Entry knowledge

Knowledge on the Bachelor degree level and basic knowledge of image/video compression are required. Basic JAVA programming language knowledge is required.

Rules for evaluation and completion of the course

Evaluation of study results follows the Rules for Studies and Examinations of BUT and the Dean's Regulation complementing the Rules for Studies and Examinations of BUT. Up to 20 points are given for programming during semester. Up to 20 points are given for work on projects. Up to 60 points are awarded for the final examination.
The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.

Aims

The aim of the course is to give students enough information to orient themselves in the field of image and video processing, security, transmission of multimedia data in IP networks, indexing and retrieval of multimedia data in multimedia databases.
Students who will complete this course will be able to:
- describe and explain the basic parameters of digital image and video,
- describe and explain the procedure for measuring the quality of digital image and video,
- explain the transformations used to image/video compression,
- explain the entropic coding used to image/video compression,
- explain the principles of motion estimation and compensation used in video compression standards,
- describe and implement individual parts of JPEG and MPEG compression,
- describe current compression formats, define their advantages and disadvantages,
- to orientate in the environment of the transmission of multimedia data over the Internet,
- Explain the principles of multimedial content security,
- describe the principles of multimedia databases.
