A confidence ellipsoid approach for measurement cost minimization under Gaussian noise
(IEEE, 2012-06)The well-known problem of estimating an unknown deterministic parameter vector over a linear system subject to additive Gaussian noise is studied from the perspective of minimizing total sensor measurement cost under a ... -
Convexity properties of outage probability under Rayleigh fading
(IEEE, 2012)In this paper, convexity properties of outage probability are investigated under Rayleigh fading for an average power-constrained communications system that employs maximal-ratio combining (MRC) at the receiver. By studying ... -
Detection of empty hazelnuts from fully developed nuts by impact acoustics
(IEEE, 2005)Shell-kernel weight ratio is the main determinate of quality and price of hazelnuts. Empty hazelnuts and nuts containing undeveloped kernels may also contain mycotoxin producing molds, which can cause cancer. A prototype ... -
Human face detection in video using edge projections
(SPIE, 2006)In this paper, a human face detection method in images and video is presented. After determining possible face candidate regions using color information, each region is filtered by a high-pass filter of a wavelet transform. ... -
Optimal stochastic approaches for signal detection and estimation under inequality constraints
(Bilkent University, 2012)Fundamental to the study of signal detection and estimation is the design of optimal procedures that operate on the noisy observations of some random phenomenon. For detection problems, the aim is to decide among a number ... -
Optimal stochastic signal design and detector randomization in the Neyman-Pearson framework
(IEEE, 2012-03)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 ... -
Signal and image processing algorithms for agricultural applications
(Bilkent University, 2006)Medical studies indicate that acrylamide causes cancer in animals and certain doses of acrylamide are toxic to the nervous system of both animals and humans. Acrylamide is produced in carbohydrate foods prepared at high ... -
A survey on optimal stochastic signaling and detector randomization
(IEEE, 2011)In this paper, a survey on stochastic signaling and detector randomization is presented for average power-constrained binary communications systems. First, the case of a single fixed detector at the receiver is considered, ...
