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.

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.

Test of exposiv partitions in anestetic praxis.
Klimešová, Marie ; Dvořák, Miroslav (referee) ; Jehlička, Karel (advisor)
On anesteziologic workplace are workers meet with various substances and materials every day. Are they put at risk of outbreak of fire or explosion? I´m going to put mind to this issue in my work, which is aimed at monitoring concentrations of explosive substances used in anesthesia. A related study of gases and vapors of volatile liquids concentration, explosiveness, flammability and other properties. I'm interesting in security and the timely identification of gases and vapors of volatile substances of the leak of anesthetic workplace, then studying the detection system and the detectors themselves. I meet with gas analyzers of company Brűel & Kjaer.

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
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 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.

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.
