Subject: Generating a Series of Noisy Images
Date: 26 Aug 92 06:04:33 GMT

I am attempting to take a certain reference image and to create a series of
noisy images from it by adding gaussian noise to the basic image. I am using the
vggauss routine ,however I would like to know how I can get different noise
values from the routine. If I put the routine in a loop will it give me 
different output everytime I call the routine? If not, how can one create such
a stochastic process within Cantata?

I much appreciate your help.

	What patchlevel of Khoros do you have?  You can check in
	$KHOROS_HOME/src/PatchLevel and $KHOROS_HOME/repos/PatchLevel.
	$KHOROS_CONTRIB was replaced by toolboxes as of patchlevel 3, so
	this is your problem.  If you don't have patchlevel 5, I'd recommend
	getting it, since kraftsman, a program to help you create and manage
	a toolbox, wasn't completed until patch 5.  Once you have patchlevel
	5, just follow the directions in Volume 2, Chapter 1, to find out
	how to create a toolbox and install routines into it.

	Hope this helps.

Hello,

there is a problem with the new compress (Version 4.2.3, recently
posted in comp.sources.reviewed).

It has changed the semantic of the -c option. It now switches
always to decompress mode. This breaks cantatas way to store
compressed workspace and files.

If you want to install the new compress (its worth it as its amanzingly fast!!),
you should apply the following patch:

*** compress42.c.orig	Wed Sep  2 14:07:15 1992

You will need to change Form.c in $KHOROS_HOME/src/xvroutines/Lib/xvutils.
Try setting line 137:
	WidgetClass formWidgetClass = (WidgetClass)&formClassRec;
to
	static WidgetClass formWidgetClass = (WidgetClass)&formClassRec;

And in the file Label.c in $KHOROS_HOME/src/xvroutines/Lib/xvutils.
Try setting line 140:
	WidgetClass labelWidgetClass = (WidgetClass)&labelClassRec;
to
	static WidgetClass labelWidgetClass = (WidgetClass)&labelClassRec;

Recompile both of these libraries and then try executing cantata and editimage.

vggauss and all other random signal and image generators will generate
different output every time they are executed.  This is done by re-seeding
the random number generator with a function of the current time in seconds
and the process id for the process that calls any of the random number
generators.

However, prior to patch level 5, it was possible to get the same sequence
from two different processes if they were executed with one second of
each other.  If you are not at patch level 5, it is worth your time
and effort to update.

try the generic command glyph under program utilities.  If you pass in

If you turn on "Echo Execution" in Workspace/Attributes, this is an example
of what you would see echoed to your startup window.

2) It is impossible to abort an operation gracefully.

Are these problems being addressed?

Hi

I think the answer to your question is as follows:

Assuming that your image is stored in an image structure

struct xvimage *img;

then the Xsize can be obtained by looking at
	Xsize=img->row_size;
	Ysize=img->col_size;

I hope that this is of help

Khoros users,



We develop embedded signal and image analysis systems.  We would like to find
an image/signal processing tool with graphical user interface AND easy-to-use
code generation capability.  Thus, the algorithm developers could work within
a network-definition environment, and still on demand give  the software
developers a 'black box' algortihm in ANSI C, with known inputs and outputs.
Obviously the contents of the box would be highly inefficient, but for the
prototyping phases of a project they would be adequate.  Anybody out there
got cantata set up to do this?  Or used this capability from any other package?

Please respond directly to -- bruce@ektron.kodak.com --, as "reply" will
not work.


Thanks in advance,

K. Konstantinides suggests using xv to convert gif to tiff then using
tiff2vif to get viff format.  Although this will work, it requires that you
bring up a window containing the picture, and can not be done easily from the
command line.  May I suggest obtaining the pbmplus package?  It contains
MANY command-line driven programs for converting/manipulating images.  It
complements Khoros nicely, and may be used in Cantata (using Program Utilities->
Generic Command).

After all that, I don't remember where to get it!  I'd suggest looking in
your favorite comp.sources.{x,misc} archive (ftp.uu.net, wuarchive.wustl.edu, etc).

Subject: cantata variables
Date: 1 Sep 92 13:40:51 GMT

Dear Khoros users,
 I have a question concerning the cantata workspace.
We have started using Khoros since about a month and combine it with
our old image processing system, which (as expected) works with
another file format.
 In this format (called Multi-Modul File) one or more images are kept in one
file. So I wrote a routine that picks out one image and converts
it into VIFF and another one which tells me how many pictures are
stored in the file. Now I am trying to convert a whole file into
VIFF using a loop in cantata.
 My problem is how to store the number of images in a variable,
which I can use as the upper limit in that loop.
 Does anybody have an idea to solve this or know a better way to
convert this format into VIFF?

 Thanks

We DEFINITELY will be using full-text indexes, so I guess we need a  UNIX

already have a VAX 9000). We also have a 6000 runing ULTRIX which I guess
we could use.

I would prefer that we buy new hardware for this project. Anyway thanks..

After a quite lengthy struggle with gopherd 1.02, culminating in my
finally submitting to actually reading the man page, I have managed to
get WAIS indexing working.  However, I was not able to do it by simply
placing the index.src file in the gopher directory as implied by the
man page.  Certainly gopherd was not smart enough to split it into the
WAIS description and a search engine, as stated in the man page.

My question is this -- should the software in fact be able to take a
.src file and go with it?  Or is it necessary to do as I did and make
a Link file of type 7 that points to the directory which actually contains
the index?  Even then, I had to create a symbolic link to the directory
containing the WAIS index database within my gopher directory.. giving
it a relative pathname with '..' did not work, even though I am using
the -c option with gopherd.

This seems to be either an error in my understanding (and perhaps the
documentation) or in the code itself.  I would appreciate some clarity
in this matter, for I am sorely confused.

Thanks folks,
  Jonathan

      Hi.  A few postings back someone posted an article complaining about
Date: Wed, 26 Aug 1992 17:38:03 GMT

A follow-up article said to recompile AFTER putting /ir and /ui in the right
spot and removing waisgopher.o and Wais*.o.  I tried this with no success.
If anyone has successfully compiled wais-8-b5 w/ gopherd 1.02 I would be
greatful in hearing from you.  Please send E-mail to gil@klaatu.umd.edu.
Thanks again.
