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

ravazquez: @karistouf you can use my Global S&R contribution for this purpose

joreg: yes, no S/R. OSC is one way to communicate btw. instnces.

karistouf: @joreg: between 2 differents instances of VVVV on same computer,no S and R (values) possible ? only OSC way ?
