Cryptanalysis of a chaos-based image encryption algorithm
(Elsevier Science BV, 2009-03-30)
A chaos-based image encryption algorithm was proposed in [Z.-H. Guan, F. Huang, W. Guan, Phys. Lett. A 346 (2005) 153]. In this Letter, we analyze the security weaknesses of the proposal. By applying chosen-plaintext and ...
Cryptanalysis of image encryption with compound chaotic sequence
(IEEE, 2009)
Recently, an image encryption algorithm based on compound chaotic sequence was proposed [Tong et al., Image and Vision Computing 26 (2008) 843]. In this paper, we analyze the security weaknesses of the proposal. We give ...
Comment on "Modified Baptista type chaotic cryptosystem via matrix secret key" [Phys. Lett. A 372 (2008) 5427]
(Elsevier Science BV, 2009-09-07)
In this comment, we analyze a recently proposed Baptista-like cryptosystem and show that it is not invertible. Others weaknesses are also reported. A modified version of this cryptosystem is proposed to show how to overcome ...
Incremental construction of classifier and discriminant ensembles
(Elsevier Science Inc, 2009-04-15)
We discuss approaches to incrementally construct an ensemble. The first constructs an ensemble of classifiers choosing a subset from a larger set, and the second constructs an ensemble of discriminants, where a classifier ...
Spectral correlation of a digital pulse stream modulated by a cyclostationary sequence in the presence of timing jitter
(IEEE-INST Electrical Electronics Engineers Inc, 2009-02)
Cyclostationarity is an inherent characteristic of many communication signals, which can be exploited for performing various signal processing tasks. Imperfections in the signal generation that affect the cyclic statistics ...
An integrated circuit with transmit beamforming flip-chip bonded to a 2-D CMUT array for 3-D ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2009-10)
State-of-the-art 3-D medical ultrasound imaging requires transmitting and receiving ultrasound using a 2-D array of ultrasound transducers with hundreds or thousands of elements. A tight combination of the transducer array ...
Plaka tanıma sistemi için farklı bir yaklaşım
(IEEE, 2009-06-26)
Bu bildiride, bilgisayarlı görü ve örüntü tanıma alanlarında çok popüler olan plaka tanıma sistemi için farklı bir yakla¸sım sunuyoruz. Plaka tanıma sistemi genellikle üç ana bölüme ayrılır: plakanın yerinin saptanması, ...

Damariçi yanal kesit görüntüleme için farklı prob yapılarının incelenmesi
(IEEE, 2009-06-26)
Bu çalışmada dönen bir şaftın yanal yüzeyine yerleştirilmiş 8 adet içiçe halka elemanlardan oluşan yana bakan görüntüleme için yeni bir kateter yapısı incelenmiştir. Bu Katater mimarisi basit bir dizi önü alıcı verici ...
A novel noise robust and low bit rate speech coding algorithm
(IEEE, 2009)
In this work, a new noise robust and variable length frame based speech modeling method is introduced. This method consists of three major steps which includes noise removal algorithm, coding and encoding algorithms, ...
