Numerical characteristics of digital image quality
Ivičič, Vojtěch ; Martišek, Dalibor (referee) ; Druckmüller, Miloslav (advisor)
This thesis deals with quality of digital images and with methods for measurement their numerical characteristics. Our attention is drawn to measurement of sharpness, as a main factor of image quality, in both space and spectral domain. For this reason, the Fourier and the discrete Fourier transform is described in one and two dimensions. Methods, presented in this work and implemented on attached CD, can be used for automatic image quality classification and autofocus of optical systems.

Fundamentals of quadratic fields
Ivičič, Vojtěch ; Karásek, Jiří (referee) ; Skula, Ladislav (advisor)
The aim of the thesis is to describe the fundamentals of quadratic fields. In the first part integer and polynomial arithmetic is mentioned. The main part discusses the topic of quadratic field, quadratic integer, Gaussian field and Gaussian integer. The final part deals with quadratic fields without unique factorization and a solution of the problem through ideals.
