Summary

Audio and Video Signal Processing Methods in Control Systems is continuing knowledge from Bachelor's study programs dealing with continuous and digital signal processing and system analysis (Signals and systems, Digital signal processing, etc.). At the same time it complements the knowledge from Master’s study dealing with signal processing methods (Advanced methods of signal processing). It is intended for students and engineers of electrical engineering, focusing mainly on measurement, regulation, control and signal processing. The student acquires and extends his / her knowledge and skills in the problems, concepts of methodology of audio and video signal processing methods. The students learn the unified methodology of description of audio and video signal recording, audio and video signal processing of using selected algorithms, propagation of audio signals, digitization of audio and video signals, analysis and synthesis of audio signal, compression of audio and video signals, basics for speech signal processing. Students also have knowledge of signal processing methods such as image segmentation, edge detection, image transformation, image signal geometry, image signal filtration, object recognition. Students implement selected basic methods of audio and video signal processing in digital technology, microprocessor and processor technologies. Basic knowledge of mathematics and signal processing in the scope of the basic courses lectured at VŠB TU Ostrava, the FEI, basic knowledge of physics, elementary knowledge of electrical engineering and digital technology. Students also learn implementaion of algorithms of discussed methods into the mathematical program and microprocessor, respectively. processor technologies for processing and analyzing audio and video signals. Students use digital technology, measuring instruments, microprocessor technology, processor technology. Audio and Video Signal Processing Methods in Control Systems are a one-semester object covering the scope of the basics audio and video signal processing. For more information, see the website of the Department of Cybernetics and Biomedical Engineering, FEI, which provides the subject.

Way of continuous check of knowledge in the course of semester

Student realizes projects No.1-10 from the part in laboratory exercises. Projects consist of signal processing, measurement, analyses of video and audio signals using digital technologies, microcomputers and processor technology with mathematical software. The student will prepare 10 project protocols. For each protocol, student can obtain to 2 points. For all protocols, the student can get a maximum of 20 points. At the end of the semester, the student will pass the final test for which he / she can get up to 20 points. Conditions for obtaining a credit: The student has worked out and has been classified all the protocols and if he has realized a test and he has received a total of at least 15 points. Protocols are processed during the semester in the laboratory hours. The course is finished by the final exam, which consists of a written part 0 - 50 points and oral part 0 - 10 points.
