No, no. You have to treat science as an approximation. As information
goes towards infinity, science goes towards reality. Therefore whe it 
changes it more closely approximates the truth.

Well, thudding in company with Mr Bass, here are a few of my 'mysteries'

(a) We had atoms, then subatomic particles, then quarks.  Is there an
ultimate structure of matter, or will we find more and more fine structure
for ever?

(b) Why has almost every theory of 'small stuff' since Newton thrown up
these wretched infinities?  We have them in gravitation, electrostatics,
classical electrodynamics, and all over quantum physics.  Is this the
consequence of a single bogus assumption, and is that assumption indeed
the assumption that spacetime is continuous?

(c) Are there magnetic monopoles?  More importantly, is there a way to
decide this other than by hunting for monopoles - some simpler experiment
that will disprove one model or the other?

(d) How sure are we that, in the microcosm, gravitational mass is the
same as inertial mass?  How could we ever test this, anyway?

(e) Do antiparticles really travel backwards in time?  I mean, could you
use the spin state of a positron to send one bit of information into the
past?

Well, enough for one day.

Subject: Zoom-FFT + cepstrum analysis. Possible?
Organization: Aalborg University, Inst. of Electronic Systems
Date: 5 Nov 92 23:51:16


I'm currently engaged in a project doing vergence stereo.
For disparity estimation I'm using a cepstrum filter, as
proposed by Yeshurun & Schwartz, Olson & Coombs etc. (se below).
I'm working on 32x32 images, downsampled from 256x256.

When doing the cepstrum transformation, only a small bit
of the transform is really interesting, namely the bit
containing the disparity peak. So, my plan was to use
zoom-fft in the cepstrum transform, so only the interesting
bit is actually calculated, and with greater resolution too.

For people not acquainted with zoom-fft, it's actually just
multiplication of a linear phase factor in the spatial
domain, to perform a shift in the frequency domain. If this
is done before downsampling (e.g. on the 256x256 images),
the resulting 32x32 fft will be a 'close-up' of the
frequency range centered by the frequency shift.

So far, all I've had is failure. My Matlab calculations
do the frequency shift ok, but if I just do a real cepstrum,
the interesting echo peaks just vanish(!).
Trying to do a complex cepstrum gives me big trouble doing
phase unwrapping of the log function. This is no problem
in 1D, but in 2D? 


Having thus described my problem, I call upon the experts
of the net:
  Are my efforts futile, or is 2D phase unwrapping possible?
And if it is, will the zoom-cepstrum transform contain the
desired disparity peak, or does the zooming eliminate the
correlation information?


Holding my breath...

Hello,

	Or, is there a way of keeping track of resource usage effectively
using the existing tag routines. I'm trying to get the GSP/FPU running
in parallel with the processing and host accesses by tracking the current
allocation of resources inside the matrox.
	More questions:
		With the noise that is produced in the images when you
start doing things concurrently (!!), how often do these pixel spikes
appear? after each access (!).
		Has anyone worked out a way of doing normalised correlation
using the processing hardware.
		Can the camera (ASD) capture images in parallel with the
processing operations? (It is supposed to be asynchronous after all)
Thanks

Be careful not to run afoul of some of the basic assumptions of JPEG
and MPEG.

MPEG, and most modes of JPEG, carry out lossy compression.  That is,
the replayed image has slightly different red/green/blue (or YUV)
intensities in the pixels than the original image, but the differences
are small enough such that a continuous-tone image looks acceptable to
the human eye.

However, computer screens (X PseudoColor/StaticColor visual classes,
and VGA images, for example) aren't continuous tone images.  Lossy
compression garbles them pretty badly.  They're more closely related
to laser-printer or FAX images than they are to photographs and motion
pictures.

If you're recording sequences of television images, MPEG might be a
good choice.  To get a look at what it can do, run down to your local
Sears or expensive-gadget store and get a demo of the CD/I (Compact
Disc Interactive) device put out by Phillips.  Some of the motion
pictures in CD/I use 1.15 megabit-per-second MPEG.

Half an hour of MPEG will take a little over half a gigabyte of data.

I don't know of any reasonably priced real-time MPEG encoding
equipment on the market.  Any MPEG encoders currently available
(November 1992) are either slower-than-real-time or costing in the six
figures, at least.  But things are happening fast in this area.

If you're recording what shows up on screen during an interactive
session, you might consider compressing the screen information with
some lossless image compression scheme.

>I am looking for
>applications which would record the output to the screen, which could be

Highland Software, Palo Alto, store@hisoft.infocomm.com (no business
relationship to me) has a software package to record and play back X
demos.  Recording is carried out by protocol interposition (a la
xscope).  This may be closer to what you want.  It certainly generates
a more compact recording.

I saw a brief reference to MPEG (Motion Picture Experts Group), which was
defining a standard for digital motion pictures.  The technique that
they were using was to do differences in the frames.  This would work 
well for the application that I would like.  Realtime capture and playback
of a complete screen.

For those familiar with Unix, there is a "script" command which records all
output to a file.  Greatly extending that concept, I am looking for
applications which would record the output to the screen, which could be 
"played back".  I have posted to these groups before, and many have 
mailed many suggestions which don't quite fit my need.  (Nevertheless,
thank you to all who have responded previously.)

The closest applications to date are Digital Film(tm) by SuperMAC(tm) for 
the Macintosh(tm).  Digital Film uses JPEG compression for highest quality images.  
I may be recording 1/2 hour demonstatrations, and file sizes could be prohibitive
even with compression.  The other option which comes close for X11 is
X/Studio (tm) by Performance Awareness (tm).  I am trying to get a copy
of X/Studio for evaluation.  

MPEG sounds like it might have promise. What do people know about MPEG
applications.

Thanks for your help.
