Child Cries Detector
Sobotková, Šárka ; Jehlička, Karel (referee) ; Sekora, Jiří (advisor)
The thesis discusses the emergence of a baby cry, function and spysiological description of the vocal tract. First, the cry of children´s records scanned and made time-frequency analysis, from which it was identified in which frequensy band found the child crying. Further work includes a block diagram of the device and description of each piece. Standing position was devised in the field of soldering, and its functionality verified.

Test of immissions on the medical workplace.
Macková, Pavlína ; Fedra, Petr (referee) ; Jehlička, Karel (advisor)
Bachelor’s thesis deals with the possibilities of measurement and test immissions on the medical workplace. It acquaints with the gasses immissions occurring mainly on the surgery. It is focused on possible ways of detection. The Bachelor’s thesis describes techniques of detection offered by companies Brüel & Kjaer and LumaSense Technologies. For comparison, there is given the possibility of detection by Geotechnical Instruments. The final section is dedicated to system of measurement air immissions on the medical workplace, especially to surgery.

Binocular vision and anaglyph production
Truhlář, Jindřich ; Jehlička, Karel (referee) ; Fedra, Petr (advisor)
Bachelor thesis is focused on explaining the matter of stereopsis and clarifies the origin of stereogram using geometry. Next part deals with the process of shooting stereogram including important settings of the cameras. The work describes and compare several possible approaches of viewing stereoscopic images, especially anaglyph. In the last practical part two aplications for shooting and editing stereoscopic images are introduced. I enclose few photo examples .

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
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
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.
