Subject: Can khoros be used to measure the total length of roots or thread-like objects?
Date: 6 Sep 92 16:27:44 GMT

I have never used khoros and I am trying to determine if I can use khoros to measure the length, area , and diameter of plant roots.  These root images contain root segments of various lengths and diameters.  Some are branched and some segments touch other segments.  My first priority is to determine the total length of roots in the image, although other information and the length of individual segments would also be useful.  Are there any routines or algorithms within khoros that would be useful for doing






 this?  So far I haven't been able to find anything in the amnuals, although I haven't printed all of them out.  I realize there are various processing algorithms that will be useful for manipulating the raw images, but I cna't find anything for measuring the objects within the image.  I realize I am a novice and I'm probably asking dumb questions, but it would be useful to know if it is possible before I invest more time.


Thank you for your help.

This is a follow-up to a post asking 2 questions.

1) Anybody have khoros experience with speech processing?

My answer is no. Sorry.

2) We are looking for the following tools (stuff) and advice.

My advice seemed relatively general so I thought I'd post what was going
to be my email reply.

I do signal processing with khoros, but find it less a ready to go application
as a tool builder. 

There has been some attempts to identify the signal 
processing faction and help each other. There is general recognition
that khoros has an image processing emphasis. I believe work is being
done to provide a very solid framework that will greatly benefit all.
Note that khoros is much more than the toolkits it supports.

My best advice is to get involved. Contribute effort, ideas, code, and/or
membership in the Consortium. I think the Consortium is probably the
most strategic (but I have been unsuccessful in convincing my management:-( )
The Consortium allows you various levels participation in the khoros project.
One of the great values of khoros is it can be made into what you want.

END ADVICE.

Actually, this advice is a bit much for someone seeking introductory
info. That's why I posted it. I hope the original poster finds useful
feedback.

Hello !

I have started using Khoros. I am working with satellite images
(Landsat/TM and SPOT and SAR). I have tried to use the K-means and
ISODATA routines. Has Khoros got other clustering routines for
remote sensing? Could any suggest some parameter settings for 
classification (clustering) using 3 or 7 bands (I thought the 
running of the routines itself took a very long time on our HP 9000/730!!).
Finally, is it possible to do a trained classification (clustering?)

Thank you.

Hi everybody,

we have successfully installed khoros on one of our DECstation 3100,
but we have in some cases performance problems with the system,
especially with xprism3.

Since we have at present only 12 MB RAM, we think the extreme performace
decrease is due to continous swapping. Is that true ? If this is the case,
how many RAM is recommanded to run i.e. xprism3 and other memory-hungry
programs without continous swapping ?

Also, we cannot get the animate program working and the shared memory
transport mechanisms always leads to core dumps.

Any help is gratefully acknowledged,

Khoros PL1.5 binaries for ISC UNIX on a 486 are available on pprg.eece.unm.edu.
They are in the main distribution area. A README can also be found there
describing the compilation and OS environment.

It seems to generally work OK at this time - we are getting more experience

hi to all the Khoros-Users out there!
 
we have a little problem:
 
a science group in Kopenhagen (danmark) is about to start
using Khoros. there hardware is a HP-9000/Modell 835.
                                 ~~~~~~~~~~~~~~~^^^^^
because they are no computer freaks, they like to
get a "ready-to-use" khoros-version.
(translation: they do NOT want to compile the Source.)

so my question:

is there a User-Group out there with the same hardware-platform, 
that can allow them to get there runnig version via ftp ?

i think they will need it in a view weeks.
can someone - with that platform - mail me the amount
of disk-space, they will need ?
 
ANY help would be fine!                    have a nice day ...

We are shooting for a November Alpha release of the core toolkits of Khoros

someday we need to put out a note about the new members!!!).

A Beta will follow in about 3 months that adds functionality to the core
and begins to bring some of the toolboxes on line.  And then about
3 months after that we want to put out an open distribution.  So, to answer
your question ..... we are very tentatively, no promises, shooting for
a May release.  We typically don't slip deadlines more than a few months so
depending on the weather and the price of coffee, we should put out Khoros
by early summer.   (I am beginning to sound like a politician, i.e. sound like

Subject: Re: vspeckle  (bug and suggested fix by Michael Bruce)
Date: 10 Sep 92 00:50:13 GMT



Subject: Crimmin's algorithm (lvspeckle.c) bug

There is a pointer indexing bug in the speckle reduction routine,
lvspeckle.c.  To verify the bug, run four iterations on the airport
scene (by the way, the airport scene in not Willow Run Airport in
Michigan; it is in fact Windsor Airport in Windsor, Ontario CANADA).
Looking at the speckle reduced image, you'll see a region along
the edges of the image and more noticably along the main diagonal
(lower left to upper right) which has not been processed.  The fix
is as follows:

        Under the POSITIVE HULL PROCEDURE, for each of the double
        FOR loop sections, the pointers must be incremented twice.
        That is,

                ...   }                 ! First FOR loop section
                      fmn_p++;
                      gmn_p++;
                      fab_p++;
                   }

        should be

                ...   }
                      fmn_p++;
                      fmn_p++;
                      gmn_p++;
                      gmn_p++;
                      fab_p++;
                      fab_p++;
                   }



        Likewise, the second FOR loop section requires double increments.


                ...   }
                      fmn_p++;
                      gmn_p++;
                      gab_p++;
                      gba_p++;
                   }

        should be

                ...   }
                      fmn_p++;
                      fmn_p++;
                      gmn_p++;
                      gmn_p++;
                      gab_p++;
                      gab_p++;
                      gba_p++;
                      gba_p++;
                   }


        The IDENTICAL modifications are required for the NEGATIVE HULL
        PROCEDURE.


There is also another (minor) error in the POSITIVE HULL PROCEDURE.
Inside the second FOR loop the code currently reads:

                ...   tmp = *fmn_p++;   /* this is the middle pixel */
                      if ((*fab_p) < (tmp + 1)) {
                         temp1 = (*fab_p);
                      }




I've made these changes and reincorporated them into my version of Khoros
and it now works.

I am well aware of the effect (or lack thereof) that zero-padding has

I think that these parameters are actually intended to tell you if
the entire viff was a subimage.  These numbers will tell you the starting 
position in the image that the viff was taken from, so you know where
to reinsert it.  If the numbers were negative, the viff was not a
subimage.

Subject: Expanding an image in only one direction
Date: 9 Sep 92 15:08:38 GMT

Hi,
Is there a way to expand an image in khoros in just one direction by using
pixel replication? Subroutine vexpand allows me to do this but in both 
directions simultaneously. vresize magnifies in either direction BUT using 
bilinear interpolation. I wouldn't like to expand the image outside khoros
and use khoros to display it; it would take too much space even if later
saved in compressed viff. 

This operation I want seems basic enough that it would be nice to have it
if not there already.

Thanks in advance for any help,

I am currently evaluating KHOROS for
signal processing and speech processing
applications.  Does anyone have any
experience in using KHOROS for speech
processing?

We are looking for a set of tools to
perform waveform editing, spectral
analysis, cepstrum, LPC, PARCOR, etc.

If you have any advice, please e-mail me on
r.prandolini@qut.edu.au

Kind regards
