Tracking and identifying persons in videos are important building blocks in many applications. For interactive investigation of surveillance footage it is often not even necessary to uniquely identify a person. It rather suffices to find occurrences of a person indicated by the user with an exemplary image sequence. We present a system in which the search for a specific person can be initiated ...

In a work of Just, Miller, Scheepers and Szeptycki it was asked whether certain diagonalization properties for sequences of open covers are provably closed under taking finite or countable unions. In a recent work, Scheepers proved that one of the properties in question is closed under taking countable unions. After surveying the known results, we show that none of the remaining classes is prov...

In this paper, an outdoor multi-camera video surveillance system operating under changing weather conditions is presented. A new confidence measure, Appearance Ratio (AR), is defined to automatically evaluate the sensors’ performance for each time instant. By comparing their ARs, the system can select the most appropriate cameras to perform specific tasks. When redundant measurements are availa...

This paper explores in which ways privacy (in particular, data protection principles) comes to the fore in the day-to-day operation of a public video surveillance system. Starting from current European legal perspectives on data protection, and building on an empirical case study, the meanings and management of privacy in the practice of Closed-Circuit Television (CCTV) will be discussed in ord...

This study aimed at investigating the impact of closed-caption program on listening comprehension of English movies and vocabulary learning. Sixty-four graduate students studying at Shiraz Islamic Azad University were selected as the participants of the study. The participants were divided into two groups: experimental group (with closed caption program) and control group (without closed captio...

closed-end furrows are commonly used to irrigate crop in northern part of china. the irrigation performance of furrow in this area is often low. the objectives of this paper are to verify reliability of infiltration parameters and manning roughness estimated with sipar_id software and present an optimized method for design of closed-end furrow system. the study consisted of field experiments an...

background endotracheal suctioning is a necessary procedure practiced by nurses in intensive care units to remove lung secretions. this procedure leads to higher oxygenation levels and reduced breathing difficulties. it also prevents atelectasis, pulmonary infections, and the accumulation of secretions. objectives the present study aims to compare the effectiveness of open and closed endotrache...
