Image fusion in thermal spectrum
Petrásek, Daniel ; Dvořák, Pavel (referee) ; Mekyska, Jiří (advisor)
In this paper, there is mentioned necessary theory of image processing and fusion, which belongs to a group of the most used ways of image processing in the present. In the first part there is mentioned basic findings of image and electromagnetic spectrum. In the second part there is discussed some facts of infrared radiation, thermal cameras, then it is continued with elementary methods of image focus evaluation, segmentation and noise thresholding. In next part there is introduced scheme of image fusion system and basic idea of its implementation. In the end of this thesis there is described implemented system of image fusion, detailed description of reached results, thesis rating and few ideas of improving whole system.

The relationship between kidney stone formation and the composition of food.
Zbořilová, Eliška ; Márová, Ivana (referee) ; Vránová, Dana (advisor)
This bachelor’s thesis deals with causes of formation and identification of urinary concrements. The theoretical part of this study includes basic definition of problems with urolithiasis, points to risk factors of formation of urinary concrements and deals with their classification in accordance to their chemical composition. Important part of this study has been devoted to dietary habits, because composition of ingested food and daily intake of liquids is very important for formation of concrement in urinary tract. Analysis of urinal concrement and following identification of its composition is absolutely unavoidable for definition of subsequent therapeutic method of treatment of urolithiasis. In the experimental part, infrared spectroscopy has been used for analysis of urinal concrements. The calibration lines of the most frequent two-component mixtures of urinary concrements have been scaled by this method

Short path optical wireless link design
Kovář, Ondřej ; Látal, Jan (referee) ; Diblík, Jan (advisor)
This diploma thesis is focused on design and prototyping of wireless optical link for an indoor usage. In the beginning of the thesis frequency spectrums of infrared, visible and ultraviolet light are described by its typical qualities such as values of attenuation or reflection capability. On the basis of this analysis, a proper wavelength has been chosen for usage at the engineered communication system. Next part is devoted to selection of suitable communication components on basis of its declared qualities. In the following chapter this qualities are in carefully measured and after that they are compared with values provided by its manufacturer. The following section is devoted to design schemes of transceiver modules. After completion of the design the manufacturing of PCB, mounting components and the analysis of their distribution was described. The last part of this thesis deals with testing of created prototype in terms of maximum transmission distances and operating frequencies. At the very end of this project, in one small section ways to improve system characteristics was discussed.

Contactless measurement of temperature
Smrž, Martin ; Rozman, Jiří (referee) ; Balogh, Jaroslav (advisor)
Purpose of this bachelor thesis is get acquainted with problem of non-contact measuring of surface temperature of human body. The teoretical part of this labour deal about physical substance of non-contact temperature measurement, using types of detectors and application of this method to the medicine. In the practical part will focus on design and realization of electrical circuit for non-contact temperature measuring, comunication with personal computer and software solution of program for building surface temperature map of patient. At the end of labour was performed a set of measuring to compare accuracy of built thermometer with commercially available products.
