Die Diplomarbeit beschäftigt sich mit der Detektion von Gesichtern in Bildern. Ausgehend von einem Überblick über bestehende Verfahren wird ein viel versprechendes Verfahren ausgewählt, vorgestellt und basierend auf neuen Erkenntnissen weiterentwickelt. Bilddaten aus dem Universitätsarchiv werden exemplarisch für die Evaluierung des Verfahrens verwendet.

Head and facial injuries constitute a substantial portion of bicyclist injuries. Helmets reduce bicyclists' head and facial injuries, but not to the same extent for all injury types and locations. Current safety standards for bicycle helmets around the world, including EN1078 (Europe), CPSC 16 CFR 1203 (United States), JIS T8134 (Japan), AS/NZS 2063 (Australia and New Zealand) and GB 24429 (China), prescribe a standard test line or area for impact attenuation assessment that has limited coverage to head and face. The middle and lower part of the face, which are not protected by most existing helmet designs, are susceptible to soft tissue injuries, fractures and mandibular loading that can cause diffuse brain injury and basilar skull fracture. This study aims to quantify bicyclist head impact locations based on the Germ.an In-Depth Accident Study (GIDAS). Knowing which part of the head is impacted most frequently can inform future test method development and helmet designs beyond existing standards requirement. [from Introduction]

German talk shows enjoy great popularity among the TV audience and the most acclaimed ones can reach several million viewers each week. Talk shows are public platforms where the participants give their opinion on current events and present their ideas to a broad audience. The fact that they take place in public is of great importance. As politicians, journalists or legal experts, they do not only take part in a debate but also represent their own public image or possibly even the institutions they work for. The role they take within the discussion influences the perception of them as a person during the show and can affect their professional life outside of the talk show as well. This thesis analyses acts of verbal rejections used by participants and moderators of German TV talk shows as to how they impact the image of the recipient with regard to their role within the discussion. In accordance with the concept of face, introduced by Goffman, Brown and Levinson, this study evaluates acts of rejection according to their potential of face threatening, as well as possible revaluation for the critics own face. The analysis will draw attention to expressions used to undermine other participants’ ability to argue correctly as well as their credibility in the discussion assessing the importance of such acts in the light of the public nature of the discussion. Finally, this paper will also give view of the moderators’ role in the show, as, apart from their neutral leading position in the discussion, they too can express rejection or become victim of the participants’ criticism.
