ofxCv::FlowFarneback

Using ofxCv::FlowFarneback how can i get the points where movement is created?

Looping for all the pixels in the input and checking agains the flow to see if there is movement in that pixel seems very slow so sure there is a better method

I agree with icloud you on the slow part. Its slow as molasses. Anyone with gimp help? much appreciated.

Brian.
