Subject: cantata/Xwindow crashes
Date: 28 Jul 92 19:41:23 GMT


Hello Khorosters,

I am running SunOS 4.1.1 (unpatched ld) and Openwindows 2.0 on a Sun Sparc 2.

I have a 32 Mbyte processor and 128 Mbytes of swap space.  I have the number of processes set to 138 (of which I typically am using 50-65).  I am wondering if anyone else has the following problem:

At regular intervals the X server (xnews) hangs when I am running cantata.  I have to remotely kill the X server whenever this happens, logon again and rerun cantata.

Things that help are: 
  distribute the glyphs to another machine
  use smaller images
  stop background processes 
	(a remote user frequently runs a cpu-hogging program on my machine)

Since I eventually want to work with quite large images (1024x1024 at least), and since even with a cpu-hog running, my machine's still faster than the other one available to me I am eager to eliminate this problem.

Does anyone know what is causing this?  Will going to OpenWindows 3.0 help?

Thanks

Subject: Problem using TIFF2VIFF conversion routine
Date: 24 Jul 92 20:27:01 GMT

This is a repost of a previous, perhaps hard to read, querry:

 I have some images in TIFF format which I want to view and manipulate with
Khoros.  When I attempt to convert them to VIFF format, using tiff2viff, I get
the following:

} % tiff2viff -i egg_1.tif -o /usr/tmp/tiff2EAAa02200 -v 1
} egg_1.tif: Warning, TIFF directory is missing required "StripByteCounts"
field, calculating from imagelength.

} TIFFFillStrip: egg_1.tif: Read error at scanline -1.
} ltiff2viff: bad data read on line: 0 of TIFF image
} tiff2viff: ltiff2viff failed

As I have as little familiarity with TIFF format as I have with Khoros, the
solution is not obvious to me.  I am currently running an older patch level
of Khoros 1.0.  I'm not sure of the patch level, which in this instance may
not be relevent to the problem, but the files in KHOROS_HOME/release have
dates of early May, 1991.  How do I tell which patch level I'm at?
I'm using a SPARC2, running SUN OS 4.1.2.

Thank you for your help,

Hi, Gunnar:

I think we have part of the solution to your problem.  If you require the
user to designate the spots with the mouse,  you eliminate all of the
"a priori" uncertainty and greatly simplify the problem. My students have
written an interactive application  to track soils grains through sequences
of images.  The user clicks on all the desired gains with the mouse, and
the program segments the grains from the background.  The grain sil-
houettes are then passed to a tracking routine.

If you are willing to do some re-programming,  you could start with 
our program and change the back end,  sending segmented images to
vlabel and vshape.

If you would like a copy of our code, mail me.  Meanwhile,  maybe
someone has a better solution!

P.S.  I like the name of your machine.  My 10-year-old son ADORES
the Asterix books I brought from Europe last summer!

Khoros,

    I recently downloaded motion_blurr.tar.Z from the khoros toolbox directory
and have had problems trying to run it.  It seems just fine for a while, but a
certain point everything fails.  It ran on a RS-6000 with 32meg RAM and enough
tmp space, and I have also tried Sun SparcStaions, and a Sun 3/60 with no luck.
I get the same result every time.  I would like to know if there have been any
problems associated with this workspace previously and would appreciate any
assistance you could give.

Paraphrasing Q49 of the FAQ list:
We are trying to run cantata on a Sparc 2 running OS 4.1.1.
The program fails because of the following error:

X Error:  BadMatch
  Request Major code 62 ()
  Request Minor code 176
  ResourceID 0xb00105
  Error Serial #978
  Current Serial #983
Major X error encountered for display ':0.0'! Unable to recover.

Similar problems occur (fortunately less often) with xprism2 and 
xprism3 when run outside cantata. The error message is of the form:

 X Error:  BadMatch
  Request Major code 62 ()
  Request Minor code 0
  ResourceID 0xb005fb
  Error Serial #201967
  Current Serial #201994

Any ideas as to what might be causing these errors?

Also, we haven't been able to get a contour plot with 
xprism3 when the data are imported in ascii file format.
Any suggestions?

Subject: Use of band number vs image number to refer to separate images in files.
Date: 29 Jul 92 23:59:46 GMT

I have an image file created in our in-house file format (.sif) that is 256 rowsand 256 columns of short integer (2 bytes) data.  The file contains 72 images.  If I am going to convert this file to viff, should I create one viff file with 72 bands or 72 images or what?  It appears to me that in my limited experience with KHOROS that the image number field is not used, and that separate images are pretty much exclusively treated as separate bands.
Can someone clue me in one the appropriate useage of bands vs image number in
KHOROS? Is the image number field in the xvimage structure not currently used?
Thanks loads.

Some way or another, you have defined an expression called "KHOROS_HOME"
somewhere in your workspace .... I bet you accidently 'put' it with the
mouse into a string somewhere.  Anyway, one way to illimanate this
annoying expression is to edit the workspace file and delete the
line.   (if it is a compressed workspace, first uncompress it and then
edit it by searching for KHOROS_HOME)

It is possible for you to destroy the workspace file if you are not careful.

Perhaps you could create a Unix batch file or program that executes
your pipeline.  Then write a simple program that monitors the date
of the source image and calls your pipeline accordingly.  No need
to be running cantata.

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.

Even ideas on at least automating the above procedure would be useful.

I have a technical question about using khoros. Could you please pass this
on to whoever deals with such matters, or send me information on how such
matters are dealt with. Much Thanks. 


The question:

I installed khoros on a Sun IPX a few months ago, and am finally getting around
to using it. My main use is image processing within cantata. After I've built
up a data-flow path of six or so modules and started to push data through,
I get errors that the file system is full. I went to /usr/tmp and deleted
all the files associated with the early modules of the data-flow, leaving
only the one needed for the next step. I still get file system full. To
be more specific. The error occurs trying to perform any band pass operation
on an fft file. The original image was 512 x 512, (single band). What this
seems to say is there is not room for both the fft input to the frequency
filter module, and room for it's output as well. Is the only solution to
this sort of dilemma to re-configure the file system with a larger tmp
space? 

To extend the question slightly. I will want to have much more complicated
data-flow paths soon. Is there some general solution to this problem where
cantata manages old data files in such a way that I don't have to worry
about this, or keep bumping up tmp filespace to handle every new algorithm
I test / develop? Thanks for your help.

I don't use OpenWindows but can I suggest a look at $TMPDIR?
Our newsreader "xrn" and khoros both use this disk space and things will 
clag up if you run short of space. From the clues you give it seems
that's what's going on.
