Advanced Methods for 3D Video Capturing and Evaluation
Kaller, Ondřej ; Klíma, Miloš (oponent) ; Masopust, Jiří (oponent) ; Kratochvíl, Tomáš (vedoucí práce)
The thesis focuses on advanced methods for 3D image and video capturing and evaluation. Based on a brief summary of spatial perception principles and the description of the state of the art in the areas of adaptive parallax and cameras configuration for traditional stereo pair shooting, especially up-to-date possibilities of depth map estimation are analyzed. Both active and passive methods are discussed; profilometry scanning is explained in more details. Qualitative parameters of two typical present systems of 3D displays are compared. The analysis is made for polarize discriminated and time multiplexed 3D displays technologies. Crosstalk between left and right images has been also measured. The core of the work consists in the design and testing of a new method of more precise estimation of the depth map in 3D videos. The novelty of the proposed approach lies in a sophisticated combination of partial results obtained by selected existing passive and active 3D scanning methods. The aim of the combination is to overcome drawbacks of individual methods and this way, to improve the accessible precision of the final depth map. The active method used is incoherent profilometry scanning which fails on surface discontinuities. As a passive method, a stereo pair matching is used. This method is currently the most widely applied method of depth map estimation in the field of 3D capturing and is available in various implementations. Finally, subjective tests of 3D video quality of experience (QoE) are dealt with. The most important outcome here is creation of the objective metric for the best estimation of subjective stereoscopic video quality.

Stereometric LED display
Kováč, Michal ; Macháň, Ladislav (oponent) ; Bohrn, Marek (vedoucí práce)
The bachelor thesis deals with the design of stereometric display made of the mesh of RGB LED arranged to the matrix of 8x8x8. The thesis copes with the options of diodes’ arrangement according to minimization of number of leads as well as building process of desired mesh. The device is controlled by FPGA circuit on the development board Spartan-3 Starter Kit and control circuit is described in the thesis. The information about displayed text and animations are transmitted into the circuit from computer through USB interface. The display is created, apart from Spartan-3 Starter Kit, by two connected boards which design is also described in the thesis. The first one presents the stereometric display itself with essentials components and the second one provides communication with the computer.

3D Game Exploiting Focusing on Holographic Display
Lisický, Tomáš ; Materna, Zdeněk (oponent) ; Chlubna, Tomáš (vedoucí práce)
This thesis is anylising the possibilities of 3D display in gaming environment, specifically 8.9'' model of the first generation by Looking Glass company. The main emphasis is put on the usage of the given display's focusing, thus in which game mechanics and environments it is usable with desired effect on player and his perspective sense. The thesis' purpose is also to survey the market of available and historical games, which use 3D displays or other stereoscopic elements for visualisation or other purposes. After survey comes analysis of found game genres and their game mechanics, evaluation of their usage, performance and the option of implementation on Looking Glass display. The final product is a short demo of 3D game, which uses these game mechanics in combination with Looking Glass' focusing capabilities. To realise connection between this display and gaming environment, an open-source development platform for PC games – Unity – was used.
