This thesis explores the effects of ludic structure—defined as the elements of game play not considered content—on video game communities. Counter to the focus on video game content and its effects by other scholars, this study argues the importance of the study of game structure and its influences on player interactions. Two games, League of Legends and Puzzle Pirates were examined. I played both games for 20 hours, as well as interviewing four players from each game. Using Laura Ellingson’s (2009) crystallization as a guiding approach, I analyzed the games using both a traditional thematic analysis and personal narratives in an attempt to create a richer dataset from which to draw conclusions. I discovered that one game was more competitively structured (League of Legends), which resulted in more aggressive and negative interactions among players in the community. Puzzle Pirates, on the other hand was more cooperatively structured, which resulted in an open and friendly community of people who were wanting to help each other. I argue that ludic structure does have a significant impact on player interactions, and that game companies should strive for more cooperatively structured games to encourage a positive community of gamers. / Literature review -- Methodology -- Close analysis of League of legends -- Close analysis of Puzzle pirates -- Conclusions, flaws and future research. / Department of Communication Studies

The thesis represents the research in the domain of modern video tracking systems and presents the details of the implementation of such a system. Video surveillance is a high point of interest and it relies on robust systems that interconnect several critical modules: data acquisition, data processing, background modeling, foreground detection and multiple object tracking. The present work analyzes different state of the art methods that are suitable for each module. The emphasis of the thesis is on the background subtraction stage, as the final accuracy and performance of the person tracking dramatically dependent on it. The experimental results show the performance of four different foreground detection algorithms, including two variations of self-organizing feature maps for background modeling, a machine learning technique. The undertaken work provides a comprehensive view of the actual state of the research in the foreground detection field and multiple object tracking and offers solution for common problems that occur when tracking in complex scenes. The chosen data set for experiments covers extremely different and complex scenes (outdoor environments) that allow a detailed study of the appropriate approaches and emphasize the weaknesses and strengths of each algorithm. The proposed system handles problems like: dynamic backgrounds, illumination changes, camouflage, cast shadows, frequent occlusions and crowded scenes. The tracking obtains a maximum Multiple Object Tracking Accuracy of 92,5% for the standard video sequence MWT and a minimum of 32,3% for an extremely difficult sequence that challenges every method.
