Re: External Viewer

[pcloetens]

Hello,
I was looking into using ImageJ as an external viewer for Octave and found
some discussions in the past on this topic. I wonder if something has been
done since then. Wayne proposed as solution to save the images with Octave
in a directory where ImageJ periodically looks for new files. This seems a
little restrictive. Probably you want faster display and also call ImageJ
commands from octave or vice versa; get some mouse clicking entries from
ImageJ into Octave, ... Isn't this rather something to be solved with
sockets.
Any suggestions would be welcome.

Hi there,

In my experience with Matlab, you need to write an interface class that starts
an instance of ImageJ.  I don't know how Java-friendly is Octave but Matlab is
quite Java-based (all the GUI stuff). I think going for RMI or SOAP will be an
overkill. ImageJ is not client-server oriented. And also - just forget about Java 1.x
Java 2 is THE standard.

best regards,

Dimiter

Hi!
An odd question. I work with tissue sections and sometimes I have to
zoom in digitally to get a good look at some microvasculature. When I
zoom in normally (my pictures are 8Mb TIFF files, 36 bit depth taken
with SPOT2 camera) I get rather quickly pixellation, loosing at the same
time some detail. I tried some deconvolution, gaussian smoothing and/or
unsharp mask, without a lot of success. What I need is not a labor
intensive (and admittedly more accurate) method to get rid of my pixels.
What I am looking for a what I have seen once on SGI where, while
zooming in, the pixels would "split" so that the apparent smoothness
would be preserved. This is especially important when printing such king
of photos.
So, is there a plugin (I could not find one) or a easy macro that would
help me with this problem?
