Application for Processing of a Photographed Text
Genčúr, Martin ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This work introduces main approches for converting a photographed text into black and white form. It analyses particular methods being used for this task. Following part describes implementation of the application performing a conversion. The program is tested with suitable data (coloured picture, a picture with various shades etc.) and illustrates the usability of the application. The thesis also contains an introduction to optical character recognition (OCR) and suggests potential ways of development of this application.

Analysis of 3D CT image data aimed at detection and classification of specific tissue structures
Šalplachta, Jakub ; Malínský, Miloš (referee) ; Jan, Jiří (advisor)
This thesis deals with the segmentation and classification of paraspinal muscle and subcutaneous adipose tissue in 3D CT image data in order to use them subsequently as internal calibration phantoms to measure bone mineral density of a vertebrae. Chosen methods were tested and afterwards evaluated in terms of correctness of the classification and total functionality for subsequent BMD value calculation. Algorithms were tested in programming environment Matlab® on created patient database which contains lumbar spines of twelve patients. Following sections of this thesis contain theoretical research of the issue of measuring bone mineral density, segmentation and classification methods and description of practical part of this work.

Application for Processing of a Photographed Text
Hotař, Roman ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This work describes conversion methods of full-colour picture with text ( colour transition, various shades etc. ) into black and white form. It focuses mainly on adaptive thresholding. Mentions used data structures and describes interface of result application. The thesis describe at the conclusion the results of several functionality tests.
