X-ray image analysis to remove disturbing artifacts for security applications
 Schiller, Vojtěch ; Mezina, Anzhelika (referee) ; Burget, Radim (advisor)
This work deals with the issue of the decomposition of a composite X-ray image, on which both key informational and noise components are present simultaneously. The goal is to remove the present disturbing artifacts as repeating phenomena in the background using deep learning techniques while emphasizing the precise preservation of the informational components contained in the image. To achieve this, the convolutional neural network U-Net and its improved versions, which dominate especially in image segmentation, were used. Competitive models achieving excellent results at image-denoising tasks were also trained and compared. This work proposes a novel method, which was compared with the most modern architectures on the same dataset, and which, in the results, objectively and subjectively significantly surpassed all of them.

Vliv růstu ekonomiky na příjmovou nerovnost
 Schiller, Vojtěch
This diploma thesis deals with the analysis of influence of economic growth of the economies of Sweden, Great Britain and the Czech Republic on income inequality in these countries. The first part of the thesis includes the issue of income inequality, especially its factors, the measurement possibilities and the ways of solving and the consequences of income inequality. Subsequently attention is given to the determinants of economic growth and consequently on the mutual relation of the two studied quantities. Finally, the influence of selected factors on income inequality, evaluation and comparison of regression analysis results in selected economies is examined.
