Several weeks ago I mailed a request for information on the ISO
standards on image processing and interchange. I received three very
good mail replies. It seems that it is available in Europe, but I can
not find a US source. The lady at the ANSI ordering office could not
find the number. I am including the messages that I received, but I
am not passing on some of the email contacts that they gave me. I
will continue looking for a US source and send the information when I
find one. Any additional information will be greatly appreciated.

Its very fresh ! I just ordered the Draft from the following address:
Dr. Detlef Kroemker
Imaging Rapporteur
Fraunhofer AGD
Wilhelminenstr. 7
6100 Darmstadt
GERMANY
phone: +49-6151-155-140
FAX: +49-6151-155-199
The draft is in 3 parts and amounts to 1100 pages. They take DM 150,-
for there copying costs.
I talked to the secretary of Dr. Kroemker about your posting. She tolds me
that you could connect her directly by telephone to discuss details about
delivery abroad.
Some weeks ago I discussed with Dr. Kroemker the issue whether it is possible
to make the Draft available on a ftpserver. He said that there are principal
problems because organizations like IEEE earn money by selling printed versions
of standards.
If you see a possibility to make the standards available online I would be
very interested in.
Good Luck,
Arnold

The ISO standards are the Programmer's Imaging Kernel System. They
are currently being reviewed in the US by ANSI committee X3H3.8, the
next meeting of which is being held in Lowell, MA, August 10-12. I
don't know if the document is available publicly yet. The only
public reference I have to this work is

Dear Tom,
responding to your question in sci.image.processing:
the committee drafts of all three parts of the IPI standard,
namely the Common Architecture for Imaging (CAI), the
Programmer's Imaging Kernel System (PIKS) and the Image
Interchange Facility (IIF) are available since May 1992.
The official ISO numbers are 12087-1, 12087-2, and 12087,
respectively.
Usually, standards documents can be obtained by the
national standardization bodies which is the ANSI in
your case.
Best regards,

Speaking as one of the document editors of this standard, let me say a few words which I hope will be representative of the imaging group as a whole. We (the imaging group) are keen for information on the standard to be disseminated as widely as possible, and that could include, for example, making the documents available in machine-readable form, probably as PostScript. We are certainly discussing the matter. However, we are somewhat constrained in this by the rules under which ISO operate. For example, when documents reach draft international standard stage, ISO owns the copyright and electronic (=> free) distribution to the `general public' (i.e., anyone not involved in the national or international standardization process) may be prohibited: the sale of standards documents helps finance most national standards bodies. A few comments on things people have said: > The ISO standards are the Programmer's Imaging Kernel System. No. PIKS is only one part of "Image Processing and Interchange", the other -- and equally important -- part being the "Image Interchange Format". However, measured in pages, PIKS wins, with 850 vs 113! > They > are currently being reviewed in the US by ANSI committee X3H3.8, the > next meeting of which is being held in Lowell, MA, August 10-12. It is also being reviewed by all other ISO `P' members. A vote on the Committee Draft documents will complete on 4th Sept, and the next ISO imaging meeting will be in October in Germany. Another draft should follow that meeting -- but whether it will be a second Committee Draft or a Draft International Standard depends on national bodies' comments. > The only public reference I have to this work is... There are papers by all three document editors in Proc SPIE vol 1659. I also wrote a short status report which I posted to comp.graphics some months ago: if anyone would like a copy, please contact me (I shan't post it unless I'm overwhelmed with requests). For interested parties, there will be a one-day introduction to IPI at the Eurographics conference in Cambridge (UK) in early September. I'm too modest to say who will be giving it. I shall try to negotiate with Eurographics to let me make the notes publically available. Please feel free to contact me if you have any questions (or post them to the newsgroup: I guess there are other people who are interested). -- Dr Adrian F.

Hello, I am currently working on a program to rotate a bitmap image using the very simple transformation alogorithm. However, after compiling my C program, I discovered that it takes 2 minutes to rotate a 64x64 image!!! I figure later that the main reason for the slow performance of my program is due to the fact that I am using simple sine and cosine functions to manipulate floating point numbers...that is why it took so long. If there is anyone out there who can offer me some suggestions to getting my program run faster...please email me. I am currently using Microsoft C ver 7.00 compiler and 386 machine. Thanx! ** Chris **

I just read the Draft and I am really enthusiastic about it. It defines in Detail a complete state of the art image processing package. And it is very clear and concise (the majority of the 1100 pages are due to operator definitions). Every operator is well defined on several pages following a general scheme. The functional description is so complete that you literally can take the Draft and start implementing it. Even a complete set of error messages is defined. The development of the IPI standard has been assigned to ISO/IEC JTC1/SC24/WG1/Imaging Rapporteur Group The group just released the ISO/IEC Committee Draft (CD) 12 087. The IS Text is expected June 1994. The IPI Standard (functionally description) initially contains three parts: 1: A Common Architecture for Imaging (CAI) Editor: Dr. Adrian F. Clark 2: The Programmers Imaging Kernel System (IPI-PIKS) Editor: Dr. William K. Pratt 3: Image Interchange Facility (IPI-IIF) Editor: Georg Rainer Hofmann The Draft amounts to 1100 pages. API Language bindings are under development. --- Dipl.-Ing.
