Hi Yang,
of course, ImageJ has the image data in memory, but it does
not have a "hidden" window with the data as text.
What one could do is writing a plugin that shows the pixel
values of the immediate surrounding of the current pixel,
e.g. 5x5 pixels around the cursor. An alternative (or extension)
would be writing a plugin that writes these pixel values to
the Results table. Would that solve your problem?
Having a table of ALL image data would be a challange at least
for slower computers and big images - I don't think that this
would be useful.
I am not aware of an existing plugin that could do this; maybe
someone else knows a suitable plugin.
Doing math with ImageJ should not be a problem (Process>Math,
Process>Image Calculator, Analyze>Measure); operations except
ImageCalculator support selections.
Michael
