Subject: Need image (video) sequence source and simulation info on MPEG
Organization: Wayne State University
Date: Mon, 9 Nov 1992 01:14:30 GMT

Hi, I am doing a project on video compression using the latest
International standard (draft), the MPEG algorithm.  Rather, I am
first making a thorough study of the MPEG techniques and as time
permits try to make a software simulation of the building blocks
of the MPEG encoder. I am working on a Sun Sparc 4 workstation.

I am a Computer Science grad student in Wayne State University, Detroit.

MPEG means MOVING PICTURES EXPERT GROUP of the joint ISO-IEC committee
which is developing a world-wide video coding standard (at 1.5 Mbit/s).
The other group is the JPEG for still image compression. 

The purpose of this letter is for asking for help in the following 
directions.  Anybody out there have any sources?

1.  I am looking for an image sequence (video sequence preferably)
    512x512 (or 256x256) gray-scale, 8 bit/pel quantized, suitable
    for use on Sun Sparc 4 station terminal.

    Actually, if anyone knows or has a good test sequence for the
    simulation of MPEG, it would be best.

2.  Although I got quite some info from various tech. papers,
   especially from Proc., SPIE about MPEG and various motion-compensated
   prediction/interpolation encoder development and various motion-
   estimation techniques, and an overview on MPEG as well, I need more
   info for the exact implementation details for the encoder. (esp.
   for software simulation)

3.  Any info on software implementation techniques or algorithms
    for MPEG simulation.  Since the simulation of the whole encoder
    is quite a involved and big project, I was thinking of starting
    with the important building blocks, like Motion Estimator, for
    the MPEG.  

Actually, last semester I could simulate the still image compression
standard, the JPEG, since it is much easier than MPEG moving-picture
compression.

I did try to ftp into isy.liu.se for some image sequences. I was
not able to convert from the .imf format.  When I went into the
vi editor to strip the header from the .imf file, it said line
too long!???

So, I appreciate any help regarding the above directions.
At least you could send me any sources you know!

Thanks a lot,
Bascar.

Hi,

A few weeks ago I posted a request for stereo images. I have had about 10
responses so far. I have found 2 ftp sites with stereo images:

* isy.liu.se (130.236.1.3) in the "images" directory
	breakfast.ic 	-- stereo image of typical swedish breakfast
	calib.ic 	-- stereo image of a building
	frau.ic 	-- 15 frame stereo sequence of a women crossing the street

* ftp.ads.com (128.229.36.25) in the "VISION-LIST-ARCHIVE/IMAGERY/1991-MOTION-WORKSHOP" 
	stereo		-- 10 frame stereo sequence of an office
	stere-motion	-- 6 frame stereo sequence of an army truck

If anyone knows where I can find any other stereo images or stereo image
sequences, please let me know.

Have fun,

Hi Netters,

I am planning to use Adaptive Huffman Coding for images. Hopefully It will 
compress the Bit Per Pixel more than Huffman code. 

Is there any source or place that I can get the algorithm for adaptive 
Huffman code?

Please send a note to my e-mail address.

In yesterday's InfoWorld, there were two articles about Microsoft's Video for
Windows -- code named AVI. Windows 3.1 users will be able to play back video
using compression technology from Intel and Microsoft. Initially, Microsoft is
expected to provide a start-up kit for less than $200.

The product will translate Mac QuickTime movies into Video for Windows movies..
SuperMac Technology will make a VideoSpigot for Windows card to let users play
back video in 640x480 -- the board also translated NTSC and PAL and converts
them into compressed files.

On a low end 386-16, movies play in a 160x120 and 15 frames per second -- This
is the same a QuickTime. On a 486 with video co-processor support, movies can
play at full-screen VGA with 16.7 million colors and 30 frames per second.

Disk space?... The article says the beast eats disk space at the rate of 1MB
per 5 seconds of movie!

Since this is rapidly becoming a FAQable question, I figure I'll go ahead and
take up the net bandwidth.

In Computer Graphics (ACM SIGGRAPH pub?), Volume 25, Number 2 (April 1991)
was a good article by Wayne Carlson (waynec@cis.ohio-state.edu) called "A
Survey of Computer Graphics Image Encoding and Storage Formats".  It is a 
good intro to image compression and described Huffman codes; Lempel, Ziv
and Welch (LZW) adaptive compression; and Run-Length encoding; and other
approaches, as well as the formats of Utah RLE, TIFF, PICT version2, IFF,
GIF, TGA, Sun Rasterfile, GKS/CGI, and CCITT Fax.  It also has a ton of
references to more detailed papers on those formats.

My 2 cents- when appropriate, let's try to use TIFF as a de facto standard-
while it does have its drawbacks, it's more general and prolific than the
other formats, supports lossless compression, and good public domain code 
exists for it (anon ftp to ucbvax.berkeley.edu:~ftp/pub/tiff)...

Sufficient!
What sort of disk space do you have?  Surely anyone doing serious satellite
remote sensing has many GBytes of data, and they keep most of it off line.

I could send you some data, it would be Meteosat Thermal Infra Red.  The ground
truth is all rainfall data as we use statistical relationships to estimate rainfall
for parts of Africa.  A bit unfair on the network though sending satellite data
from the UK.

As for this idea of a new remote sensing group.  What is it that you want to discuss
which is part of remote sensing but not image processing, geography, agriculture,
meteorology?   I think the 'remote sensors' should stay here, sure not everyone
understands everything, thats why this whole news thing is here.  Then again if
you want to talk about methods for collecting ground truth for crop yields,
perhaps this isn't the best place.

"Soar" stands for "State, Operator And Result", and is derived from the basic
execution cycle in Soar of taking a state, applying an operator and
generating a result.

Incidentally, the name "Soar" is now a proper name and not an acronym.

Have you tried the semantic primitives approach advocated by Anna Wierz-
bicka since the late sixties? The fact that it is still around, even
though in a strongly revised format, shows it is surely viable. I have
made her semantic primitives approach part of a semantic framework called
"conceptual axiology", but have not really had the time yet to implement
it to any reasonable extent. Too early to say how "viable" that one is.
I remain hopeful...  :-)

I suspected this was what you were after.  I often hear it referred to as
the "symbol-grounding problem".  Before looking at any of the books you
mentioned were suggested to you (including my own suggestion of Allen),
find Eco, Santanbrogio, and Violi's _Meaning and Mental Representation_.
It's an anthology of summaries of Barwise's situation semantics work,
Johnson-Laird's mental models work, and others.  But I suggest starting
with Yorick Wilks' article, which explains why he prefers "procedural"
semantics to "denotative" semantics, and why he believes Barwise and
Johnson-Laird have both come up short.

You might also want to look for work under the subject heading of
mutual knowledge, e.g. N. Smith and Herbert Clark.
