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!

@prince cannot confirm

spot on!

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

joreg: also there is this nuget which sounds like an option: https://www.nuget.org/packages/TidyNetstandard/

joreg: if basic format tyding is enough you can use the XML ToString in VL

mediadog: Thanks @joreg. I really miss Tidy (XML), use it to clean up weather station data for realtime displays, any recommendations?

joreg: @mediadog thanks for the pointer. fixed.

everyoneishappy: @overtones this would require 4D noise, which is possible but not implemented in Fieldtrip

overtones: Hi! SF2D has Time & DomainOffset inputs, but SF3D only DomainOffset. Is there a way to use Time in SF3D or it makes no sense? Thx

joreg: @SabrinaVerhage this could be useful for you next "hacking sex" workshop: https://buttplug.io they have a .NET nuget for use in vvvv!
