Decoder side true motion estimation for very low bitrate b-frame coding
(IEEE, 2011)
In H.264 standard, coding of motion vectors constitutes a significant portion of total bitrate especially at low bitrate regimes. This is because differential coding of motion vectors is inefficient when the bit budget is ...
Optimum power control for transmitter cooperation in OFDMA based wireless networks
(IEEE, 2011)
For a cooperative orthogonal frequency division multiple access (OFDMA) system with two transmitters (TXs), and full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the ...
An Analog beamformer for integrated high-frequency medical ultrasound imaging
(IEEE, 2011)
We designed and fabricated a dynamic receive beamforming integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer is suitable for integration with an ultrasound annular array for high-frequency (30-50 MHz) ...
A quasi-one-dimensional bubbly cavitating flow model and comparison with experiments
(European Turbomachinery Soc-Euroturbo, 2011)
A bubbly cavitating flow model is constructed for unsteady quasi-one-dimensional and two-dimensional nozzle flows. In each case, the system of model equations is reduced to evolution equations for the flow velocity and ...
Multivariate statistical tests for comparing classification algorithms
(Springer, Berlin, Heidelberg, 2011)
The misclassification error which is usually used in tests to compare classification algorithms, does not make a distinction between the sources of error, namely, false positives and false negatives. Instead of summing ...
Experimental study of dual-ring CMUT array optimization for forward-looking IVUS
(IEEE, 2011)
Forward-looking (FL) catheters have guiding and volumetric imaging capacities which are highly desirable for IVUS applications. Large channel and firing counts have to be reduced to enable 3-D real-time imaging and simplify ...
Mixture of Gaussian models and bayes error under differential privacy
(2011)
Gaussian mixture models are an important tool in Bayesian decision theory. In this study, we focus on building such models over statistical database protected under differential privacy. Our approach involves querying ...
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 ...
Kodlayıcı destekli video çerçeve hız artırımı
(IEEE, 2011)
Videoda çerçeve hız artırımı (ÇHA), devinim denkleştirme yöntemlerinin kullanılmasıyla hareketlerin daha keskin ve sürekli gösterimini sağlayarak görsel kaliteyi artırmaktadır. Fakat, devinim kestiriminde karşılaşılan ...
