Comparison of terahertz technologies for detection and identification of explosives
(SPIE, 2014)We present results on the comparison of different THz technologies for the detection and identification of a variety of explosives from our laboratory tests that were carried out in the framework of NATO SET-193 THz ... -
Convexity properties of detection probability under additive Gaussian noise: optimal signaling and jamming strategies
(IEEE, 2013)In this correspondence, we study the convexity properties for the problem of detecting the presence of a signal emitted from a power constrained transmitter in the presence of additive Gaussian noise under the Neyman-Pearson ... -
Directional processing of ultrasonic arc maps and its comparison with existing techniques
(2007)Directional maximum (DM) technique for processing ultrasonic arc maps (UAMs) is proposed and compared to existing techniques. It employs directional processing in extracting the map of the environment from UAMs. DM aims ... -
Efficient algorithm to extract components of a composite signal
(IEEE (Institute of Electrical and Electronics Engineers), 2000)An efficient algorithm is proposed to extract components of a composite signal. The proposed approach has two stages of processing in which the time-frequency supports of the individual signal components are identified and ... -
An empirical eigenvalue-threshold test for sparsity level estimation from compressed measurements
(European Signal Processing Conference, EUSIPCO, 2014)Compressed sensing allows for a significant reduction of the number of measurements when the signal of interest is of a sparse nature. Most computationally efficient algorithms for signal recovery rely on some knowledge ... -
Error resilient layered stereoscopic video streaming
(2007)In this paper, error resilient stereoscopic video streaming problem is addressed. Two different Forward Error Correction (FEC) codes namely Systematic LT and RS codes are utilized to protect the stereoscopic video data ... -
Eye tracking using markov models
(2004)We propose an eye detection and tracking method based on color and geometrical features of the human face using a monocular camera. In this method a decision is made on whether the eyes are closed or not and, using a Markov ... -
A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
(Hindawi Publishing Corporation, 2006)Focusing on transmit diversity orthogonal frequency-division multiplexing (OFDM) transmission through frequency-selective channels, this paper pursues a channel estimation approach in time domain for both space-frequency ... -
Noise enhancement in joint detection and estimation systems
(IEEE Computer Society, 2014)Adding noise to inputs of some suboptimal detectors or estimators can improve their performance under certain conditions. In this study, a noise enhanced joint detection and estimation system is investigated. Maximization ... -
Optimal detector randomization for multiuser communications systems
(IEEE, 2013)Optimal detector randomization is studied for the downlink of a multiuser communications system, in which users can perform time-sharing among multiple detectors. A formulation is provided to obtain optimal signal amplitudes, ... -
Optimal stochastic signal design and detector randomization in the neyman-pearson framework
(2012)Power constrained on-off keying communications systems are investigated in the presence of stochastic signaling and detector randomization. The joint optimal design of decision rules, stochastic signals, and detector ... -
QR-RLS algorithm for error diffusion of color images
(SPIE, 2000)Printing color images on color printers and displaying them on computer monitors requires a significant reduction of physically distinct colors, which causes degradation in image quality. An efficient method to improve the ... -
Spectrum sensing via restricted neyman-pearson approach in the presence of non-Gaussian noise
(2013)In this paper, spectrum sensing in cognitive radio systems is studied for non-Gaussian channels in the presence of prior distribution uncertainty. In most practical cases, some amount of prior information about signals of ... -
What is usual in unusual videos? trajectory snippet histograms for discovering unusualness
(IEEE Computer Society, 2014)Unusual events are important as being possible indicators of undesired consequences. Moreover, unusualness in everyday life activities may also be amusing to watch as proven by the popularity of such videos shared in social ...
