Coding and compression of media data
- 10 ECTS
IMT4991 Mathematics for Signal and Image Processing
On the basis of
Builds on some of the lectures in IMT4811 Image Processing and Analysis.
Expected learning outcomes
This course is a graduate-level introductory course to the fundamentals of coding and compression of media data. It focuses on the fundamental principles of coding and compression and discusses several of the existing audio, image and video compression standards. Students will gain theoretical as well as hands-on experience in media data compression techniques via regular lectures, exercises and a project work.
After completing the course, the students shall have good insight into digital media data coding and compression techniques and related standards
They will also have indepth practical knowledge about the JPEG encoder through the project work.
