Project 2 - due 4/28
You may work on this project with one other student and, in fact, are
encouraged to do so. If you choose to do so, turn in only one paper
with both names on it. Placing both names on the paper attests that
both of you have participated in the work -- in fact, it should attest
that you have contributed equally.
Your paper should be typed. You should respond to all questions using
complete sentences, proper spelling, good grammar, etc.
In general, answers alone are not sufficient -- you must show
appropriate work and reasoning. You may use available technology,
whether your calculators, MATLAB, Mathematica, or any other. Work
turned in should be neat, carefully written, and complete.
In this project you will be studying a topic of intense current interest:
wavelets. You will be using wavelets to perform image compression (which
is an alternative to the "outer-product" compression that I've been mentioning
in class).

Wavelet Transform
- Perform the equivalent analysis that Patrick carries out, only using your
own examples. For example, the first vector he gives -- (6, 12, 15, 15, 14, 12,
120, 116) -- should be replaced by another of your choosing, which serves
equally well. Use your own image(s). of special interest to you (small might be
better!).
- Materials (including Matlab and Mathematica files for the
analysis) can be found at Patrick's website.
You may consider another project if there's something that you'd
really like to do. Consult with me before doing so, of course, or you're
toast....
I'm going to be giving you all accounts on our wiki, and hope that you will use that to
- learn about wikis
- play with wikis
- exchange information
- present your example
