Subject: Re: Request for Road Images
From: stevea@vast.unsw.edu.au
>From Vision-List digest 11.42:
I am interested to get sequence of road images (24 bits color) taken
from a mo ving car. Road sign of any type should be visible along the
road.
There are several places you can get this sort of imagery.
Probably the best site though is cicero.cs.umass.edu, which is the home
site of Allen R. Hanson and Edward M. Riseman (of image segmentation
fame). They have a great liking for roadside images in their
experimental results, and there are many samples there. Please note
though, that not all of them have road signs in them. The directories
you probably want most are area_road_scenes and amherst_roads.
Another site that has a set of images that may be helpful is
isy.liu.se, which has a video sequence taken from inside a car. This
sequence contains one prominent road sign, and possibly one or two more
further away from the camera involving road works.
I hope this info is useful for you.
cheers

"Why have you two eyes and just one mouth?" -Ryuchi Sakamoto
Here is the content of the file README.image_files that is located
in the home directory at this site:
This directory contains the image library of the VISIONS group at
UMass/Amherst. Each sub-directory contains a specific sort of image:
Typically the name of the directory suggests the sort of images in the
directory.
There is also an interactive DB of image descriptions available. Telneting
in as 'visimgdb' to cicero.cs.umass.edu will place you in an interactive
program which will allow you to search a data base of image descriptions.
The data base and the program to access are also available for FTP'ing
in the directory imdb (the data base is vis-imagedb.ilb* and the program
source is in image_db.tar.Z).
Most of the image data is in what we call "Universal Plane File
Format" - this is a variation of our LLVS plane file format. The
directory 'universal_plane_file_format' contains documentation
describing this format as well as code to read these files on several
different platforms. These plane files always have an extension of
'.plane'. Plane files should always be transfered in binary mode.
If you have questions or can't find a particular sort of image, let us
know by sending E-Mail to me Robert Heller (systems programmer)
<heller@cs.umass.edu> or Val Conti (Lab Manager) <conti@cs.umass.edu>.
Jan-15-1991 - by popular request, some of the motion data files have been
collected into tar files and compressed. Also, all of the files in
'universal_plane_file_format' have also been collected into a tar file
and compressed. This has been done to make FTP'ing easier. RPH.

Subject: Signal to Noise ratio Question
Could someone tell me if the following phrase make sense ?
"A signal to noise ratio of a SAR image is 1 or 2".
My question is: Is it possible to assert the signal to noise ratio
of a two dimension signal(say grey scale image) without considering
some noise model. It seems like there is some way of obtaining the
signal to noise ratio as a measure of how good or bad the signal is.
In other words, my question boils down to the one of how to separate
signal and noise component. Any ideas or references will be
appreciated.
Thanks in advance.

Subject: Plausible pattern recognition (Info needed)
Keywords: plausible pattern recognition
Hi, I'm doing some research on pattern recognition. The domain I'm working
on has a special feature that seems interesting (at least to me:-) in general.
I'm looking for any special technique that handles this situation or any
opinions on whether this feature exists in any other domains.
I'm trying to develop a system to recognize what a user is drawing on a CAD
(Computer-Aided Design) screen. This looks like a very general pattern
recognition problem. However, in this domain, there's no need for "perfect
recognition." That is, my system only needs to suggest a fixed number of
objects that look similar to what the user is drawing, possibly ranked by
the "similarity" between the suggested object and the user's input, with the
most similar one output first. So, a good system should output the target
object as soon as possible, but not necessarily get it right at the first place.
I call this type of problem "plausible pattern recognition," meaning that the
recognition only needs to make plausible suggestions, not the perfect one.
To me, this type of problem seems to reduce the difficulty of recognition
and is more doable than trying to find a "perfect" system. If you came
across something similar to this type of problem or have some opinions on
whether "plausible PR" is important theoretically or practically, please let
me know. Both emails and followups are welcome. Comments, references, and/or
critics are all greatly appreciated.

GENERAL DESCRIPTION
Labo Image is a window based software for image processing and analysis. It
contains a comprehensive set of operators as well as general utilities. It
is designed to be open-ended; new modules can easily be added. The software,
written in C, is now based on X11 / OSF Motif. The current version has been
developped and tested on a Sun SPARC station, with X11r4 and Motif 1.1.
LaboImage has been extensively used by students as well as researchers from
various domains: computer science (image analysis), medicine, biology, physics.
It is distributed free of charge (source code).

MEANS OF DISTRIBUTIONS
LaboImage source code is available by anonymous ftp at:
1) ftp.ads.com, login name anonymous, in pub/VISION-LIST-ARCHIVE/SHAREWARE.
2) peipa.essex.ac.uk, login name anonymous, in ipa/proc-src.
If you have no access to ftp, please contact the author.
If you wish to be kept current with update, error reports, ..., please send
us a mail with your full name, regular and electronic addresses.
DISTRIBUTION POLICY
In essence:
- this is a non-profit software, but it is our property and the copyright
notice must appear;
- the reference to cite in case of published results obtained with Labo
Image is: "A. Jacot-Descombes, M. Rupp, T. Pun: `LaboImage: A portable
window-based environment for research in image processing and analysis',
SPIE Symposium on Electronic Imaging Science and Technology, Image
Processing: Implementation and Systems, San Jose, California, USA,
Feb. 9-14, 1992.
- no responsibility is assumed;
- not to be used for profit making purposes;
- bugs will usually be corrected since we use the software intensively ;
- modifications should be communicated to us, with (normally) allowance
for redistribution.
PAYMENT
Athough LaboImage has undergone many upgrades and suffered in the hands of
many users, the current version is certainly not bug free. For the time being,
we require NO prepayment, return postage or anything.
We may however change this policy in the future, and ask for nominal fees to
cover material expenditures. HOWEVER, if you are satisfied with the product,
why not send us some "souvenir" (post card, drink, etc.)) from your country...??!!
CAPABILITIES
Labo Image is an interactive software, whose interface is menu, mouse and
window based. Its main features are:
- input-output: LaboImage format file, SUN raster file; postscript;
- display: mono, RGB, dithering, color table editor;
- preprocessing: filters (median, high pass, low pass: hamming, gauss, etc),
background subtraction, histogram equalization;
- processing: thresholding, Fourier transforms, edge extractions: various
operators, ridge-riding, zero-crossing; segmentation into regions,
binary and gray tone mathematical morphology;
- measures: histograms, image statistics, power, region outlining,
object counting;
- auxiliary: conversions, arithmetic & logical operations, noise addition,
image generation, magnification, convolution/correlation with
masks, image; padding;
- elementary interactive operations: region outlining, statistics and
histogram computation, etc.;
- special tools:
- modify image at pixel level interactively,
- one-dimensional gel analysis,
- expert system for image segmentation (not implemented in LaboImage 4.0);
- macros definitions, save and replay (not implemented in LaboImage 4.0);
- on line documentation.
IMAGE FORMATS
Own format: descriptor file + data file (binary, byte, int, float, complex;
mono or RGB). Supports also Sun raster format. Conversions to various other
formats.
Data structures:
- iconic (pixel-based), with each image having its own parameter list;
- vectors (histograms, look-up tables);
MISCELLANEOUS REMARKS (answers to commonly asked questions)
- FILE FORMAT: we decided to go for: 1) a machine independant format; 2) a
simple, data (ie. signal) oriented format. At the beginning of the
development (summer 1987), we were not aware of any image format used by
the whole community. There seems now to be some progress on the matter
(TIFF, etc.), but they are still not that widely used in the community.
Also, due to development priorities we consider conversion routines a more
secondary issue as long as our format is simple.
In addition, the menu "ACQUISITION=>free byte format" is fairly versatile.
Also, the SUN raster images can now be read into LaboImage and likewise
images on system may be stored in SUN raster format.
However.. we would welcome any software contribution!
- 3D IMAGE PROCESSING: nothing special for such images.
- ON LINE HELP: available.

Subject: AAAI '93 : Call for Papers
Call for Papers
AAAI-93
AAAI-93 is the eleventh national conference. The purpose
of the conference is to promote research in artificial
intelligence (AI) and scientific interchange among AI
researchers and practitioners.
Papers may represent significant contributions to all
aspects of AI:
a) the principles underlying cognition, perception, and
action in humans and machines;
b) the design, application, and evaluation of AI
algorithms and intelligent systems; and
c) the analysis of tasks and domains in which
intelligent systems perform.
In recognition of the wide range of methodologies and
research activities legitimately associated with AI, we
invite authors to submit papers describing both
experimental and theoretical results from all stages of
AI research. In particular, we encourage submission of
papers that present promising research directions by
describing innovative concepts, techniques, perspectives,
or observations that are not yet supported by mature
results. To be accepted, such submissions must include
substantial analysis of the ideas, the technology needed
to realize them, and their potential impact. In addition,
because of the essential interdisciplinary nature of AI
and the need to maintain effective communication across
sub-specialties, we encourage authors to position and
motivate their work in the larger context of the general
AI community. While papers concerned with applications
of AI are invited, those that describe working
commercial systems should be submitted to the IAAI
conference.
Requirements for Submission
Authors must submit six (6) complete printed copies of
their papers to the AAAI office by January 13, 1993.
Papers received after that date will be returned
unopened. Notification of receipt will be mailed to the

Thank you for everyone that supplied me with information. Special thanks to
MS and EM of Sun Microsystems (both worked on the videopix card project) for
all the their help.
*** Users Comments ***
1. I have used the videopix here in the USA. It seems to work OK for me. I
don't know how high a video quality that you need but the videopix only has
7-bit analogue to digital converters. I don't know of anything else in the
same price range but I haven't looked for about 1.5 years.
2. We have three or four VideoPix boards and are very happy with them.
They're not full-motion though, so if this is a requirement for you then the
VideoPix may not be what you want.
The boards can capture and display about 15fps of greyscale video in a small
window. As you increase the size of the window (and hence the amount of data
which needs to be blitted through the window system) and add color, the
capture and display rate drops and eventually bottoms out at about 5fps for a
fairly large color window.
The board comes with a nice software library and a GUI interface, and seems
to be a well thought-out product. We've had no complaints at all.
3. I've used the Sun VideoPix card. When it comes to grabbing single frames
(motionless) it's OK. I use the PAL-format, which gives about 720x575
pixels. NTSC gives, I think, 640x480. Also, it stores 7 bits of luminosity
per pixel, and 2*7 bits of chrominance per every four pixels. So, the
color-information appears a bit slower than the intensity. Maybe this is only
natural. The eye might be better at intensity differences than those of
color.
To grab a movie in realtime is harder. I've managed to grab about 6 frames/s,
on a Sparc 2, each frame having a resolution of 320x240 full color. Full
frame-rate would be 25-30 frames/s.
4. I have messed around with the videopix card quite a bit, and it seems to
be a viable tools for conferencing, image-oriented mail and multimedia, etc,
but does not produce the quality required for high-end image processing
applications.
5. We have one of these boards here at ANU, but we just got the thing so we
don't have much experience with it so far. It can display about a frame a
second from live video or TV in color, but the quality isn't as good as I
expected. That may be a result of the poor quality signal from the TV though.
It can do a few frames a second in black and white. The frame grabs work
pretty good, but it is hard to get the exact frame that you want.
*** Technical Specification ***
1. Colour (8 and 24 bit)
Yes.
2. Greyscale (256 levels)
Yes.
3. Monochrome
Yes. 1bit per pixel file saves are available. All functions work on 1bit
frame buffers, also.
4. A resolution of 512x512 or better
Square pixel PAL resolution is what you get from the VFCtool software, but we
also have an API that lets you get the full non-square data. So you can
customize your software to control VideoPix directly. The API isn't a
specific tool per say, but a list of defined driver calls.
5. Video input
2 Composite (NTSC or PAL), 1 S-Video (NTSC or PAL) all software selectable.
6. Continuous Frame Gabbing - (what is the max frames grabbed per sec ?)
Ah. This depends on which mode (B&W or Colour) and what display resolution
you selected from the software. Basically it's:
mode resolution (displayed) FPS
Colour Full (640x480 NTSC) 1
Colour Half (320x240 NTSC) ~3.5
Colour Quarter (160x120 NTSC) ~5
B&W Full (640x480 NTSC) ~3.5
B&W Half (320x240 NTSC) ~6.5
B&W Quarter (160x120 NTSC) ~8.5
The fastest library routine that is supplied might be able to grab 15 fields
per second, NTSC, in raw YUV format.
*** Technical Explanation ***
The ADC's are a full 8 bits, But the SAA9051 Multi-Standard Decoder operates
only on 7 bits. The output of the decoder is 4:1:1 digital YUV data that is
stored in the boards FRAM. There is a full frame of FRAM on the board for
either NTSC or PAL.
Basicaly the board looks like this:
input conn -> SWITCH-AGC-FILTER-ADC -> SAA9051 decoder-> FRAM ->SBUS
input conn -| | |
input conn -| --------I2C UART -----
What happens along this decode path is this:
1. The video source is supplied via the input connectors. Which input is
selected via the software. Commands are send through I2C bus to tell the
decoder which input has been requested.
2. Now the video has been selected, the ADC now gain adjusts the video levels
and low pass filters the signal to trap out un-wanted noise above 6.5Mhz.
Then the video is buffered and sent into the ADC. The ADC digitizes the CVBS
signal with 8 bit resolution. The data is then sent to the decoder.
3. Now the data is taken into the SAA9051 decoder. Although the part has an
8bit hardware interface to the input ADC's, the internal resolution that the
chip operates at is only 7bits in the (y) luminance path. The color
information (c) is decoded and sub-sampled and then outputed with the (y)
information to produces a 4:1:1 digital YUV output data stream.
4. The information is now stored in the on-board 1 Meg FRAM (Field RAM)
buffer at video speed. FRAM is a memory specially designed for use in video
frame store applications. It was first used in televisions that had
Picture-In-Picture (PIP) processors. It now can be found in most high end
VCR's being used for time base correction applications or in digitizers like
VideoPix. FRAM looks like a big FIFO, and is in fact read like a FIFO. But
it's storage cell can hold an entire field of PAL (or NTSC) video. Now that
this information is held in the FRAM, The application can now access it from
the SBUS. This is where the speed bottleneck is.
5. SBUS. Once the data is requested, it is sent in it's raw YUV data form
into the host memory via VideoPix's slave interface. The data transfer speeds
are fast, but not fast enough for real-time transfers (30FPS). This amount of
data is in the order of ~20 MBytes/sec which requires an expensive (at the
time) DMA interface. This also swamps SBUS disallowing of transactions to
occur from other SBUS cards. Since SBUS is considerd a general purpose I/O
bus and not a high speed video bus, it would be wrong for any SBUS card to
take more than 50% of the bandwith at anytime.
The net results is that we have an upper limit as to how fast we can transfer
the data from the card to the host ram.
6. Once the data is in the host, the software does several things to it. The
data arrives as 4:1:1 coded YUV non-square (4:3 aspect) pixels. In order to
display this on the console, the data is transcoded to RGB and dithered if
the framebuffer is only 8bits. It is then sub-sampled to render a square
image. This basicaly means dropping every fith pixel.
7. The data is now bit-blited to the display for you to enjoy!.
*** My thoughts ***
I will be buying one. If your main frame grabber specification is
real time frame grabbing you will have to purchase a different, more
expensive frame grabber. For the price it seems good value for money.
I have two sample jpeg images (90%) grabbed from TV using the videopix card
if anyone is interested.
Thank you again for everyone that sent info to me.
Regards,
Mark
