Hello everybody..

I'm working on a selection based on a plot profile (pixel values of a
line), where I want to detect luminance jumps and differentiate between
ascending and descending.

Here is an example..

Green: ascending marked
Red: descending marked

Is there anything I can start from directly available in imagej/fiji to
get these positions?

Thanks in advance..
Rainer
