Laboratory workplace for virtual reality
Budáč, Adam ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor’s thesis is about creation of laboratory workplace for virtual reality. In theoretical part, it’s analysis of various types of devices for use in VR, description of operation principle of these devices used in VR, analysis of modern coding algorithms suitable for use in VR, suitable use of these codecs for 2D, 3D a 360° multimedia content, options of obtaining and playback of this content, comparing the difference against classical displaying methods and quality measurement of this content using objective metrics at different qualities and compressions. In experimental part, there’s described database creation of video content, coding these video sequencies using objective metrics, creation of laboratory workplace for use with VR, creation and sample elaboration of laboratory task dedicated to virtual reality.

Comparison Of Modern Video Codecs For 4k And 8k Video Content
Budáč, Adam
The purpose of this paper is to compare modern video codecs, that ensure delivery of 4Kand 8K video content in high quality at reasonable bitrates. There are compared three video codecs:HEVC, VVC and the AV1. Video quality assessment is ensured by using four objective video qualitymetrics, which are: PSNR, SSIM, VIF and VMAF. For tests, there were chosen two from total ofseven videosequencies with different parameters: very high resolutions, high framerates, wide rangeof spatial and temporal indexes and 3D and 360° projection.
