Some image processing toolbox functions are available from within octave,
more with matcompat installed:

To see the values under the cursor interactively, you will need a separate
image viewing application which does it.  Then you will need a modified
image.m which calls that application.  Such a thing would not be too
difficult to write using GTK and Imlib but surely something exists already.
Alternatively you can use the same trick as gtext/ginput uses.  Instead
of returning the coordinates, though, it would just print the values of
at the matrix position.  ginput/gtext are both in matcompat.
