Image Transformations
Novák, Radim ; Juránek, Roman (referee) ; Venera, Jiří (advisor)
The main goal of this thesis is to introduce two fundamental geometric transformations in 2D space - by changing the resolution together with related image resampling and image rotation. Also brightness interpolation, technique of mapping and other problems related to the topic are explained there, i.e. Fourier transformations, problem with aliasing and technique of aliasing suppression.

Geometrical Image Transforms
Havelka, Jan ; Švub, Miroslav (referee) ; Španěl, Michal (advisor)
This bachelor's thesis is about introducing to basics of image processing, mostly with linear image transformations and interpolation. For the purpose of the closer understanding is properly to implement some basic geometrical image transformations and some different interpolation methods.

System for Management of Photographic Collections
Faika, Petr ; Kučiš, Michal (referee) ; Zemčík, Pavel (advisor)
Primary objective of my thesis is the choice, suggestion and implementation of a feature to manage a collection of photos. The current status regarding photography collection is described as well as two existing sotware for that purpose. Description of a photo file, choice of features, suggestion and implementation description follows. I've chosen the feature to merge photos from multiple cameras. At the end of the thesis there's a proof of results and discussion about further extension options.

Geometrical Image Transforms
Němeček, Petr ; Řezníček, Ivo (referee) ; Španěl, Michal (advisor)
This master's thesis deals with acceleration of geometrical image transforms using the GPU and NVIDIA (R) CUDA TM architecture. Time critical parts of the code are moved on the GPU and executed in parallel. One of the results is a demonstrational application for performance comparison of both architectures: the CPU, and GPU in combination with the CPU. As a reference implementation, there are used highly optimized routines from the OpenCV library, made by the Intel company.

3D Photo Slideshow Using OpenGL
Ondrejíček, Marián ; Navrátil, Jan (referee) ; Seeman, Michal (advisor)
The aim of this thesis was to design a photo slideshow in 3D space using OpenGL and to implement functional application. Also there is description of Qt toolkit, which was used to design graphical user interface of the program. Furthermore there are explained basics of quaternion interpolation, which is the core of animation and camera system. The second part describes practical realization and each part of the project in details. Application was successfully implemented. In the end, the results are discussed, including possibilities of future development.

Influence of rotating wheels on vehicle aerodynamic characteristics
Oslizlo, Aleš ; Svída, David (referee) ; Vančura, Jan (advisor)
The diploma thesis is focused on computational examination of influence of boundary condition settings in CFD software on the final aerodynamic characteristics of a vehicle. The flow analysis is carried out around a vehicle with and without the rotation of the wheels and along with the stationary and moving road. Furthermore, there is demonstrated the method of the CFD model composition and there is described the influence of rotating wheels on vehicle aerodynamic characteristics.

Flight statements electronic sensor.
Harant, Josef ; Fedra, Zbyněk (referee) ; Šebesta, Jiří (advisor)
This diploma thesis deals with theoretical analysis, design and practical solution of flight statements electronic sensor. This device is primarily intended for measuring telemetry data during aerobatic flights. Theoretical part contains fundamentals of GPS and inertial navigation systems. Design of the device is divided into three parts - design of block structure, construction and software for the measuring device. The final realization is made with respect to minimal system requirements and to possible future extensibility for wider usage spectrum.

Lie groups theory in robotics
Horník, Petr ; Vašík, Petr (referee) ; Hrdina, Jaroslav (advisor)
In this thesis we focus on the mathematical description of the forward kinematics in three-dimensional space using orthogonal transformations and matrix theory. Applying the acquired knowledge we solve an example using the method of moving frame. Between bases we pass using the passage matrix and we implement the example in the MATLAB environment. Consequently, we focus on deeper relation with exponential functions and extend the theory by the theory of Lie groups and algebras. Especially, we take notice of the special orthogonal group SO(3). Finally, we enrich the theory with homogeneous transformation and special Euclidean group.

Rotational angiography
JAŠAROVÁ, Eva
Digital Subtraction Angiography (DSA) is a special X-ray examination of the blood vessel system. Despite the development of other visual techniques it has not lost its importance so far. In the 1960s and 1970s it developed itself into the most detailed method of visualization of the blood-vessel system. DSA requires much more expensive device and equipment with tools than only ten years ago. The price is equal to the quality and amount of information. DSA further remains the invasive method. One or two-projection system for acquiring the complete picture of blood vessels is the most used technique of record in angiography. Common methodologies require two applications of the contrast medium for the same part of the body. Rotation angiography is a special modern technique for three-dimensional visualization of arteries. It is mainly used for visualization of neck or brain arteries. Its principle is in the application of the contrast medium into the artery, when the examined area is X-rayed and C-arm is continuously turned by 180°. The final angiography can be assessed that we turn the picture step by step. If we display the same area once more without the application of the contrast medium, we get a mask for DSA and both sequences we can subtract. Only one artery is displayed as well as during classic DSA.
