Force-directed approaches to sensor localization
(SIAM, 2006)
We consider the centralized, anchor-free sensor localization problem. We consider the case where the sensor network reports range information and the case where in addition to the range, we also have angular information ...
Representation of speech signals by single signature base function within optimum frame length
(IEEE, 2000)
Before this study, we proposed a novel method to represent signals in terms of, so called, “Signature Base Functions-SBF" which were extracted from the physical features of the waveform under consideration. SBF were ...
Blind channel estimation for space-time coding systems with Baum-Welch algorithm
(IEEE, 2002)
In recent years, space-time coding is proposed to provide significant capacity gains over the traditional communication systems in fading wireless channels. In this paper, we consider the problem of blind estimation of the ...
A sequential Monte Carlo method for blind phase noise estimation and data detection
(IEEE, 2005)
In this paper, a computationally efficient algorithm is presented for blind phase noise estimation and data detection jointly, based on a sequential Monte Carlo method. The basic idea is to treat the transmitted symbols ...
Frequency selective fading channel estimation in OFDM systems using KL expansion
(IEEE, 2005)
This paper proposes a computationally efficient, linear minimum mean square error (MMSE) channel estimation algorithm based on KL series expansion for OFDM systems. Based on such expansion, no matrix inversion is required ...
Biclustering expression data based on expanding localized substructures
(Springer-Verlag Berlin Heidelberg, 2009)
Biclustering gene expression data is the problem of extracting submatrices of genes and conditions exhibiting significant correlation across both the rows and the columns of a data matrix of expression values. We provide ...
A novel hybrid electrocardiogram signal compression algorithm with low bit-rate
(Springer, 2010)
In this paper, a novel hybrid Electrocardiogram (ECG) signal compression algorithm based on the generation process of the Variable-Length Classified Signature and Envelope Vector Sets (VL-CSEVS) is proposed. Assessment ...
H.264 vi̇deo kodlamada B-çerçeveler i̇çi̇n kodçözücü tarafında aday devi̇ni̇m vektör seçi̇mi̇
(IEEE, 2012-04-18)
H.264 standardında devinim vektör farklarının kodlanması sebebiyle özellikle düşük bit hızlarında nesne sınırlarında devinimdeki ani değişiklikler harcanan bit miktarlarını artırmaktadır. Bu bildiride B-çerçevelerde kod ...
Algoritmik kaynaşım yöntemiyle plaka tanıma sistemlerinin performansının artırılması
(2011)
Bu bildiride, bilgisayarlı görü ve örüntü tanıma alanlarında çok önemli bir yeri olan plaka tanıma sistemlerinin performansını artırmak amacıyla algoritmik kaynaşım yöntemini önermekteyiz. Plaka tanıma sistemleri genellikle ...
Occlusion aware motion compensation for video frame rate up-conversion
(2010)
Since the emergence of high definition (HD) display technologies, video standards conversion problem has become an important issue in storage, transmission and display of video content. Video frame rate up-conversion (FRUC) ...
