Analysis and visualization of a social network
Kudělka, Miloš ; Mráz, František (advisor) ; Skopal, Tomáš (referee)
The present work starts with study of past and current methods from the field of analysis and visualization of social networks. Selected methods are then described in detail. Following part is devoted to research of current software. Selected applications are tested and evaluated according to their capability of showing a development in dynamic social networks -- networks with temporal data. Based on these researches an application is designed and implemented. This application can be used for analysis and visualization of a development of dynamic networks in time. Finally, the application is tested on co-authorship social network by means of the bibliographic database of scientific papers DBLP. The work also presents the results of the experiments with implemented algorithms.

3D Computer Vision on the Android Platform
Vášová, Viktorie ; Mach, Lukáš (advisor) ; Kudělka, Miloš (referee)
The aim of this work is to study the problem of automatically reconstructing a 3D scene from a pair of its photographs. It investigates to what extent can this task be performed on a mobile phone running on the Android platform. Several image correspondence algorithms are discussed. The specifics of the Android platform from developers perspective are also considered. The algorithms are then utilized in a particular way to obtain a mobile software solution for 3D reconstruction. This software runs solely on a mobile phone, including capturing the photos by the phone's camera and the final visualization. An implementation of the application is a part of this work.

Evaluation function for Atari-go
Kudělka, Miloš ; Hric, Jan (advisor) ; Majerech, Vladan (referee)
The present work describes a design and an implementation of Atari Go computer game. This includes an implementation of mini-max and mini-max with alpha-beta pruning algorithms for searching for the best moves. Additionally, the work describes the design and the implementation of an evaluation function and the selection of suitable criteria of the position. This function then can evaluate the position by evaluating these criteria. Further on, the work demonstrates one style of improving the parameters of evaluation function - simple learning algorithm is designed, applied to this problem and implemented. This algorithm improves the parameters by playing games. The results of improvings are presented in the work, too.

Image Quality Assessment
Kudělka, Miloš
Image quality assessment is a difficult problem in the field of image processing without any acceptable solution yet. Quality assessment of textures, which is the topic of this work, is even harder problem. This work presents an overview and a description of current state of the art methods as well as brief experiments on textures and a discussion about the usability of these methods on textures.
