Detection of face parts in the thermographic spectrum
Šujan, Miroslav ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
Master´s thesis deals with current problems of face detection and its parts in the infrared thermographic spectrum. Most previously published literature deals with the detection in the visible spectrum, making the thermographic detection range an interesting alternative. The work deals with the processing of image signals, images and faces in thermographic spectrum, selected methods of face detection and its parts and also deals with practical system design for detecting facial parts in this spectrum and its subsequent testing.

Workstation with termo camera
Zeman, Martin ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
This thesis contains an overview of physical principles concerning thermography and infra-red sensing, and a specification of a measuring instrument in a measurement system. Next, there are some particular examples of IR sensing applications. In the second part there is a thermal camera market research including individual manufacturers and models with their attributes and prices. There is a closer view of the thermal camera used for this thesis (Guide EasIR-4). In the end of the thesis there are some drafts of computer vision subject tasks (or practices), including workplace designs and solutions, and three task suggestions for bachelor or diploma theses including solution verifications.

Thermal measurement
Zachar, Martin ; Lisý, Martin (referee) ; Kracík, Petr (advisor)
This thesis deals with theory of thermal measurement with both physical as well as technical side. Thesis describes basic methodics of thermal measurment and further compares few different thermographic cameras at the current market. Main part of the thesis is focusing on a script, that has been created in program Matlab, serving for analysis of a series of thermographic pictures capturing verticaly placed pipes, following by registration of founded temperatures to Excel and drawing of diagrams of the change of average temperature along pipe and histograms of temperatures of given pictures.

Temperature measurement
Brzobohatý, Lukáš ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
ABSTRACT Brzobohatý Lukáš: Temperature measurement The work presents a comprehensive overview of measurements of one of the basic state function determining the state of matter - the temperature. It deals with development of temperature scales, units and measuring devices. Temperature measurement is divided into two basic ways - contact and non-contact method. Contact measuring devices emphasis on thermocouples because of their indispensability in all industries. Non-contact temperature measurement is most developing method. This corresponds to the devices development, which is determined by the rapid computer technology development.

Kontrola technického stavu mechanizačních prostředků pomocí termokamery
HALÍŘ, Vladimír
Main topic of this research is possibility of use the infra-red radiation of materials for purpose of machine diagnosis in agricultur machinery. Non-contact method of temperature monitoring is possible with special camera called infravision camera. With this device is possible to scan surface temperature of monitored object. Output of this scan is called thermogram. For users are values of scan then shown in false colors that are corresponding with a surface temperature of an object. In agricultur machinery the use is where the prerequisite for high increasing friction is converted into heat. Abnormal increase in the operating temperature can then be attributed to different severity of value and used as an indicator of the degree of wear for a possible future state of failures. The result of this research is a summary description of the factors that influence its impact on technical parameters of machine parts. The principles for the proper capture of thermal images, so-called thermograms, and procedures appropriate for their evaluation are described to. Theoretical assumptions are practically tested for the use at normal operating diagnostics of machines and their components.
