Adaptive decision fusion based cooperative spectrum sensing for cognitive radio systems
(IEEE, 2011)In this paper, an online Adaptive Decision Fusion (ADF) framework is proposed for the central spectrum awareness engine of a spectrum sensor network in Cognitive Radio (CR) systems. Online learning approaches are powerful ... -
Computer vision based method for real-time fire and flame detection
(Elsevier BV, 2006-01-01)This paper proposes a novel method to detect fire and/or flames in real-time by processing the video data generated by an ordinary camera monitoring a scene. In addition to ordinary motion and color clues, flame and fire ... -
Deep convolutional generative adversarial networks for flame detection in video
(Springer, Cham, 2020)Real-time flame detection is crucial in video-based surveillance systems. We propose a vision-based method to detect flames using Deep Convolutional Generative Adversarial Neural Networks (DCGANs). Many existing supervised ... -
Diferansiyel PIR algılayıcılarla dalgacık tabanlı alev tespiti

Fire detection in infrared video using wavelet analysis
(SPIE - International Society for Optical Engineering, 2007)A novel method to detect flames in infrared (IR) video is proposed. Image regions containing flames appear as bright regions in IR video. In addition to ordinary motion and brightness clues, the flame flicker process is ... -
Fire detection in video using LMS based active learning
(Springer, 2009)In this paper, a video based algorithm for fire and flame detection is developed. In addition to ordinary motion and color clues, flame flicker is distinguished from motion of flame colored moving objects using Markov ... -
İnsan hareketlerinin vibrasyon ve PIR algılayıcıları kullanılarak sınıflandırılması
(IEEE, 2012-04)Yalnız yaşayan yaşlı ve bakıma muhtaç kişilerin yere düşmelerinin kısa sürede tespit edilmesi önemli bir sorundur. Bu bildiride, sismik ve pasif kızılberisi algılayıcılar kullanarak, belirli bir alanda yere düşme olayının ... -
Moving object detection in wavelet compressed video
(Elsevier, 2005)In many surveillance systems the video is stored in wavelet compressed form. In this paper, an algorithm for moving object and region detection in video which is compressed using a wavelet transform (WT) is developed. The ... -
Moving region detection in compressed video
(Springer, 2004)In this paper, an algorithm for moving region detection in compressed video is developed. It is assumed that the video can be compressed either using the Discrete Cosine Transform (DOT) or the Wavelet Transform (WT). The ... -
An online adaptive cooperation scheme for spectrum sensing based on a second-order statistical method
(Institute of Electrical and Electronics Engineers, 2012)Spectrum sensing is one of the most important features of cognitive radio (CR) systems. Although spectrum sensing can be performed by a single CR, it is shown in the literature that cooperative techniques, including multiple ... -
