The purpose of the course is to give students fundamental knowledge on multimedia signals and technologies for their representation, processing, transmission and presentation. Students will learn to use computer-based tools for multimedia signal processing and composition and will be able to choose and implement suitable algorithms for voice, image, audio and video processing to meet given demands in different multimedia applications.
- define media signals, their representation, processing and applications
- distinguish source coding and entropy coding and various algorithms for media compression
- apply and analyze methods for predictive and transform coding of media signals
- describe human visual perception model and explain properties of video signal
- explain differences between analog and digital video signal representation
- employ methods for image and video signal compression

Necessary requirements to pass the course exam through continuing education are the following: student must attain at least 50% of total points from categories: laboratory exercises, homework and class attendance and at least 50% of total points from midterm exam and written part of the final exam. Student who doesn't fulfill these requirements can not approach the oral part of the final exam. The requirement to pass the course through end of semester course exam is also 50% of total points from categories: laboratory exercises, homework and class attendance
