My understanding, based upon a discussion in another group, perhaps
comp.graphics, is that the C versions of NR are mechanically
translated from FORTRAN and that they leave something to be desired as
far as quality C code goes.  The general consensus is that there are
better references available.

1) Collect the frequent questions first.

2) Obvious short lines like addresses, references, etc. can be placed
   in a file NOW.  One can add to these over time.  They should not need
   discussion.

3) Set up news on a Unix system to have the system chronometer (cron)
   post automatically at some frequency (.crontab or /etc/crontab or
   /usr/lib/crontab).  Inevitabilty, you will get this wrong.  Adjust.
   Monthly is too short, weekly for the same file is too many, the problem is
   that news expires at different rates on different systems.  Current
   methodology is to spread a set of linked but different files at intervals.

4) Novices have a hard time reading files longer than 200 lines.  They have
   neither figured out how to search nor skip postings so they frequently
   page or scroll to the bottom to get to the next post.  Forget about
   Killfiles.  Too hard for many of them.  Non-unix based news/notes systems
   and gatewayed groups present even different problems.

5) Not every one has anonymous FTP.

6) If you are really lucky, set up a mail server daemon like netlib.

7) You will never satify everyone.  You will still always get noise and
   insipid arguments to discuss boring frequently asked questions get
   flame wars.

8) Try to protect yourself with disclaimers refraining for medical or
   legal questions, netiquette (e.g., GIFs to alt.binaries.pictures, etc.).

So long, and thanks for all the fish.

I am interested in this myself, however I would like to use motion blur
and defocus as a measure of image quality.  ANy papers on this subject?
In particular I am trying to automatically measure the quality of scanned
documents.  My Initial feeling is to look at spectral composition of 
portions of the text using a DCT...blurred images should be different than
non-blurred images, but this may be difficult to detect in frequency
domain.  Any ideas?

How about routines for :

	- Thinning
	- Connected component labeling
	- Logical operations (AND, OR, XOR, ...)
	- Adding "noise"
	- Rotation

On a related matter, I think it would be a good idea if, along with a FAQ

Subject: Datacube mailing - clarification
Organization: University of Chicago Computer Science
Distribution: sci.image.processing
Date: Wed, 29 Jul 1992 03:56:58 GMT

There seems to be a little confusion about what the datacube mailing
list is (who should be on it, who should not be on it, how to
subscribe, ...). Over the last few days I got flooded with mail
"please put me on the list" and a few hours later "please remove me from
the list". Obviously, who ever published the datacube mailing list
address forgot to say what it is all about. The following is a brief
discription to resolve this problem.

What or who is Datacube
=======================
Datacube is a company that produces a number of boards for real-time
vision and image processing applications (-> special purpose
hardware). They also provide a software package to develop
applications in C for their boards.

The Datacube mailing list
========================
In order to create a forum for discussions about Datacube hard- and
software Matthew Turk (MIT) set up a mailing list. Any
Datacube-oriented discussion is encouraged.  This list is not
affiliated at all with Datacube, Inc. -- both praise and gripes are
welcome! Last fall Matthew Turk passed the administrative matters
around the Datacube mailing list on to me, Mark Stricker (U of
Chicago). In the meantime there are close to 100 sites on the list.
Anyboy working or planning to work with Datacube equipment can
subscribe to the list by sending mail to:

    datacube-request@cs.uchicago.edu        (this ends up on my desk)

This is the address for administrative issues (add me, remove me from
the list, ...). Please do not use the address
datacube-list@cs.uchicago.edu for these purposes since mail to this
address gets un-moderated to everybody on the list.

The Datacube mailing list IS NOT a general image processing or signal
processing mailing list. So, if you don't intend to use any Datacube
equipment then the discussions on this list are irrelevant to you.

Not necessarily.  See

for a method that uses space-variant linear techniques to avoid ringing.
It's quite powerful and works well.

Subject: Filter Ranges for Enhancement, HELP!?!
Date: 27 Jul 92 10:01:16 +1200

Greetings,

when filtering with a standard Laplacian filter
	[ -1  -1  -1 ]
	[ -1   8  -1 ]
	[ -1  -1  -1 ]
and assuming the pixel values from 0..1 in intensity, the result of the 
operation can range from -8.0 to 8.0. What is the standard way of
mapping this result to a pixel range.

I have tried just diving by 8.0, and if negative ignore but this just gives
"black" images, I also tried /8.0 and the absolute, still it looks terrible.

I have a program for the PC, Improces which does a nice job.

Could anyone give me some tips??

thanks in advance

Subject: TIMWIN bug
Summary: New version of TIMWIN uploaded
Organization: Delft University of Technology
Date: Wed, 29 Jul 1992 18:57:17 GMT

We have detected an error in TIMWIN, which causes an UAE (or GPF in
 Win3.1). It happens when you run one of the convolution commands: 
filt, gaus, lapl or shrp.

A new version has been uploaded at 

ftp.cica.indiana.edu, in  pub/pc/win3/uploads 
                 (named timwin10.exe and timwin11.exe!)  and 
ph.tn.tudelft.nl, in pub/upload (timwin1.exe and timwin2.exe)

In this new version the bug has been removed, and some enhancements
have been added. If you want this new version, you'll have to
download both files (timwin1.exe and timwin2.exe) because old 
command files are not compatible with the new version. Thus, remove 
your old version entirely and install the new files from scratch.
If you want to stick with the old version, it's OK, but avoid using 
the mentioned commands. You can run the demo program without danger, 
since they are not used there.

Sorry for any inconvenience

You should be careful announcing this to the net. I would bet that the

In fact, a quick review of the flyleaf shows a notice that unlicensed

Hi all

I am stuck and need to know if there is any type of a device that will solve a
problem that I am working on.

The situation is that I have graphic scans (heart rate output over time) on 8-1/2
by 11 sheet of paper.  I need to translate these graphs into x and y coordinates
for the entire length of the graph.

I can manually, using a digitizing table and a cross-hair input device move along
the line and "click" each time I want to register a point.

What I need to know is there anyway that I can automate this process, because I
really need to obtain "continuous" points.

Is there some type of a "tracking device" that can be taught what a line is and
then follow the line as the chart is re-run through the machine that it was 
originally recorded on ??????  

Has anyone "mickey-moused" any eye-tracking devices to accomplish this ??


Any and all help will be appreciated.

I'd say that any attempt to simulate the actions of neurons in the brain in
the conventional sense (that is, by modeling the actions of the neurons _after_ 
figuring out what the neuron collectives _do_/what "properties" they have) will,
and must, fail.  Hoefstaedter makes claims in GEB for a theory of "jumping 
levels"; that is, analysing the behavior of the neuron networks at a higher/
simpler level, will allow an understanding of brain thorough enough to simulate
intellegence.  (the Aunt Hillary allegory). This approach seems like it could 
yield limited success -- limited by the depth of the model.
	The most likely place I've heard of -- the most likely research, that
is, is in Artificial Life research -- particularly that which deals with 
evolution simulation.  The functions of the brain are not "hardwired" or even 
predictable, (except in a general/macrostructural sense); the brain functions are 
adaptive and evolutionary.  
	I've got to get back to work -- I know this above has been said, just 
thought it'd be interesting to get some dialogue on chaotic evolutionary systems
and answers to modeling problems, etc..
