CSS 457 -- Multimedia and Signal Computing

Spring 2010

Prof. Michael Stiber

One of the fastest growing application areas for computers is the processing of multimedia: sound, images, and video. Multimedia places great demands on processing power, network bandwidth, storage capacity, I/O speed, and software design. In this course, you will learn how multimedia information is captured, represented, processed, communicated, and stored in computers. The specific topics we will cover include: physical properties of multimedia source information (sound, images), devices for information capture (microphones, cameras), digitization, compression, digital media representation (JPEG, MPEG), digital signal processing, and network communication. By the end of this course, you will understand the problems and solutions facing multi/hypermedia systems development in the areas of user interfaces, information retrieval, data structures and algorithms, and communications. As a result, you should be well-prepared to work with electrical engineers in the design of advanced signal processing systems (e.g., wireless communication devices) and multimedia computing systems.


Announcements

June 4, 2010: As a reminder, the final is scheduled for Monday, June 7, 3:30-5:45PM, in room UW1-040. See you then!

May 19, 2010: FYI, the passing grade for the midterm was 65%, or 110 points. You can expect a similar level for a passing grade on the final, with a 'B' being at least 80%. Having written that, I still reserve the right to adjust those levels after the test, so just consider those values for the final to be guidelines.

May 5, 2010: The take-home midterm is online. Due in class on 5/12/10.

May 4, 2010: Answers to labs 1-3 are now up on the lab page.

May 3, 2010: Screencast 3, on frequency response, is up. Don't forget the midterm will be assigned this Wednesday; be prepared to ask good questions in class! Also, as a reminder, we now have an updated schedule on the web site, with only a minor modification from the original -- a renumbering of the labs.

March 28, 2010: Our course web site is substantially complete. See the syllabus and the introductory screencast for an overview of the course. Remember that our first meeting will be on Wednesday, March 31!

February 8, 2010: For spring 2010, this class will be operated in a different manner than it has in the past. In particular, we will be using a seminar style. We will meet once per week (each Wednesday), and I will expect you to come to class with questions and a first pass at completing the current lab. Each class meeting will focus on your questions, rather than the entirety of the material. We will still cover the same amount of material as in the past, but a greater degree of initiative and independence will be required of you.

I'll be updating the course syllabus, etc. before the start of the quarter. Please look here for lab 0, which will be posted before the start of the quarter (I'll post a note and send out an email when it is ready). Since our first class meeting will be Wednesday, March 31, you will need to get a start on lab 0 beforehand.
