Introduction
Welcome to the mathematics of multimedia signal processing! In the past
few decades, important theories from mathematics have migrated into digital
communication, image and signal processing, and multimedia visualisation and
data analysis. Understanding these theories confers greater ability to solve
practical problems.
Syllabus
Topics. This course will lead through a list of example
problems in multimedia communication, develop the mathematical
principles useful for their solution, and implement some solutions
using theoretical results discussed in class.
Prerequisites. Math 449 (or Math 404 or Math 405), or the
permission of the instructor.
Time. Classes meet Mondays, Wednesdays and Fridays, 3:00 pm
to 4:00 pm, in Eads Hall room 103.
Text. The lectures will follow the book Mathematics for Multimedia by
M. V. Wickerhauser, ISBN 9780817648794 (2009).
A recommended reference book is Adapted
Wavelet Analysis from Theory to Software by M. V. Wickerhauser, ISBN
1568810415 (1994).
Homework assignments:

 HW #1, due Friday, February 3
(Solutions)
 HW #2, due Friday, February 17
(Solutions)
 HW #3, due Friday, March 3
(Solutions)
 HW #4, due Friday, March 31
(Solutions)
 HW #5, due Friday, April 14
(Solutions)
 HW #6, due Friday, April 28
(Solutions)


Solutions are due at the end of class on the due date. Late homework
will not be accepted. The homework will sometimes require writing a
working computer program, which will be judged for correctness and clarity.
Homework should be submitted on paper, including the printed results of any
programs. However, you will occasionally be requested to provide the
machinereadable program source via email, so find out now how to use your
campus email account.
Tests. There will be one midterm examination on Wednesday,
March 8th, 2017, in class. The cumulative
takehome final examinationhw, which will
emphasize material in the latter part of the course, is due by 12:00 noon on
Friday, May 5th, 2017, in my office, Cupples
I, room 105a, or you may hand it to me at any earlier time.
Grading. One grade will be assigned for homework, one for the
midterm examination, and one for the final examination. These
three will contribute as follows to the course grade: HW 40%, Midterm 30%,
Final 30%.
Letter grades, computed from the course score,
will be at least the following:
Course score at least:  90%  80%  70%  60% 
Letter grade at least:  A  B  C  D 
Students taking the Cr/NCr or P/F options will need a grade of
D or better to pass.
Office Hours. See the instructor in Cupples I, room 105a, on
Mondays and Wednesdays after class from 4:00 pm to 5:00 pm, or by appointment.
