Classification of retinal blood vessels
Mitrengová, Jana ; Kolář, Radim (referee) ; Odstrčilík, Jan (advisor)
The thesis deals with the classification of the retinal blood vessels in retinal image data. The first part of the thesis deals with the anatomy of the human eye and focuses on the description of the retina and its blood circulation. It further describes the principle of fundus camera and experimental video ophthalmoscope. The second part of the thesis is devoted to a literature search of academic publications that deal with the classification of the retinal vessels into arteries and veins. Subsequently, the principle of selected machine learning methods is presented. Based on the literature research, two methods for the classification of the blood vessels were proposed, the first one using the SVM classifier and the second one using the convolutional neural network U-Net. At the end, the analysis of vascular pulsations was performed. The practical part of the thesis was carried out in Matlab programming interface and images from the RITE, IOSTAR and AFIO database were used for classification and the retinal video sequences taken with an experimental video ophthalmoscope were processed in the analysis of pulsations.

Bainar, Petr ; Kolář, Radim (referee) ; Drastich, Aleš (advisor)
The aim of the thesis is to design and implement a simulator of image reconstruction during x-ray computed tomography fluoroscopy. Apart from quantitative evaluation of particular imaging process parameters influence, the intended program application will lie in optimization of these parameter values. Introductory part is focused on brief theoretical description of x-ray computed tomography imaging process. Emphasis is placed on fluoroscopy-specific approaches, particularly the division of scanned projections into chosen amount of sectors as well as fluoroscopic imaging process evaluation methods. The subsequent part deals with program implementation and its limitations and sketches the possible working framework. Moreover, one of the chapters is devoted to optimization of imaging process parameters measurement. The final part aims at impact analysis of particular process parameters as well as fluoroscopic imaging process optimization approaches. The thesis consists also of a didactic simulator enabling real-time intervention simulation with manual instrument manipulation. Since both simulators are intended for teaching purposes, the thesis is supplemented with a laboratory exercise draft.

The subject of this diploma thesis was to process the study and the design documentation for a newly built hotel in Brno, in city district “Kníničky” near the artificial dam “Přehrada” in a rest area. The hotel will serve as temporary accommodation for up to 64 hotel guests in single, double and four bed rooms. The object also contains training rooms, offices, a meeting room, a café, a small grocery store and a restaurant with kitchen. Parking is possible in one of the two mass garages and there is an outdoor parking possibility in front of the hotel too. The building has a cast-in-place concrete frame with longitudinal beams and sway bracings. The external wall consists of aerated concrete bricks with contact thermal insulation system ETICS (insulation material mineral wool), the ceilings will be cast-in-place reinforced concrete ceilings and the roof flat green roof or flat roof with gravel on it above the 5th floor. The foundation construction consists of reinforced concrete foundation strips, which expand to foundation pads under the load-bearing columns and will be supported by piled foundations under the most exposed elements. As long as the hotel is situated into a fairly steep slope, the vertical alignment of some building parts is various so part of the project is the design of landscaping works. Design documentation was processed using the program AutoCAD 2017, the study and the visualization using both SketchUp 2015, LayOut 2015 and Lumion 5.

Non-contact detection of physiological parameters from image sequences
Bršlicová, Tereza ; Janoušek, Oto (referee) ; Kolář, Radim (advisor)
This thesis deals with the study of contactless and non-invasive methods for estimating heart and respiratory rate. Non-contact measurement involves sensing persons by using camera and the values of the physiological parameters are then assessed from the sets of image sequences by using suitable approaches. The theoretical part is devoted to description of the various methods and their implementation. The practical part describes the design and realization of the experiment for contactless detection of heart and respiratory rate. The experiment was carried out on 10 volunteers with a known heart and respiratory rate, which was covered by using of a sophisticated system BIOPAC. Processing and analysis of the measured data was conducted in software environment Matlab. Finally, results from contactless detection were compared with the reference from measurement system BIOPAC. Experiment results are statistically evaluated and discussed.

Multi-purpose Building, Jana Babaka, Brno
Kolářová, Eva ; Jelínek, Petr (referee) ; Kolář, Radim (advisor)
Project's goal is to test the large buildings' design options in regards to permanently sustainable construction. The author's aim is to design energy efficient multipurpose building, with minimal negative effects on environment. The positive impact on environment is visible on the preference of natural materials used in construction. External constructions of thermal conductivity coefficient at the level of passive standard are designed using objects of renewable energy. The location in Brno has been chosen for the proposed building, specifically the location known as brownfields. Lot is accessible from the street of Jan Babak, where public transport is available. The shape of the lot is in the form of incomplete oval with internal open atrium. The administrative part of the building takes half of the area with the rest of the area being used for other businesses, such as fitness centre and restaurant. Garages are proposed to be located underneath the main building, which is built on rigid structure. This rigid structure is a steel skeleton one with linked ceilings. The foundation of building is on stilt. The roof is of a flat type with variable slope, its structure and slope are of metal construction. Claddings are designed in the form of wooden structure filled with straw bales, the exterior is thermally insulated using fibreboard thermal insulation. Inner tract facade is proposed to be panelled with wooden planks. Photovoltaic panels will be placed both from the south and southeast of the outer oval. The rest of the facade will be panelled with grate for creepers. Only environment-friendly sources of energy are considered for the proposed building. Heating and cooling is based on the heat pump air-water system; using the rainwater as an example of renewing natural energy. The surroundings of the building are designed as meadows for of infiltration of rainwater. The proposed building has been assessed in terms of environmental sustainabilit
