Rubik's Cube augmented reality helper application
Španěl, Martin ; Kamenický, Jan (advisor) ; Kotera, Jan (referee)
The program introduced in this thesis assists with solving a Rubik's cube using computer vision and augmented reality. The assistance consists of two phases - in the first phase the state of the cube is recognized. In the second phase the next turn to make is shown until the cube is solved. Both of these phases do not need any other input from the user other than the data from the camera. The user can show the faces of the cube in arbitrary order and from arbitrary angle. During the solving phase the cube can be held in any orientation. Powered by TCPDF (www.tcpdf.org)
Factors in attitude changes: base for environmental education
Kotěra, Jan ; Lorenzová, Jitka (advisor) ; Valenta, Josef (referee)
The thesis addresses attitude changes towards environmental problems. It looks for the factors that affect the attitude change and compares their importance. With regard to particular factors it suggests how to work more efficiently on changing the attitudes. The theoretical part gives an overview of environmental education. It follows its history in the Czech Republic and abroad, and describes its current objectives, topics and methods. It also discusses today's Czech public perception of environmental issues. The key chapter of the thesis addresses attitudes. It describes their formation, structure and basic functions and most importantly the circumstances under which they may change. With the help of literature, it defines eight fundamental factors that act to attitude change, and finds examples in environmental education. At the end of the theoretical part, recommendations are offered on what tools we should focus when trying to change attitudes. The research part presents the inquiry among selected environmental education centres' staff. It figures out how they work with the issue of attitude changes and how they take advantage of their clients' feedback. In the first place, it uses their experience to find the most important factors in attitude changes . The conclusion compares the findings...
Variational methods for segmentation of digital images
Kotera, Jan
The text covers the theory of the Mumford and Shah model for digital image segmentation. The strong and weak formulation is presented and the questions of existence, uniqueness, and solution regularity is answered. Then, a particular variant of the model called `active contours without edges' is numerically implemented. This implementation is tested on several images, the results are presented in detail and theoretically explained. Powered by TCPDF (www.tcpdf.org)
