Subject: Do you have an anonymous ftp archive of imagery for public use?
As a service to the readership, it would be nice to have a list of sites
that maintain anonymous ftp sites with imagery. If you maintain such
a site, please let me know. I will compile a list and place it in
the Vision List Archive for general reference.
thank you,

Subject: NSF vision workshop report available in Vision List Archive
A 1.5-day NSF-sponsored workshop entitled ``Challenges in Computer Vision:
Future Research Directions'' was held in June 1991 immediately after CVPR '91.
This workshop was the subject of a panel session at CVPR '92, which was held in
Champaign, Illinois in mid-June, and a compact version of the workshop report
appears in the CVPR '92 proceedings on pages 189-199.
Shahriar Negahdaripour and Anil Jain (the workshop chairs) have requested
that the full text of the final report be made available over the Internet,
and Phil Kahn and I will each maintain copies of the report for retrieval
via ftp.
The locations for the files are
ftp.ads.com:/pub/VISION-LIST-ARCHIVE/DOCUMENTS/NSF-FDCV-report/*
gecko.eecs.wsu.edu:/pub/NSF-FDCV-workshop-report/*
In the .../NSF-FDCV-workshop-report directory, you will find four
files:
1. a README file
2. body.ps (56 printed pages): the body of the report.
3. app1+2+3.ps (5 printed pages): the attendee list, agenda, and group
session membership lists.
4. app4.ps (92 printed pages): responses of the attendees to a questionnaire
on the current state of computer vision research. These responses were
gathered prior to the meeting.
Cheers,
Pat Flynn

Subject: image processing book - summary
=> seeking a Book on Image Processing Routines
A summary of the answers:
1) Davies, E.R., "Machine Vision: Theory, Algorithms, Practicalities"
Academic Press, London 1990 (ISBN:0-12-206090-3)
2) Pavlidis, T., " Algorithms for Graphics and Image Procesing"
W H Freeman ISBN 0-7167-8106-9.
Unfortunately, those were the only two books recommended so far. The first
one I have not seen yet, because I could not find it.
I was really looking for a book in the same style of the "Numerical
Recepies, by Press" and in this sense the Pavlidis book just gives the basic
idea behind some simple algorithms, and does not cover basic algorithms like
filtering, histogram equlization, border detectors...
Some of those routines are better explained for parallel implementation
in:
Digital Image Processing
pratical applications of parallel processing techiniques
by Zahid Hussain
Elis Harwood Publ., 1991
ISBN 0-13-213273-7 or
0-13-213281-8 pbk
which I found to have the most recent concepts in Image Processing all
togheter compiled in a easy way even for the beginers.
Anyway I must say that I still looking for the book but meanwhile I've
implemented some of these routines by myself coding in C under X Windows.
Thanks to all colaborators.

Subject: Seek color constancy data
I would like to obtain color constancy data (in the form of
input and output association) similar to that used by
Poggio et al in NIPS for training neural networks. Any suggestion and
information will be appreciated.

Subject: Looking for elliptical arc fitting routine
G'Day
I am looking for a stand-alone routine (ie that does not use NAG
or Numerical Recipes) for fitting an elliptical arc to a set of
connected points, hopefully with some indication of the errors.
If anyone has such a routine in C, Pascal, or Fortran I would be
most grateful for a copy. Please note that the code, in some form,
will be integrated into the ORT package for public distribution.
I will fully reference the author unless otherwise indicated.
Thanks in advance.

Subject: Looking for graph digitiser
G'Day
We have some scanned images of graphs that we would like to digitize.
These images are scanned from the output of drum pen plotters attached
to ground magnetometers at Russian observatories. Some major problems are:
1. The images are noisy
2. The plots themselves were on pretty old paper which
was moderately dirty
3. Some plots are white on black, and others black on white
4. There are grids and labelled axes associated with each plot
5. The thickness and colour of the plotted lines varies
6. The plots are not co-axial with the image
I have looked at Flexi-Graph which is a commercial application for Macs.
However this is more suited to individual cases rather than batch processing
hundreds of plots. What I would really like is some source code in C or
Fortran, for Sun, Decstations or 386/486 PCs that I can modify. Any help,
advice, or pointers to other applications is most appreciated.
This problem also seems like an excellent vision project for anyone
interested, so any suggestions for joint projects are most welcome. I will be
going to Moscow on the 25th of July, to collect more plots, so setting up a
joint project with colleagues in Moscow (IKI Space Research Institute) is also
possible.

Part of 1993 SPIE/SPSE Symposium on Electronic Imaging
January 31 - February 5, 1993, San Jose, California, USA
The large variety of imaging modalities for exploration of objects
of biomedical interest has led to the necessity for solving many problems
related to the specific characteristics of the radiation and sensing apparatus
used. Acquired biomedical images typically suffer from degradation related
to the physical limitations of the imaging device. These degradations serve to
complicate the generic goals of analysis and interpretation. This conference
is devoted to the presentation of new techniques directed towards the improved
interpretation (interactive or automated) of biomedical images obtained from
practical systems. Papers are solicited which detail methods for reconstructing
images from partial information, for correcting image defects, or for
effectively extracting/analyzing/interpreting practical images of biomedical
interest.
Papers are invited in the following and related areas:
Biomedical Image Processing
- Image Reconstruction
- Image Restoration and Enhancement
- Feature Enhancement and Extraction in Biomedical Images
- Biomedical Image Analysis and Interpretation
- Multi-Dimensional Biomedical Image Processing
- Motion Analysis in Biomedical Images
- Multi-Modality Imaging
- Microscopy Imaging
- Knowledge-Based Methods

On Human Perception of Regular Repetitive Textures
Leonard G. C. Hamey

len@mpce.mq.edu.au
May 26, 1992
ABSTRACT
Regular repetitive textures occur frequently in both natural and man-made
scenes. The human visual system is highly effective at extracting the texture
element and structure of such textures. Surprisingly, even when presented with
random repetitive textures, human observers are able to immediately identify
the repetitive nature of the texture and to describe a perceived structural
unit. This paper presents a qualitative exploration of some of the
capabilities of the human visual system in relation to the perception of
regular repetitive textures. In particular, some limitations of the
perception of regularity are demonstrated. I hypothesize that the perception
of regularity is mediated by perceptual organisation of dominant primitive
features or dominant meta-features (perceptual groupings of features). This
hypothesis suggests that the perception of regular structure can be prevented
by either suppressing the extraction of the primitive features, or by
suppressing the dominance of a single feature or meta-feature. The suppression
of feature extraction is difficult, and results obtained to date are only
partially successful. The suppression of dominance, on the other hand, has
already been achieved in commercial textile design. The surprising result
of this paper is that the suppression of dominance can be effectively achieved
by arranging only four pattern units in the texture element in such a way as
to create competing perceptual groupings between the pattern units. The
resulting four-dot texture produces the visual impression of a field of
dots rather than a regular repetitive pattern. Modifications to the pattern
that create a dominant primitive feature or dominant meta-features are shown
to mediate the perception of regularity. It is expected that these patterns
will aid in developing an understanding of the processes underlying human
perception.
