Entry requirements

General entry requirements, second cycle

Specific entry

Courses of at least 90 credits at first cycle including the following knowledge/courses. S0001E Signal analysis and S7001E Stochastic signals or corresponding. Good knowledge of signals and systems, and random processes.

Alternative to completed courses can be corresponding knowledge acquired through work within the IT or electronics sector.

Course Aim
After completion of the course, the students should have fundamental knowledge and understanding of:
• Coding and compression of methods for different types of media, e.g., text, audio, images, video (ZIP,MP3,JPEG/GIF,MPEG).
• Basics of the mathematical and statistical principles supporting information theory.
• Basics of the mathematical tools used in compression and coding, such as the discrete cosine transform, wavelets, and the Karhunen-Loeve transform.
The students should be able to:
• Implement various lossless compression algorithms, such as Huffman coding and Lempel-Ziv-Welsh coding.
• Implement and evaluate different lossy compression algorithms for audio, images and video.
• Present and demonstrate their work in written reports.
The students should also be able to assess
• The quality of their implemented compression algorithms in comparison to state-of-the-art codecs.

Contents
Basics in information theory, entropy, limits for data compression, sampling, quantization etc. Transform coding: Karhunen-Loeve transform, discrete cosine transform, subband coding, wavelets. Non-lossy coding/compression: Huffan coding, Lempel-Ziv-Welsh coding (ZIP/PNG), run-length coding. Different types of lossy coding/compressing for audio, images and video (MP3,JPEG,MPEG).

Realization
Lectures, mandatory labs and homework assignments.
