Feature extraction in shape recognition using segmentation of the boundary curve
(Elsevier Science BV, 1997-10)
We present a new method for feature extraction of two-dimensional shape information based on segmentation of the boundary curve. This approach partitions closed shapes into segments and finds their angular spans. The number ...
H.264 vi?deo kodlamada B-çerçeveler i?çi?n kodçözücü tarafında aday devi?ni?m vektör seçi?mi?
(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 ...
Gerçel ve karmaşık süzgeç öbeklerinin eşdalgacıklı tasarımı
(IEEE, 2006-07-31)
Bu bildiride, eşdalgacıklı tam geri çatma süzgeç öbekleri tasarlamak için, Parks-McClellan algoritması gibi tekniklerle üretilen enküçük-enbüyük optimal eşdalgacıklı kısıtsız süzgeçleri eşlemlemede kullanılan basit bir ...
Immitance data modelling via linear interpolation techniques: a classical circuit theory approach
(Wiley-Blackwell, 2004-11)
With the advancement of the manufacturing technologies to produce new generation analog/digital communication systems, immitance data modelling has gained renewed importance in the literature. Specifically, models are ...
On the equilibrium of a rigid body suspended by a set of linear springs
(John Wiley & Sons, 2000-08)
In this paper an approach is described for determining equilibrium states of a rigid body suspended elastically in space by a set of linear springs. This system is considered as a two-terminal generalized spring with ...
Minimally redundant 2-D array designs for 3-D medical ultrasound imaging
(IEEE-Inst Electrical Electronics Engineers Inc, 2009-07)
In real-time ultrasonic 3-D imaging, in addition to difficulties in fabricating and interconnecting 2-D transducer arrays with hundreds of elements, there are also challenges in acquiring and processing data from a large ...
A novel fast algorithm for speech and audio coding
(IEEE, 2007)
In this work a new mathematical modeling approach is proposed for the representation of the speech and audio signals. This approach is based on the generation of the so called Predefined Signature Sequence (PSS) and ...
Volumetric ultrasound imaging using 2-D CMUT arrays
(IEEE-Inst Electrical Electronics Engineers Inc, 2003-11)
Recently, capacitive micromachined ultrasonic transducers (CMUTs) have emerged as a candidate to overcome the difficulties in the realization of 2-D arrays for real-time 3-D imaging. In this paper, we present the first ...
Maximum likelihood blind channel estimation for space-time coding systems
(Hindawi Publishing Corporation, 2002-05)
Sophisticated signal processing techniques have to be developed for capacity enhancement of future wireless communication systems, In recent years, space-time coding is proposed to provide significant capacity gains over ...
An immitance based tool for modelling passive one-port devices by means of darlington equivalents
(Urban & Fischer Verlag, 2001)
An immitance-based method is presented to model measured or computed data, obtained from a "passive one-port physical device" by means of its Darlington equivalent. In other words, the given data is modelled as a lossless ...
