Active authentication is the process of continuously verifying a user based on his/her ongoing interaction with the computer. Forensic stylometry is the study of linguistic style, applied to author (user) identification. We evaluate the Active Linguistic Authentication Dataset [Juola et al., 2013], collected from users working individually in an office environment for a period of one week. We c...

We present a real-time cooperative multi-target tracking system. The system consists of a group of Active Vision Agents (AVAs), where an AVA is a logical model of a network-connected computer with an active camera. All AVAs cooperatively track their target objects by dynamically exchanging object information with each other. In this paper, we address the technologies employed in the system and ...

This paper presents a novel, agent-based sensing-system reconfiguration methodology for the recognition of time-varying-geometry targets (objects or subjects). A multi-camera activevision system is used to improve form-recognition performance by selecting near-optimal viewpoints along a prediction time horizon. The proposed method seeks to maximize the target visibility in a cluttered, dynamic ...

aging is a crucial period in human life and it is a social necessity to pay attention to the issues and needs of this stage of life. the aim of the current study was to study the effect of body mass index (bmi) on reaction time and response time of the active and inactive elderly. the research method was causal-comparative and its statistical population consisted of the elderly from mahabad cit...
