Comparison of Time-Dependent Color-to-Gray Conversions
Vlkovič, Vladimír ; Hradiš, Michal (referee) ; Čadík, Martin (advisor)
This masters thesis is focused around the comparison of time dependent video grayscale conversion methods based on a user experiment. The test methodology is based on the pairwise comparison method 2AFC. It is composed of two test variants: a test with a reference video and a test without a reference video. The coefficients of agreement, consistency and correlation are utilized in the result analysis. The testing was done on 60 subjects which have done 7200 pairwise comparisons. The test results show that the time dependent method Hu14 is the most universal. Time dependent method Kim09 was bested by some non-dependent methods. The results also indicate that there is some correlation between the two test variants and that the choice of the input video can have impact on the method performance. The main contribution of this thesis is that non-dependent methods can under certain circumstances rival the performance of dependent methods and that the addition of a reference video did not have a meaningful impact on the test subjects judgements.

Marketing mix of fitness center FreshKruháč during the pandemic situation
Pavelková, Simona ; Opelík, Daniel (advisor) ; Voráček, Josef (referee)
Title: Marketing mix of fitness center FreshKruháč during the pandemic situation Objectives: The main goal of this bachelor's thesis is to propose recommendations to improve operation of the fitness center FreshKruháč in crisis situation. Recommendations will be based on evaluation of individual tools of the marketing mix and on the identification of problematic areas during pandemic. Methods: The evaluation of the marketing mix was carried out by analysing the center's website and social networks. In addition, the interview was conducted with the center's management to identify information that was not traceable and to compile a list of strengths and weaknesses. The last method used was pairwise comparison, which determines the importance of the center's weaknesses and strengths during the pandemic. Results: Based on the evaluated marketing mix, a list of strengths and weaknesses was developed with the management of the center. The determination of their importance by means of a pairwise comparison method, which was carried out by the staff of the selected fitness centre, served as a basis for suggestions for improvement. The recommendations serve to make the centre more effective in the next potential crisis situation. On the contrary, the summary of the most important strengths provides...
