Dear Peter,
I did the upload via Nabble:
<
http://imagej.1557.x6.nabble.com/>
I'm not aware of a certain size limit, although there must be some
limitation.
=========================
Apart from this formal question, I should like to again point out that
the OP (Frank Shaffer) likes to characterize the *morphology* of jets in
*single* images. Originally he wrote:
"Attached is an image from a high-speed video showing turbulence eddies
of a submerged jet (UC Berkeley Fluid Dynamics Lab). We would like to
characterize the morphology (sizes, length scales, etc.)."
More recently Frank confirmed that he is interested in jet
characterization from single images:
"The feature recognition only needs to work on one image. Then it can be
repeated for the other images."
That said, I'm not sure if "Optical Flow" that is based on image
sequences, not single images, may help to characterize the jet morphology.
Regards
Herbie
