Applications of wavelet transform in Mathematica and Sage
Novotný, Radek ; Trzos, Michal (referee) ; Rajmic, Pavel (advisor)
This thesis focuses on image processing using wavelet transform. The usage of wavelet transform is analysed especially for image compression and image noise reduction purposes. The analysis describes in detail aspects and application of the following wavelet transform methods: CWT, DWT, DTWT, 2D DWT. The thesis further explains the meaning of the mother wavelet and studies certain specific kinds of wavelets, kinds of thresholding and its purposes and also touches on the JPEG2000 standard. Mathematica and Sage software packages were used to design algorithms for image compression and image noise reduction, utilising relevant wavelet transform findings. The concluding part of the thesis compares the two software packages and results obtained using different algorithms.

Code Generator for RedDeer Test Framework
Jelínek, Dominik ; Bečková, Zuzana (referee) ; Číka, Petr (advisor)
This bachelor’s thesis describes the design and creation of a new Eclipse plug-in. The theoretical part of the thesis describes the architecture of the Eclipse development environment, discusses Java graphical libraries and explains options for extending the Eclipse development environment through its own new plug-ins. Next part of the thesis describes types of application testing and presents ways of application compiling. Practical part of the thesis explains the development of a plug-in, details of internal logic for code generating and describes the implementation of the designed solution for the code generator for the RedDeer Test Framework.

Comparison of fatigue fracture criteria for torsion
Roh, Marek ; Slámečka, Karel (referee) ; Horníková, Jana (advisor)
The main goal of this bachelor thesis is to determine which criteria better suits the life prediction of the test sample loaded in the pulsating torsion. In the first part of this thesis fatigue failure will be examined, then fluctuating stresses will be characterized along with shear stress. Characteristics of the materials used will be specified in the second part. Lastly, the most appropriate criteria will be determined.

Automatic Text Recognition for Robots
Hartman, Zdeněk ; Materna, Zdeněk (referee) ; Španěl, Michal (advisor)
This bachelor thesis describe module design for text detection and recognition for use in robotic systems. To detect charters is used Stroke Width transform, which is applied on the input edge image. In the output image after Stroke Width transform are found connected components. For letter grouping into a words is used Hough transform, which is applied on the created binary image. This image contains points, which corresponding positions of found connected components. To recognize signs in detected areas is used Tesseract library. Before recognition detected areas are extracted and rotated into a horizontal position. This proposed detector can detect even rotated text. Accuracy of detection of the text is 75% above the test set "informační tabule".

Profiling Perspective in Eclipse
Hynek, Jiří ; Přikryl, Zdeněk (referee) ; Hruška, Tomáš (advisor)
This bachelor's thesis is concerned by question of creation a new plug-in for software development enviroment Eclipse. Product of this work is the view intended for profiling perspective of software development enviroment of project Lissom based on Eclipse. The aim of the view is draw call graphs defined by data from XML structure.
