Covariance matrix-based fire and flame detection method in video
(Springer, 2011-09-17)This paper proposes a video-based fire detection system which uses color, spatial and temporal information. The system divides the video into spatio-temporal blocks and uses covariance-based features extracted from these ... -
Online minimax optimal density estimation and anomaly detection in nonstationary environments
(Bilkent University, 2017-08)Online anomaly detection has attracted signi cant attention in recent years due to its applications in network monitoring, cybersecurity, surveillance and sensor failure. To this end, we introduce an algorithm that ... -
Optimal pattern of technology adoptions under embodiment: a multi-stage optimal control approach
(John Wiley & Sons Ltd., 2011)By deriving the necessary conditions for a multi-stage optimal control problem where the endogenous switching instants appear as an argument of the state equation, we analyze the optimal pattern of technology adoptions ... -
Shifting network tomography toward a practical goal
(ACM, 2011)Boolean Inference makes it possible to observe the congestion status of end-to-end paths and infer, from that, the congestion status of individual network links. In principle, this can be a powerful monitoring tool, in ...
