Recommend a Fourier Analysis Text for Wave Analysis |
Hello Readers,
Please recommend a Fourier Analysis text for learning wave analysis. By
wave analysis, I mean analyzing sets of discrete 2-dimensional data (x
and y location for a specific t) to detect and then measure wave
direction, frequencies, that may be present in the data set.
If there is a well-known text for the subject, please indicate the name
and hopefully my university has it or can purchase it.
I've 2D intensity images aquired at different times that I would like
to analyze for the presence of waves and then determine their
properties over time. I've not done this before and would like to know
any terms to search for relating to fourier analysis (2D) for such a
problem.
Thank you very much in advance,
Marc.

Many image processing programs have a 2D FFT plugin: ImageJ is freeware
and a good place to start. Periodicity in an image will appear as
structure in the FFT. I'd say the first place to start is to simply
install the program and dive in, run some test images if you want to get
a feel for what happens (like a synthetic image of alternating black and
white stripes).

It is not really Mythos, though, and only mentions a few books
in passing. === Edward Lipsett Fukuoka, Japan I'm holding yet
another contest at my blog. The prizes include a DVD copy of
CREEPSHOW, a hardcover copy of the HWA anthology THE MUSEUM OF
HORRORS, and a trade paperback copy of editor David Hartwell's
FOUNDATIONS OF FEAR. So stop on by and look for the post titled
"Daemonyx contest #3." Best regards, Matt Cardin I see that you
will be posting next week on your blog an interview with Mark
Samuels.
I look forward to reading that. Yrs, Michael Thanks for the tip
David... I'm on there now as well.... Willie Start here: Dizum
have helpfully barred my Standard Junk Filter address from use.
He can now be filtered in OE with "". For the servers at work I
use the following naming scheme: Unix: Welsh place names
starting at the beginning of the alphabet and working forwards
(currently zennor, and yeolmbridge) The old scheme was jensrv01,
jensrv02, &c which gives no idea of the platform.

I've been using Matlab as my numerical platform. It can compute a 2D
fast fourier transform, which is nice, however I was interested in
learning about the application to waves themselves. There is a
structure as you say, and that is what I am attempting to exploit.
Thanks
