Pupil Detection

Pupil center and pupil contour are two of the most important features in the eye-image used for video-based eye-tracking. Well annotated databases are needed in order to allow benchmarking of the available- and new pupil detection and gaze estimation algorithms. Unfortunately, creation of such a data set is costly and requires a lot of efforts, including manual work of the annotators. In addition, reliability of manual annotations is hard to establish with a low number of annotators. In order to facilitate progress of the gaze tracking algorithm research, we created an online pupil annotation tool that engages many users to interact through gamification and allows utilization of the crowd power to create reliable annotations \cite{artstein2005bias}. We describe the tool and the mechanisms employed, and report results on the annotation of a publicly available data set. Finally, we demonstrate an example utilization of the new high-quality annotation on a comparison of two state-of-the-art pupil center algorithms.

Abstract The techniques of performing a tracheostomy has transformed over time. Percutaneous tracheostomy is gaining popularity over open tracheostomy given its advantages and as a result the number of bedside tracheostomies has increased necessitating the need for a Percutaneous Tracheostomy Program. The Percutaneous Tracheostomy Program at the Johns Hopkins Hospital is a comprehensive service that provides care to patients before, during, and after a tracheostomy with a multidisciplinary approach aimed at decreasing complications. Education is provided to patients, families, and health-care professionals who are involved in the management of a tracheostomy. Ongoing prospective data collection serves as a tool for Quality Assurance.

In dieser Studie zur Qualitätssicherung in der Prophylaxe und Therapie des Dekubitus durch Auflagedruckmessungen bei Probanden auf sechs Weichlagerungs- und fünf Wechseldrucksystemen war die Zielsetzung, eine Ist-Analyse der am Klinikum eingesetzten Antidekubitushilfsmittel durchzuführen. Außerdem galt es herauszufinden, ob die angewandte Methode der pneumatischen Druckmessung mit Probanden auch im Versorgungsalltag verwendbar ist. Können verlässliche und valide Messdaten erwartet werden, wenn man bei betroffenen Patienten Messungen durchführt? Zur Beantwortung dieser Fragen wurden bei 23/19 Probanden, auch in Seitenlage, durch das Platzieren von Messmatten zwischen Körper und unterschiedliche Antidekubitussysteme Messungen durchgeführt. Bei den Weichlagerungssystemen kann an allen Messorten eine signifikante Druckreduzierung (p < 0,05), am Os coccygis eine hochsignifikante Druckreduzierung (p < 0,01) nachgewiesen werden. Bei den Wechseldrucksystemen liegt der Mittelwert der maximalen Druckbelastung über 12 min bei unterschiedlicher Amplitude (75,47 mmHg–5 mmHg) und verschiedener Frequenz (1,5 min–10 min) zwischen 56,39 mmHg und 38,94 mmHg.
