Anomaly detection with sparse unmixing and gaussian mixture modeling of hyperspectral images
(Bilkent University, 2015-07)One of the main applications of hyperspectral image analysis is anomaly detection where the problem of interest is the detection of small rare objects that stand out from their surroundings. A common approach to anomaly ... -
A comparative study on human activity classification with miniature inertial and magnetic sensors
(Bilkent University, 2011)This study provides a comparative assessment on the different techniques of classifying human activities that are performed using body-worn miniature inertial and magnetic sensors. The classification techniques compared ... -
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 ... -
Maximum likelihood estimation of Gaussian mixture models using particle swarm optimization
(IEEE, 2010-08)We present solutions to two problems that prevent the effective use of population-based algorithms in clustering problems. The first solution presents a new representation for arbitrary covariance matrices that allows ... -
Pulse doppler radar target recognition using a two-stage SVM procedure
(IEEE, 2010-07-07)It is possible to detect and classify moving and stationary targets using ground surveillance pulse-Doppler radars (PDRs). A two-stage support vector machine (SVM) based target classification scheme is described here. The ... -
Source and filter estimation for Throat-Microphone speech enhancement
(Institute of Electrical and Electronics Engineers Inc., 2016)In this paper, we propose a new statistical enhancement system for throat microphone recordings through source and filter separation. Throat microphones (TM) are skin-attached piezoelectric sensors that can capture speech ...
