Fusion of Procedural and Keyframe Animation
Klement, Martin ; Pečiva, Jan (referee) ; Polok, Lukáš (advisor)
The goal of this work is to create an application, which will combine procedural and keyfram animations with subsequent visualization. Composition of this two different animations techniques is used to animate a virtual character. To combine this two techniques one starts with interpolations from keyframe animation and then enchance them by procedural animations to properly fit into the characters surroundings. This procedural part of animation is obtained by using forward and inverse kinematics. Whole application is written in C++, uses GLM math library for computations and OpenGL and GLUT for final visualization.

Roughness measurement with laser profilometry
Mach, Radoslav ; Frk, Martin (referee) ; Hejátková, Edita (advisor)
The bachelor thesis deals with technology of laser profilometry for material roughness measurements purposes. The theoretical part deals with all aspects of the issue in an effective way and highlights the essential characteristics of used components and material roughness. The focus of this work is in first step to describe the external factors affecting the visual image processing such as increasing of environment temperature and its effect for a camera sensors. And particularly the relationship between CMOS and CCD technologies. The second step is for measuring roughness parameters of materials, such as metal, wood, rubber and plastic with three different lasers. Results demonstrate correlation between the wavelengths of the used laser lights with particular materials.

Design of digital camera
Miklica, Martin ; Chorý, Tomáš (referee) ; Zvonek, Miroslav (advisor)
This work deals with the history, present and future of photography. The main objective however is to design a stylish compact digital camera with regard to the requirements of modern life, such as the expansion of internet social networks and the associated use of the camera as a visual scrapbook. Emphasis was placed on a new shape solution, simple operation and good ergonomics of holding.

Procedural Animation of Human Walk
Klement, Martin ; Žák, Pavel (referee) ; Polok, Lukáš (advisor)
This thesis describes the implementation of the program displaying procedural animation of human walk. This program uses the so-called skeletal animation, in which a virtual skeleton is being moved by a forward and inverse kinematics, and subsequently the vertexes of the 3D model of a human are transformed in accordance to the skeleton. Setting of the weight of the bones for individual vertexes is done via the envelope method, the model is loaded from the "ASE" format. The application is written in the C++ programming language and for the visualization the OpenGL library with the GLUT expansion is used.

Determining Head Rotation in Video from Security Camera
Blucha, Ondřej ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
This thesis attempts to create an application to determine head rotation angle in video recorded from a security camera. The application consists of three parts: face detection, facial landmarks detection and determination of person's head rotation. The face detection has been implemented using Viola-Jones and HOG algorithms. Facial landmarks detection has been done using algorithm based on active shape model. Two methods to calculate the head rotation angles have been used: the first method works with anthropometric head features. The second method uses Perspective-n-Point algorithm to find the right rotation angles. Finally, all algorithms implemented have been tested and the proper parameters have been determined.

Denoising of Images from Electron Microscope
Holub, Zbyněk ; Kolář, Radim (referee) ; Odstrčilík, Jan (advisor)
Tato Diplomová práce je zaměřena na odstranění šumu ze snímků získaných pomocí Transmisního elektronového mikroskopu. V práci jsou popsány principy digitalizace výsledných snímků a popis jednotlivých šumových složek, které vznikají při digitalizaci snímků. Tyto nechtěné složky ovlivňují kvalitu výsledného snímku. Proto byly vybrány filtrační metody založené na minimalizaci totální variace, jejichž principy jsou v této práci popsány. Jako referenční filtrační metoda byla vybrána filtrace pomocí Non-local means filtru. Tento filtr byl vybrán, jelikož v dnešní dobře patří mezi nejvíce využívané metody, které mají vysokou účinnost. Pro objektivní hodnocení kvality filtrací byly použity tyto hodnotící kritéria – SNR, PSNR a SSIM. V závěru této práce, jsou všechny získané výsledky zobrazeny a jsou diskutovány účinnosti jednotlivých filtrační metod.
