An audio watermarking algorithm via zero assigned filter banks
(IEEE, 2005)In order to identify the owner and distributor of digital data, a watermarking scheme for audio files is proposed in frequency domain. The scheme satisfies the imperceptibility and persistence requirements and is robust ... -
Detection of microcalcifications in mammograms using nonlinear subband decomposition and outlier labeling
(SPIE, 1997-02)Computer-aided diagnosis will be an important feature of the next generation picture archiving and communication systems. In this paper, computer-aided detection of microcalcifications in mammograms using a nonlinear subband ... -
FIR filter design by iterative convex relaxations with rank refinement
(IEEE, 2014)Finite impulse response (FIR) filters have been a primary topic of digital signal processing since their inception. Although FIR filter design is an old problem, with the developments of fast convex solvers, convex modelling ... -
Linear/nonlinear adaptive polyphase subband decomposition structures for image compression
(IEEE, 1998-05)Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral bands of the original data. ... -
Time-scale wavelet scattering using hyperbolic tangent function for vessel sound classification
(IEEE, 2017-08-09)We introduce a time-frequency scattering method using hyperbolic tangent function for vessel sound classification. The sound data is wavelet transformed using a two channel filter-bank and filter-bank outputs are scattered ... -
Time-varying lifting structures for single-tree complexwavelet transform
(IEEE, 2012)In this paper, we describe a single-tree complex wavelet transform method using time-varying lifting structures. In the dualtree complex wavelet transform (DT-CWT), two different filterbanks are executed in parallel to ... -
Watermarking via zero assigned filter banks
(Bilkent University, 2005)A watermarking scheme for audio and image files is proposed based on wavelet decomposition via zero assigned filter banks. Zero assigned filter banks are perfect reconstruction, conjugate quadrature mirror filter banks ...
