PANOPTIKON
Hofmann, Petr Eric ; Smetana,, Matěj (referee) ; Vaněk, Vojtěch (advisor)
The chosen output for this master's project is the creation of a 360° animated video, where the image recording is captured in all directions simultaneously. The nature of this video lies in allowing the viewer, based on their activity, to look around the environment of the ongoing action and immerse themselves in the video's environment. Each viewing of the video is unique because the viewer never sees the entire scene at once; everything around them happens in parallel, providing a nonlinear film experience not only from the narrative side but also from the visual side. The final 360° video is interactive, requiring the viewer's active participation to utilize its full potential, as most of the additional content remains hidden without activity and in a static state of the video. This video format shares the property of interactivity with the environment of digital games and can be understood as a hybrid connection of these two media. In terms of content, the project processes Jeremy Bentham's concept of the Panopticon, an architectural object where all its inhabitants should be under constant surveillance. The narrative follows the activities of five characters who, although separated from each other in isolated rooms and are under constant surveillance by the viewer in the observation room, manage to escape from the architectural construct after several unintended mistakes. The main function of the project is to emphasize visual elements strongly from both the content and formal perspectives and thus provide the viewer with an extraordinary experience

Multimedia quality assessment for headset with virtual reality
Majnuš, Robert ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with creating multimedia content for virtual reality and designing a subjective test to evaluate these sequences. In the introductory theoretical part there is information about virtual and augmented reality and several types of virtual reality glasses that are available on the market today. The second chapter focuses on methods of quality measurement and evaluation. These are subjective and objective evaluation metrics. The following describes the different types of codecs that are found in most of the sequences on the Internet portals. Then there is a chapter on creating content for virtual reality. Especially panoramic, 3D and 360 ° videos and photos. In the practical part of this semester work is described by me the procedure of editing sequences for individual codecs and design and use of subjective method including evaluation.

Object Tracking in Panoramic Video
Ambrož, Vít ; Hradiš, Michal (referee) ; Čadík, Martin (advisor)
The master thesis maps the state of the art of visual object tracking in panoramic 360° video. The thesis aims to reveal the main problems related to visual object tracking and moreover focuses on their solution in panoramic videos. In the study of the existing approaches was found that very few solutions of visual object tracking in equirectangular projection of panoramic video have been implemented so far. This thesis therefore presents two improvements of object tracking methods that are based on the adaptation of equirectangular frames. In addition, this thesis brings the manually created dataset of panoramic videos with more than 9900 annotations. Finally the detailed evaluation of 12 well known and state of the art trackers has been performed for this new dataset.

4K Video Player for Virtual Reality
Chvíla, Václav ; Matýšek, Michal (referee) ; Kobrtek, Jozef (advisor)
The subject of this work is the implementation of 4K video player for virtual reality. Theoretical part describes the origin of 360° videos, their compressions and rendering. In design of application was choosed solution with OpenGL, OpenVR, Qt libraries and commercial codec jpeg2000 developed by Comprimato company and for virtual reality device the HTC Vive headset. In part of implementation is analysed problem of shared video memory between libraries and discusses optimalization of the video player. Application was tested in perfomance and by users.

A new Trend in Audio-visual Production? Comparison of Attractivity of 360° Video against a Classical Video.
Svoboda, Adam ; Géla, František (advisor) ; Štoll, Martin (referee)
The work deals with a field of audiovisual production, namely 360ř video format. The thesis is divided into two parts. The theoretical part describes the history and the development of the format. There is also a mapping of the existing use of this format in practice. The second, practical part of the thesis, is devoted to research based on differences in spectator perception. For the purpose of the research, the video material was produced that served as the main point of exploration. Respondents were subjected to qualitative research consisting of two parts. The first was a questionnaire related to the content that the respondents were playing in the video. The second part was the simultaneous observation of the respondents while watching the videos. The work brings interesting results in the comparison of classic video and 360 ř video as well as the findings that solve the question of the direction in which 360 ř video production can be made in the future.
