Course detail

Multimedia Data Processing

FEKT-MKC-ZMDAcad. year: 2023/2024

The Multimedia Data Processing course describes in detail the principles of compression of digital images and video sequences. It deals with a detailed analysis of the techniques used in the current compression standards JPEG, MPEG, H.26x. It also focuses on the protection of image data in particular by watermarking techniques, streaming techniques and Digital Rights Management (DRM).

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 is to provide students with sufficient information for orientation in the field of image data processing and video sequences, their security and transmission in IP networks. 


The graduate of the course is able to:

- describe and explain the basic parameters of digital image and video,

- describe and explain the process of measuring digital image and video quality,

- understand and explain the transformations used in video image compression,

- explain the entropy coding used in video compression,

- explain the principles of video estimation and compensation used in video compression standards,

- describe and implement the different parts of JPEG and MPEG compression,

- describe current compression formats, define their advantages and disadvantages,

- navigate the environment of multimedia data transmission over the Internet,

- explain the principles of multimedia content security.
