Hello,
	I have sent a question regarding the implementation of spatial analysis.
Dr. Donohue replied. Now I understand that spatial analysis is not implemented
in co-occurrence matrix. However, can you please provide me with the 
complete algorithm of spatial analysis, especially the CONTRAST option? Thank
you. Regards.

	No, you can use a different directory than /usr/tmp.  All you need to
	do is set the environment variable TMPDIR to a directory on a disk
	that has more disk space.  To set it to a directory called temp in
	your account, you would type:

	% setenv TMPDIR ~brent/temp

	If you do this, cantata will use the pathname in TMPDIR as the directory
	it will use for temporary storage, rather than /usr/tmp.

	Hope this helps.

Hi

First an apology for mailing my request to be added to the list to this address.

I have just started using Khoros and would like to be able to display 16bit 
grey-level images.  If I understand the manual correctly this is not possible
using the available viewers.

Does anyone have or know of a viewer that would allow me to be able to view these
images.  Ideally what I would like is something that would allow me to choose
a range of the grey scale to look at at anyone time and that would also allow
me to look at the whole range and automatically scale down to 8 bits.  The
SUNVISION package will allow me to do this but does not have the capabilities
and expandibility of Khoros.

Any help would be appreciated.

Thanks

Subject: triggering Cantata
Date: 29 Jul 92 13:44:01 GMT

I am acquiring images using a PC (under DOS -- ARGH!) linked to our
Sun network.  Using PC-NFS, the images are saved directly to the Sun
server.  Unfortunately, due to the nature of our images, it is not
possible to determine whether data is "good" without some processing,
which we use Cantata (running on a SparcStation) to perform.

What I would like to do...

Since our PC software has a "live" collection mode for focusing, etc,
and since an X-terminal sits next to the PC, I would like to specify a
file name to the PC software which would be re-written every few
seconds or few minutes, and trigger a Cantata pipe-line whenever the
source image is updated (by watching the creation date, or something)
to process and display the new acquisition.  Although I have written
several vroutines, I don't know enough about how Cantata schedules
execution to know how to do this.  What would seem appropriate to me
would be a vroutine that would cat the raw data file to its output
every time the creation time changes.

Does anyone have suggestions or a place in the manuals to look?  Can
Cantata be coerced to do this directly?  Thanks.

Hi,

I have a question and hope you guys can help me out. I am working on
Sparc 2 24bit display workstaion. I have a 24 bit image which I
display using Khoros editimage utility. This image was created by
combing red,green,blue (8 bit) images and combining them to a sigle
24 bit image (using vbandcomb utility).

But when I print pix values option in all three bands same pixel
values are appearing. The question is 
(a)  How can I tell if vbandcomb
     is generating a single 24-bit image ?
(b)  If it is a 24-bit image why print pix value option in the
     editimage is showing the same pix values for all three bands.

Thanking in advance.

hi to all the KHOROS-User,
 
do you remember a diskussion about 2 month ago about a
tool that lets you "simply" edit some pixels inside an image ?

that time i was looking for a tool with well known 
functions like fill, box, paint, brush, line, spray  etc.
              --------------------------------------
running under X11.

know where IS a tool:

               XPAINT 2.0 (beta 2).
              ---------------------
it works on XBitMaps and PBMPLUS-Images with up to 256 
colors/grey-levels.

so you can edit KHOROS-Images by VIFF2PBM them,
XPAINT them and then PBM2VIFF them back.

i have tested it under Ultrix 4.2.
beware: it is a Beta2-Version, but it works nice for me.

if you like to get it, it is in UseNet's alt.sources and
on our ftp-server bilbo.imsd.rwth-aachen.de (ip 134.130.12.5).

Raj,  I think that vlabel should do the trick for you,  unless the 
images are very noisy or have poor contrast.  Perhaps you need to
clean up the images,  or experiment with the control paramters.  I 
think the author of vlabel (now living in Paris) is on vacation;  maybe 
when he gets back he'll have some better advice.

Cantata won't let me use cache instead of temp files and I assume it is because

     I am trying to use Carla's recipe to create my own

Sorry for my tardiness. This response is hardly authoritative, but we K users
should offload the K group as much as possible. 

The issue here seems to be the change of emphasis from Makefiles to Imakefiles
and the supporting configuration files.

I recommend creating a toolbox for playing. Use Kraftsman, the tutorial, and
Vol II.

Call the toolbox, and its root
directory, 'TB'. In this setting, the best place to indicate 
the location of your in-house 
lib is TB/repos/config/imak_conf/TB.def. This is a file of TB specific
imake definitions. My personal touches to one of my toolbox def files,
'tools.def' is as follows (just the diffs):

***************************************
    /* Set library loading search path.You should not have
     * to change this symbol.
     * The default is toolbox_home/LIBDIR.
     * Note, /usr/lib and $KHOROS_HOME/lib will automatically be searched.
     * You do not have to specify these.

    /* List all FORTRAN libraries created (by you) in the toolbox.
     * follow the same concept for listing the libraries as described
     * for the TOOLBOX_LIBRARIES and TOOLBOX_DEP_LIBRARIES above.
     */

    FOR_TOOLBOX_LIBRARIES = -lapack -lblas
    FOR_TOOLBOX_DEP_LIBRARIES = /**/
******************************************************

I don't fully understand imake, but I have it set up enough for it to
be really valuable, pursue it!

Note that my libs are Fortran libs. Other libs (C) go somewhere else.
I'm afraid I don't grok the numerous imake variables.

Also note that if these ideas are implemented in an existing toolbox, DELETE
the Imakefile and Makefile. When you invoke imkmf ("oh great gods of imake..")
USE the -toolbox and -type flags.

Sincere efforts to help should always be reviewed by experts. Either that or
hit RETURN.

Good Luck!!!

The spatial analysis routines in "vspatial" do not use co-occurrence
matrix methods.  vspatial just computes the sample mean, variance,
entropy, etc.,  over overlapping regions or "superpixels" in the
image.  All the spatial measurements computed by vspatial can be
derived from the grey level histogram.

The quickest way to do this in Cantata is unsharp masking.  You smooth
the image with any smoothing filter -- the median filter does the 
least damage to edges.  Then scale the smoothed portion and subtract
the scaled,  smoothed image from the original.  Finally, rescale the
result for display,  using vconvert or the histogram stretch.  Use
a fairly large window for the smoothing filter -- I sometimes use
one as large as 31 pixels.

Subject: Suggestions wanted
Date: 28 Jul 92 09:10:49 GMT


I am trying to develop a workspace for the interactive(!) measurement of areas on
electron microscope 8bit pictures (Grayscale). The areas to be measured should be
circular dark gray spots. 
 An automatic measurement using a simple threshold algorithm in order to get a 
binary picture which then could be measured by vlabel and vshape would not give
an correct result, because the histogram of these pictures is (in most cases)
not bimodal (No separate maxima for background and dark-gray-spots).
 
After the measurement of the areas (or some other size-proportional property like 
circumference, diameter etc...) the results should be composed to give a histogram
of the size distribution of the objects. Also I would like to preselect the objects
to be measured (Some objects may be too small or too large).

The approach would be something like:

  1. Select spots interactively by clicking on all spots to be measured using an 
     application like Warpimage (source input only).

  2. Fill the spots using an algorithm which determines the border of the object.
     Any suggestion as to the nature of such an algorithm would be appreciated.

  3. Label the resulting binary image using vlabel.

  4. Measure the resulting label-image using vshape.

  5. Extract the area-information and plot a histogram of area distribution


I would like to know if this or part of it has already been done by another user. 
Especially I could need some advice on point 2. 

Thanks,
