Sound and Image Processing

The course covers audiovisual signals (speech, audio, music, images and video) and their statistical characterization, perception of audiovisual information, and principles and methods for digital processing of the signals for restoration, representation, presentation and analysis of the different signal types. There will be a special focus of signal compression.

The course shall introduce processing and perception of speech, audio, music, images and video to be able to understand modern methods for analysis, distribution and reconstruction of audiovisual signals.

Knowledge:
- Understand different characterizations of sound and images in the time domain as well as in the frequency domain and their interrelationships
- Understand human perception of sound and images
- Know the principles and technologies of compression techniques for sound and images and their application in communications systems
- Know the principles and technologies of several standards for sound and image processing standards and their typical application scenarios.

Skills:
- Combine previous knowledge and skills within mathematics, statistics and programming with new theory t0o solve practical problems within sound and image processing
- Understand block diagrams for compression schemes for sound and image systems and understand signal decomposition, quantisation and coding within these.

General competence:
- Collaboration on solving a practical project
- Quality evaluations og sound and images in typical applications within entertainment.

Lectures, volunteer theoretical exercises, practical semester work with corresponding theoretical introduction through lectures and a theoretical study which will be performed and reported as by group work. The assessment will be group based. Portfolio assessment is the basis for the grade in the course. The portfolio includes two term papers (15% each), a report (20%) and a final written exam (50%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. Non-regular exams might be oral.
