Software for cameras configuration design of the panoramic system
Jílek, Michal ; Grenar, David (referee) ; Kříž, Petr (advisor)
This work deals with software design in C ++ language and with graphical output using OpenGL for scanning tribune lenses of cameras with different parameters so that the user lens configurations are known beforehand in order to create panoramic coverage of the stadium stadium. The principle of image capture, lens parameters, and formulas for calculating their appropriate layout on the stadium to collect a panoramic image together is discussed. These are: focal length, viewing angles, coverage calculations, image resolution. Furthermore, a draft program implementing the issue.

Characterization of mice with constitutively active Wnt/beta-catenin signaling pathway in lens
Antošová, Barbora ; Kozmik, Zbyněk (advisor) ; Pavlínková, Gabriela (referee)
Lens development and differentiation are strictly regulated processes. Various disturbances of these processes can lead to vision-limiting pathologies. The vertebrate lens is composed of epithelial cells and terminally differentiated fiber cells. Differentiation of fiber cells is connected with expression of fiber cell specific proteins (such as crystallins), cell cycle exit, and finally with the degradation of cell nucleus and organelles. Wnt/β-catenin signaling plays important roles during early eye development as well as later during the lens differentiation. To investigate the consequences of constitutive activation of Wnt/β-catenin signaling in lens fiber cells transgenic mouse strain, called CLEF, was created. Constitutive activation of Wnt/β-catenin signaling in fiber cells of CLEF mouse is achieved by transgenic protein CLEF that contains C-terminal activation domain of β-catenin fused to the amino terminus of full-length protein Lef1. The expression of CLEF transgene is under the control of αA-crystallin promoter. As a result of constitutive activation of Wnt/β-catenin signaling in fiber cells, adult CLEF mice develop cataracts and microphthalmia, and the morphology of adult mutant lenses is disrupted. Transgenic CLEF mRNA is expressed starting from E13.5 and by E16.5 transgenic CLEF protein is...

Procedurally Generated Lens Flare Effect for Blender
Volf, Petr ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
Lens flare is an image artefact caused by unintended reflection of light in camera's lens system. The goal of this project is simulation of this phenomena in open source 3D content creation suite Blender. The generated effect is then composited into final image. The project is designed as an add-on. The add-on allows user to customize several parameters to achieve the desired result.

Product quality control
Pitrun, Tomáš ; Janáková, Ilona (referee) ; Boštík, Ondřej (advisor)
The bachelor’s thesis deals with the industrial inspection of defects on injection molding based on computer recognition. Part of the work is a description of injection molding technology and defects that may occur with this technology. The detection application is implemented in Python on the Raspberry Pi platform. The OpenCV library is used to detect product defects. Part of the work is also the selection of suitable hardware resources, including the Raspberry Pi microcomputer, lighting camera module, lens, relay modules and supporting structure.

Virtual Reality Lens Image Distortion Correction
Procházka, Tomáš ; Wilkie, Alexander (advisor) ; Horáček, Jan (referee)
Lenses in virtual reality headsets make it possible to put displays close to users' eyes and they provide users with wider field of view. However, they also distort the displayed image. Providing we know the lens distortion properties, it is possible to compensate for the distortion by displaying an image that is distorted in the opposite way. This thesis focuses on measurement of the distortion for an arbitrarily complex lens, while also considering chromatic aberration. A system capable of measuring of the distortion using just a camera attached to the virtual reality headset is designed and implemented. It is based on pattern detection and comparison of relative positions of points on the display and their correspondences in the distorted image. The result is a 2D distortion map that can be used to transform images such that they appear undistorted to the virtual reality headset users.

Evaluation of functional properties of selected vegetable flours
VÍTKOVÁ, Věra
This bachelor thesis deals with basic structure, nutritional properties, production and use of flours. There are information about cereals and legumes, which are used for productions of flours. This thesis talks about food intolerances, which can be a reason why change basic flours of wheat, barley, oat and rye to another. Practical part is about 14 flours, which were tested on dry matter, humidity, nitrogen substances content, proteins, protein electrophoretic profiles (patterns), solubility, water and fat holding capacity, formation of gels and changes of colours during a boiling. The results of this research are information about nutrition and functional properties of tested flours.

Machine vision for locating objects
Hasík, Dávid ; Huzlík, Rostislav (referee) ; Vetiška, Jan (advisor)
The bachelor’s thesis deals with design of machine vision system for object localization and its application possibilities. Design approach, its components and their individual advantages and disadvantages for this type of machine vision system are described. This thesis also includes simple model of machine vision system for object localization using regular PC. For image processing is used Vision Assistant and its tools. Two scripts are made in this software and their performance is compared.

VC5 and Vision Designer platform visual system
Popovský, Pavel ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
For the purpose of an future machine vision system development in Tyco Electronics Czech s.r.o. I have developed Cognex Designer template. Template will serve as a flexible basis for further development of camera applications on the Cognex VC5 industrial computer. The functionality of the program template has been successfully verified by modifying it to a particular application of the laboratory manual station used to measure the parameters of the manufactured connectors. A camera with lens and lightning was chosen and installed on the station. DIO communication was put into operation between VC5 and PLC system. The application has been calibrated and verified as a measurement system using MSA Type I and Capability study standard methods.
