Learning objectives
The course aims at studying how multimedia information is acquired, coded and processed by the most popular applications running on common multimedia systems. For this reason, the course will be focused on theoretical and practical elements particularly important for the manipulation of the three main multimedia modalities, i.e. images, videos and audios, which are the core of modern communication.
Expected learning outcomes
Students will learn the basic notions and tools about how information conveyed by images, videos and audios is handled and processed, which in turns means to be skilled at:
- capturing multimedia information through digital systems such as video cameras, TV or computers
- coding and representing multimedia data using fundamentals and techniques of information theory
- using algorithms and programming languages devoted to multimedia data processing
