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.

Robotic Table Football
Jediný, Lukáš ; Zuth, Daniel (referee) ; Lang, Stanislav (advisor)
The focus of this thesis is design and production of a robotic table football. The aim of the thesis is to select a camera and a lens and to devise lighting. The data from the camera require proper processing to assess the location of the ball, based on which the game algorithm controls the movement of the robotic players. Inherent part of the thesis is testing the player control algorithm using a simple simulation.

Lens Distortion Correction
Doležel, Michal ; Seeman, Michal (referee) ; Šiler, Ondřej (advisor)
The bachelor thesis deals with methods of removing digital photographies aberrations caused by photographical lens distortions. It describes the most frequent lens aberrations, deals with their causes, followed by consequences of these aberrations on destination pictures and ways of their removing from digital photographies. The main goal of the thesis is to design and implement tools for removing lens distortions aberrations from a digital photography. The application was created in C++ programming language with the support of Cimg and Imagemagick libraries. The application was also developed and tested for MS Windows XP and Linux Kubuntu 7.10 operation systems. The results are compared with professional tools for digital photography processing.

Evaluation of optical components for LED
Dobiáš, Jiří ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
This thesis deals with an evaluation of optical components for LED, which is based on laboratory measurements of available LED samples and optical elements. The evaluation is done according to established standards and is focused on efficiency and adjustment of luminous flux (beam angle, luminous curve). Furthermore was made a study engaged in an optical element influence on LED color properties (color temperature, spectral characteristics). In conclusion there is an optical elements usage overview and recommended procedure for selecting appropriate combination of LED and optical element.

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...

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.
