Image and Video Compression
Announcements – Description – Entrance requirements – Exams – Download
NEWS: The certificates are ready and can be
fetched in room 111, building E2.4 (Geschaeftszimmer Mathematik, Frau Voss,
opening hours for certificates: Mon-Fri 8.15-12.00 am).
The updated distribution of points and grades is now available. The results of the second exam are now available. The results of the first exam are now available. The course is designed as a supplement for image processing lectures, to be attended before, after or parallel to them. After the lecture, participants should be able to understand the concepts used in different image and video compression algorithms. We will start with general-purpose entropy coding algorithms such as Huffman-coding or arithmetic coding, discuss adaptive and higher-order entropy coding algorithms, and talk about dictionary methods such as the method by Lempel, Ziv, and Welch (LZW). Afterwards, we discuss image compression algorithms based on transformations (JPEG, JPEG 2000), as well as diffusion-based image compression algorithms before we come to the compression of video sequences. Basic mathematics courses are recommended. Understanding English is necessary. Image processing lectures such as "Image Processing and Computer Vision" are helpful for some topics, but not necessary.
The first written exam will take place on Monday, February 7, 2011
from 2:00 to 4:00 pm in the AudiMO.
It might be advisable to bring a ruler and a coloured pencil. The results of the second written exam can be found here, and the corresponding distribution of points and grades here. The same thresholds as in the first exam have been used to determine the grades (see below). Each student who has participated in the second written exam has the opportunity to inspect his/her graded solutions in room 3.06 in Bldg. E1.1 on Thursday, March 31th, 2011, from 2:00 pm to 3:00 pm. The results of the first written exam can be found here, and the corresponding distribution of points and grades here.
The following thresholds were applied to determine the grades:
Participants of the course can download the lecture materials here
(access password-protected). However, be aware that these slides are only
provided to support the classroom teaching, not to replace it. Additional
organisational information, such as examples and explanations that may be
helpful or necessary to understand the content of the course (and thus
relevant for the exam), will be provided in the lectures. It is solely
your responsibility - not ours - to make sure that you receive this
infomation.
