Coding and compression of media data
2010-2011 - IMT4451 - 10 ECTS

Prerequisite(s)

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.

Topic(s)

  • Motivation for media data compression
  • Media data redundancy and compression
  • Fundamental digital image representation and processing
  • Sampling and quantization
  • Entropy coding, run-length coding, variable-length coding
  • Lossy and lossless compression techniques
  • Transform-based coding
  • Compression of audio, image, and video data
  • File formats and standards
