Hello *! Who knows the author of the Fiji optical flow plugin 'Integral Block MSE’??? Must be someone who was (is?) at MPI-CBG… @ctrueden - you know for sure, right?
Followup question (the one I am really interested in): the outputs I get seem to make sense, but I wonder about the values I receive in the ‘flow vector’ image.
They do rouchly coincide even if I downscale the image by a factor of 2 in x and y direction… how comes?

Ok, ok, I guess I got it… the first channel (r) is in [0,1] and denotes the length of the flow vector relative to the block radius I’ve set in the setup dialog… at least this is my current hypothesis… :)
