- Final There will be no final exam
Each midterm will account for 30% of the grade. The remaining 40% will be based on homeworks and a project. There will be around 4 homeworks and the project will be due at the end of the semester.
This semester I will use the Blackboard system offered by DEN to post assignments and solutions, as well as grades. Please register with DEN and create your DEN profile as soon as possible by following the instructions on the <a href="http://den.usc.edu"> DEN Webpage</a>.
EE 483, Introduction to Digital Signal Processing, or equivalent
course. Please note that the course will assume some knowledge of standard
DSP concepts as well as of some basic linear algebra. If you took these
two courses some time ago it would be a good idea to review some of the
key material early in the semester.
MATH 599, Introduction to Wavelets, and EE 569, Introduction to Digital Image Processing. None of these courses is required.

Material covered (Note: based on the material covered in Fall'04, subject to change)
- Weeks 1 and 2 Introduction and Motivation. Signal representation using bases. Hilbert spaces. Orthogonal, bi-orthogonal basis and overcomplete expansions. Example: representing finite energy continuous signals using Haar basis. Example of construction of Haar basis
- Week 3 Bases for discrete signals. Finite and infinite dimensional spaces.
- Week 4 Overcomplete expansions. Searching for the best representation. Matching pursuits and variations. Compressed sensing.
- Weeks 5 and 6 Multirate signal processing. Filterbanks and discrete wavelet transforms. Time domain, frequency domain and polyphase domain representations.
- Week 7-8 2-Channel orthogonal filterbanks. Iterated filterbanks. Bi-orthogonal filterbanks. Lifting factorizations. Multichannel filterbanks. Modulated filterbanks.
- Weeks 9 and 10 Multidimensional wavelets. Edgelets, bandlets, ridgelets and other extensions. Lifting for video representation.
- Week 11 Continuous time wavelets. Series expansions of continuous signals. Haar, Sinc, Meyer, Daubechies and Spline wavelets. Mallat algorithm.
- Weeks 12 and 13 Applications. Compression. Classification. Graphics.
- Project requirements:
- Projects should be done individually.
- Each project must involve using the wavelet transform as a tool. A signal is analyzed/classified, etc by computing its wavelet transform and then the required task (e.g. denoising/classification) is performed in the transform domain.
- The Matlab toolbox or C libraries can be used for the project. C libraries are available at <a href="http://www.cs.dartmouth.edu/%7Egdavis/wavelet/wavelet.html"> Dartmouth </a> and <a href="http://math.rutgers.edu/%7Eojanen/wavekit/"> Rutgers. </a>.
- Whichever method is used, the source code will have to be made available along with the project report (only for the routines that you write, which could call those available in matlab or C.)
- Reporting requirements: a final report and a class presentation.
