Processing of Stereoscopic Video Sequence
Hasmanda, Martin ; Šmirg, Ondřej (referee) ; Říha, Kamil (advisor)
The main goal of this master’s thesis was get up used methods for observation the stereoscopic scene with one couple of cameras and find out good solving for processing these resulting pictures for two-view and multiple-view autostereoscopic displays for three-dimensional perception. For methods for acquisition video was introduced two methods. They were method “Off-axis” with parallel camera axis and method “Toe in” with intersections axis. For fit method was choice the method named as “Off-axis“. It was not produces the vertical parallax and in detail was in this work described principle of this method. Further were describe principles off used methods for three-dimensional perception namely from the oldest method named anaglyph after methods for viewing at autostereoscopic displays. The Autostereoscopic displays were main goal of this thesis and so their principles were described in details. For production the result image for autostereoscopic displays was used generation intermediate images between left and right camera. Resulting videos were acquisition for testing scene in created in 3D studio Blender, where was possible setting system of cameras exactly parallel axis. Then were introduce principles processing video where was extract from the couple of cameras where were connected to PC for help digitizing card and next time with two web cameras. Here is not guaranteed exact parallel axis system. Therefore this work try for real cameras achieve exactly parallel axis system by the help of transformations of frames with stereo rectification. Stereo rectification was solving with OpenCV libraries and was used two methods. Both methods work from principles epipolar geometry that was described in this work also in detail. First method rectifies pictures on the basis fundamental matrix and found correspondences points in two images of the scene and second method rectifies pictures from knowledge intrinsic and extrinsic parameters of stereoscopic system of cameras. In the end of this work was described application for implementation introduced methods.

Binocular vision and anaglyph production
Švec, Martin ; Jehlička, Karel (referee) ; Fedra, Petr (advisor)
Objective of this master's thesis is developing and describing of human vision process and anaglyph production. The text contains individual possibilities of achieving spatial sensation from two two-dimensional images. This thesis contains an application for the anaglyph creation developed in the Matlab 2008b interface and description of its functions and properties. Created anaglyphs and the source code sample are attached. The electronic version of the thesis and application are available on the attached DVD.

Binocular vision
Janů, Joshua ; Jehlička, Karel (referee) ; Fedra, Petr (advisor)
This bachelor thesis is focused on binocular vision. The introductory section describes the physiology of stereoscopic vision. Then deals with the so-called depth guides to help induce the audio from the monitored scene. Furthermore, in this paper the method of stereoscopic projection and the possibility of inducing spatial perception of the picture. The work is also the acquisition of stereoscopic recording scene with its projections using anaglyph techniques. Based on the evaluation of the acquired group of alert observers described anaglyph effect of the information contained in the image.

Binocular vision
Němcová, Andrea ; Šanda, Jaroslav (referee) ; Fedra, Petr (advisor)
This bachelor thesis deals with the physiology of binocular vision for obtaining three-dimensional perception from two-dimensional images when using special glasses. It focuses on anatomy and physiology of the human eye and vision as inseparable parts of binocular vision, and on binocular vision as such. The work also mentions terms related to vision and describes the evolution of binocular vision during the human life. The important part of this thesis is the description of the emergence of three-dimensional perception from two two-dimensional pictures (stereogram). The thesis explains the principles of 3D projection methods, especially those which use active or passive glasses, and briefly describes the possibilities of 3D projection without glasses. The practical part includes a plan of capturing dynamic scenes where important parameters which affect the video capturing are described. The plan provides a description of a dynamic scene design with respect to the possibility of verification of human physiological parameters. Described scenes were captured by two identical cameras and edited in appropriate software. These videos were shown to a group of viewers whose task was to evaluate the videos from both subjective and objective points of view.

Binocular vision and anaglyph production
Klíma, Jindřich ; Jehlička, Karel (referee) ; Fedra, Petr (advisor)
The aim of my semester work was to study the physiology of binocular vision for spatial perception of two-dimensional images using glasses with coloured filters, anaglyphs. Since the theme concerns the visual sense, I explained the principle of the vision first. Then I described the principle of physiological development of the vision and the assumptions about binocular vision. The binocular vision is a complex process ongoing in the brain. Therefore, another topic of my thesis was an analysis of three-dimensional objects, space analysis, which unknowingly takes place in our brain. The next chapter deals with stereoscopy, technology which evokes a feeling of depth in two-dimensional images. One of the techniques is obtaining spatial perception by means of glasses with colour filters. In my thesis, I summarized the knowledge about the principle of anaglyphs and I described the principle of obtaining anaglyphs, from shooting the scene, over its creation to its viewing. Finally, here is an example of the program created in Matlab. It is a simple program to obtain anaglyphs from two separate frames.

3D data presentation
Bastl, Petr ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
This bachelor thesis informs about methods for 3D perception. Basic principles of autostereoscopic methods like SIRDS, anaglyph and projection stereo images by two projectors and anaglyphic or polarizing filters are described here. The procedure for generating the view on 3D by means of so-called depth-image-based rendering (DIBR) techniques is analyzed as well. An overview of technologies and formats for projection and simulcast spatial image is stated in this thesis too.

Anaglyphs and their application in teaching stereometry
Matěková, Radka ; Surynková, Petra (advisor) ; Šarounová, Alena (referee)
My bachelor thesis Anaglyphs and their application in teaching stereometry deals with anaglyphs and their creation. It gives information about linear perspective, which is necessary for the creation of anaglyphs. The terms of linear perspective are explained as well as the methods we can use in constructions of this projection. The thesis is mainly devoted to anaglyphs and their creation by the tools of descriptive geometry - central projection and especially linear perspective. Types of anaglyphs, drawing of anaglyphs and the possibility of constructing anaglyphs by software are mentioned. The third chapter deals with stereometry and it uses anaglyphs to support the spatial imagination. There are two versions of the third chapter - each one uses different types of anaglyphs to show the same problems of stereometry. 3D red cyan glasses are enclosed to the thesis as well as a CD containing both versions of the thesis and two files showing the creation of anaglyphs. The thesis is meant to be used by teachers and students in teaching and studying stereometry.
