Automated detection of cells from immunohistochemically-stained tissues: Application to Ki-67 nuclei staining
(Spie-Int Soc Optical Engineering, 2012)
An automated cell nuclei detection algorithm is described to be used for the quantification of immunohistochemically-stained tissues. Detection and segmentation of positively stained cells and their separation from the ...
A wavelet-based feature set for recognizing pulse repetition interval modulation patterns
(Tubitak Scientific & Technical Research Council Turkey, 2016)
This paper presents a new feature set for the problem of recognizing pulse repetition interval (PRI) modulation patterns. The recognition is based upon the features extracted from the multiresolution decomposition of ...
Sequential forward feature selection for facial expression recognition [Yüz Ifadesi Tanima Için Ardisik Ileri Öznitelik Seçimi]
(Institute of Electrical and Electronics Engineers Inc., 2016)
Facial expression recognition is an important computer vision problem with various applications. In this study, we investigate the effectiveness of features derived from facial landmarks in facial expression recognition. ...
Lens Distortion Rectification Using Triangulation Based Interpolation
(Springer Int Publishing Ag, 2015)
Nonlinear lens distortion rectification is a common first step in image processing applications where the assumption of a linear camera model is essential. For rectifying the lens distortion, forward distortion model needs ...
Volumetric V-shaped array design for 2-D isotropic DOA estimation [2-boyutlu yön bagimsiz DOA kestirimi için hacimsel V-şekilli dizilim tasarimi]
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this study, a new method for designing a volumetric V-shaped sensor array is proposed, which has isotropic elevation and azimuth Direction of Arrival (DOA) angle. The proposed method optimizes the angles between linear ...
Presence Detection of Long-and-Short-Code DS-SS Signals Using the Phase Linearity of Multichannel Sensors
(IEEE, 2014)
In this study, the detection of direct sequence spread spectrum (DS-SS) signals in white Gaussian noise without prior knowledge is investigated for spatially distributed multichannel wideband sensor array. A novel technique ...
Frequency domain subspace identification of discrete-time singular power spectra
(2011)
In this paper, we propose a subspace algorithm for the identification of linear-time-invariant discrete-time systems with more outputs than inputs from measured power spectrum data. The proposed identification algorithm ...
Effects of temperature and pressure information in a hybrid (fourier series / neural networks) solar radiation model
(2009)
Solar radiation modeling is a critical step in efficient management of solar energy. In this study, a novel solar radiation modeling procedure is developed with the a-priori information of temperature and pressure values, ...
Spectral estimation in frequency-domain by subspace techniques
(Elsevier Science BV, 2014)
In this paper, frequency-domain subspace-based algorithms are proposed to estimate discrete-time cross-power spectral density (cross-PSD) and auto-power spectral density (auto-PSD) matrices from samples of the Welch cross-PSD ...
Analysis of in-line Fresnel holograms via chirp separation
(Spie-Int Society Optical Engineering, 2006)
A two-step computational technique for object reconstruction from digitized in-line Fresnel holograms of particle fields is proposed that eliminates the preliminary stage of depth extraction, when the goal is recovery of ...
