Prerequisites: Math 250 Introduction to Linear Algebra and Math 251 Multivariable Calculus.
Introduction to Signal and Image Processing by
Discrete Fourier Transform and Wavelet Transforms
This course begins with some topics in linear algebra not covered in Math 250 (such as complex vector spaces, linear transformations, and Fourier series). It then develops the theory of the finite Fourier transform and the new theory of discrete wavelet transforms. These transforms make it possible to separate a digitized audio signal (or twodimensional image) into low frequency components (coarse outline) and high frequency components (detailed features) in a computationally effective way. Then the signal or image can be compressed or noise can be removed using these components.
The course will involve several MATLAB computer projects. Some prior knowledge of MATLAB is helpful but not necessary. A general familiarity with computers and basic programming skills are needed. Purchase of MATLAB software is not required, since you can use the MATLAB software in the ARC and other public computer labs at Rutgers. We will also use the publicdomain wavelet software package Uvi_Wave (which runs under MATLAB).

Note: You can run Matlab on your own computer (without buying the program) by using the Rutgers Xapplication server.
 Click on this apps server link.
 Log in to the apps server using the connect button at the upper righthand corner of the screen and your Rutgers NetID.
 From the Main Menu at the lower left corner of the apps server toolbar, click on Education and then on Matlab
 From the Main Menu click on Internet and then on Firefox Web Browser to access the Uvi_Wave files from the math 357 course web page.
 Copy the Uvi_Wave files into a directory that your create on the Xapps server. Then set the Matlab path to this directory.
