texture from vvvv to vl? fromimage node in vl somehow only sends 1 frame
