The rapidly increasing volume of videos recorded in the course of endoscopic screenings and surgeries poses demanding challenges to video retrieval and browsing systems. Surgeons typically have to use standard video players to retrospectively review their procedures, which is an extremely cumbersome and time-consuming process. We present an HTML5-based video explorer that is specially tailored to...
Interactive navigation through a video is a simple way for a user to get a quick overview of its content and to find interesting scenes. Although common video players provide only poor navigation facilities – in comparison to real video search applications – they are often employed by users due to their simplicity. We present a tool using a similarly simple interaction method but enabling much more...
We describe a new interaction method for video navigation on touch-enabled tablet devices, which is based on previous research results and uses context-sensitive swipe gestures. We evaluate our method in a user study with known-item-search tasks in direct comparison to seeker-bar navigation that is commonly used for navigation with video players on tablets and smartphones. Our evaluation results show...
We demonstrate our novel video-based real-time traffic event notification and verification system LOOK2. It generates fast and reliable traffic information about relevant traffic state and road conditions changes on observed roads. It utilizes installed road-side sensors providing low-level traffic and environmental data, as well as video sensors which gain high-level traffic information from live...
