MULTIMEDIJALNI SISTEMI

After the student passes this exam, he will be able to: - Explain basic mathematical transformations used in multimedia systems: Fourier, DCT transformation, Hermite, Wavelet transformation and time-frequency distributions; - Implement signal filtering in the frequency domain; - Compare basic algorithms for audio signal compression; - Define and illustrate the various steps of Compact Disc encoding; - Practically implement basic types of transformations over a digital image: arithmetic, geometric, image filtering with basic types of filters in the spatial domain, JPEG standard and JPEG2000 image compression; - Explain and illustrate basic characteristics of video signals and basic methods of coding video data: frame types, basic subsampling schemes, motion vector estimation algorithms, MPEG video and H264 standards; - Recommend an approach for the protection of multimedia data depending on the type of signal and the protection concept; - Define basic principle of compressive sensing in modern applications.
