Subject: Image File Formats
I know that there are a lot of image file formats around. Does anyone
know any paper, report, text book, etc., mentioning the details for
the different image file formats?
Alternatively, you can send the description of particular formats. I'll
summarise and send results if requested.
Thanks in advance

Subject: Digitized Mecial Images
Wanted:
Digitized medical images(including phantoms) from CT,
SPECT, MRI or any other medical imaging source. I have
tried to obtain the images directly from hospital and
institutional sources but have been refused, on
confidentiality grounds. If anyone knows where I might
get these images(ftp sites, etc.) I would truly
appreciate it. I am attempting to do a medical imaging
project but cannot proceed without test material.
Thanks in advance!!
Please mail responses to :
brian3@garfield.cs.mun.ca
[ A few of these images would also be very useful for the Vision List
Archive. Especially if the imaging parameters accompany the data.
Please contact me if you have this data.

Since you know the reason for the "ringing" (diffraction from an edge)
why not deconvolve the image with the appropriate kernel (sinc(x))
which should provide an image without ringing and nearly ideally
recover the original object. Then use conventional linear estimators
for the edge location to sub-pixel precision.
Be careful since sub-pixel precision trades off gray level for
resolution so you need to be careful with your lighting.

netters,
i'm looking for references to discrete relaxation, especially (though
not necessarily) as applied to the problem of image segmentation. i'm
aware of rosenfeld & kak's use of it in, "digital picture processing",
but i'm looking for additional sources.

Subject: 3-D manipulation programs needed!!!
I need computer code (in FORTRAN or PASCAL) to do the following:
1) Generate random 3-D objects.
2) Given a 3-D object and a view point to determine a 2-D
projection of the 3-D object (with hidden lines not
being visible).
3) Given two graphs to determine whether the first graph is
a subgraph of the second
Any help on the previous problems (in terms of computer code or
references) is highly needed and any assistance is appreciated.
Thank you in advance

Hello:
Is anyone aware of software packages for image restoration? I am
specifically looking for robust routines (preferrably in C) that can
deconvolve a point spread function from a *noisy* gray level image.
Thanks!

IMAGE PROCESSING - IMPLEMENTATIONS AND SYSTEMS
Part of the SPIE/IS&T Symposium on Electronic Imaging: Science and Technology
9-14 February 1992 * San Jose, California
Conference Chairs: Ronald B. Arps, IBM Almaden Research Center;
William K. Pratt, Sun Microsystems, Inc.
Cochairs: Myron D. Flickner, IBM Almaden Research Center;
Robert M. Haralick, University of Washington
Important dates:
Abstracts due: July 15, 1991
Author notification of acceptance: November 15, 1991
Camera Ready Abstract Due: December 2, 1991
Manuscript due: January 13, 1991
During the past few years there have emerged two important trends in
the implementation of image processing systems. First, is the
creation of a new generation of image processing chips, which offer an
astonishing degree of capability in small packages at relatively low
cost. Second, is the development of standards for image processing
and interchange. These implementation trends are likely to profoundly
affect the design of the next generation of image processing systems.
This conference will seek to cover both hardware and software. In
the hardware area, surveys will be given on the capabilities and
functionalities of programmable and fixed function, VLSI image
processing chips that have recently been introduced. The theme of
this area will be exploration of how the availability of such chips
will affect the design of future image processing systems. In the
software area, surveys will be presented on the emerging dejure software
standards being developed by the International Standards Organization
and the X Consortium, as well as defacto standards such as TIFF for
image transport. The theme of this area will be how these software
standards will affect the design of image processing systems, with
emphasis on the development of associated software development tools
and graphical user interfaces.
The conference will bring together individuals who are concerned with
the implementation of image processing and interchange systems from
both hardware and software perspectives. Papers are solicited on the
following and related topics:
* programmable and fixed function image processing and interchange chips
* image processing hardware architectures and systems
* image processing and interchange standards
* image processing software architectures and systems
* image processing software tools and utilities (including compilers,
graphical user interfaces, and image data base systems)
