Reading Group - Signal Processing & Wavelets

Meeting Time: Mondays 11:30-1:00
Meeting Place: Graphics Lab

Please read about the general goals of this in the "original" webpage.

Note: There is a mailinglist for this reading seminar. Simply send email to with the subject "subscribe sfu-signals". You can then post messages by sending email to This semester we would like to go through the following book:

I suggest to meet once a week to go over chapters or parts of them and to:

Wavelets and Filter Banks

One of the drawbacks of the Fourier Transform is that it is a global transform, i.e. if you change the FT of a signal just a little you end up changing the ehtire signal. Wavelets present a quite robust way of a signal transform that is much more flexible. Although wavelet theory has been around a good century (Haar) it didn't gain much attention until the work by Ingrid Debauchies who made them practical. Since it is a very powerful concept it had revolutionized the fields of Applied Math, Computing Science and Engineering in the past decade. Let's find out why. :)
