Binocular vision
Hanus, Rostislav ; Hrubeš, Jan (referee) ; Fedra, Petr (advisor)
This thesis is concerned in the binocular, or a spatial vision and stereoscopy. The first part is about the physiology of spatial and principle of vision. Next point of the work is addressing the implementation of synchronous scanning of static scenes using a pair of identical cameras. Implementation was carried out by two remote-controlled IR triggers. Another chapter is about stereoscopy, which is solved by the principle of image processing at a final spatial image. Image processing of stereo images is solved by using anaglyph. The last chapter describes how to build a program that is part of the work.

Binocular vision and anaglyph production
Šanoba, Ľuboš ; Jehlička, Karel (referee) ; Fedra, Petr (advisor)
The aim of my semester work was to study physiology of binocular vision for perception of third dimension of two- dimensional images by using stereoscopy technology and glasses with colored filters. It is necessary to introduce this problem by explaining how our visual sense works included a post-processing of visual information in a brain. Next part of work deals with stereoscopy, technology of capturing images with two identical cameras to create perception of third dimension in spite of two dimensionality of image. It was necessary to explain how camera works as well. Favorite technique of stereoscopy is anaglyph.

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.

Binocular vision
Portyš, Jakub ; Kolář, Radim (referee) ; Provazník, Ivo (advisor)
This paper follows up theme of binocular vision and his working in daily life. The individual chapters contain anatomy and physiology of visual organ. In detail are discussed physical principles of binocular vision. Discussed are also development, eventual pathologies and examination methods of human binocular vision. Theoretical introduction defines the concept of stereoscopy and states overview of stereoscopic imaging methods. Paper also includes approaches to recording of three dimensional image and camera settings. Practical part of work is dedicated to the selection of shooting methods and design of dynamic scenes from daily traffic. Introduced is also the projection method of captured scenes to the group of viewers. The last chapter analyzes the method and evaluation of the experiment itself and the resulting conclusions.

Binocular vision
Brňák, Jan ; Hozman, Jiří (referee) ; Fedra, Petr (advisor)
This masters thesis deals with the physiology of binocular vision people for obtaining two dimensional spatial perception of images with glasses. There are developed theoretical part of the physiology of vision, then writing available methods that are now widespread for obtaining stereoscopic scene. The work also describes shooting dynamic scene using a pair of identical cameras. It focuses mainly on OFF-AXES method and deals with the topic of the settings stereoscopic base. There is also realized a practical part, which works with the capture dynamic scenes using video cameras with a automatic control of cameras distance. Automatic control is performed using the parallel port and a stepper motor. For this purpose it is designed to work in hardware support and a program for mutual communication. Filmed a short movie was screened to a group and those observers evaluated the parameters that were specified in the created poll.

Binocular vision
Brichta, Tomáš ; Jehlička, Karel (referee) ; Fedra, Petr (advisor)
In this work I have been briefed by physiology of binocular vision for acquisition of three-dimensional perception from two-dimensional images using special glasses. At first I described optical organ, after it I described physiology of binocular vision. In the next part of my work I described stereoscopic imaging technology and their advantages and disadvantages. In the next part of this work I have designed method for measuring ideal distance between cameras for scanning and projection of stereoscopic image using program Inition StereoBrain Calculator. After scenes design I have collected visual data for creating 3D videos. This videos were been projected to the group of the viewers. Data from the viewers were been analyzed afterwards.

Binocular vision and anaglyph production
Pospíšil, Pavel ; Šanda, Jaroslav (referee) ; Fedra, Petr (advisor)
This work concerns physiology of binocular vision and stereovision. The main topic of this work is the production of anaglyphs. The first part introduces anatomy of the eyes and principle of binocular vision, which is the stereoscopic production based on. The second part introduces the individual methods, it's processes and technical implementation for three-dimensional presentation with focusing on answering questions connected with production of anaglyphs. At the same time the M-script ANAGLYPH was developed, which provides connection with two external cameras and becomes high-quality element of anaglyphs production. All anaglyphs were photographed with couple of Logitec C120 or couple of Canon 450D cameras. Final anaglyphs were presented to a group of observers and they were given question forms. Subjective opinions of observers were statistically analyzed. The electronic version of this work and all the files and data are included on attached DVD.

Pleoptic and orthoptic training for visually impaired children in preschool age.
ŠTOČKOVÁ, Šárka
The theoretical part of this bachelor's paper is aimed at the development of visual perception since the child{\crq}s birth until pre-school age, and further at pleoptic and orthoptic training. The paper also mentions the anatomy of the organ of vision, and the eyesight impairments of childhood. The theoretical part examines in more detail binocular vision, as pleoptic and orthoptic training are aimed exactly at binocular vision impairments (strabismus and amblyopia). The practical part presents the results of the research, which was focused on eye/hand coordination of pre-school children in an ordinary nursery school and in a nursery school for visually impaired children. The research part was performed by means of controlled observations in both types of nursery school. In total, 200 controlled observations were performed. The objective of this bachelor's paper is to establish the level of visual coordination of children in a nursery school for visually impaired and in an ordinary nursery school. My hypothesis was stated as follows: ``Because children in a nursery school for visually impaired develop visual coordination also by means of pleoptic and orthoptic training, they have better visual coordination compared to children in an ordinary nursery school, who develop visual coordination only through games and drawing{\crqq}. Upon comparison of the results from the two nursery schools, the research has proven that children of pre-school age in a nursery school for visually impaired have better eye/hand coordination than children of the same age in an ordinary nursery school. Thus, my hypothesis proved true. The paper could serve as a study material, as those issues are not comprehensively elaborated in any publication.
