Spectrally adapted Mercer kernels for support vector nonuniform interpolation
Figuera C., Barquero-Pérez Ó., Rojo-Álvarez J., Martínez-Ramón M., Guerrero-Curieses A., Caamaño A. Signal Processing 94421-433, 2014. Type: Article
This paper addresses the challenging issue of recovery by interpolation of nonuniformly sampled signals, corrupted by additive, zero-mean noise. The reconstruction of a continuous signal from its nonuniformly distributed samples is inherently met ...

Fast communication: face-image retrieval based on singular values and potential-field representation
Jian M., Lam K. Signal Processing 1009-15, 2014. Type: Article
The importance of face-image retrieval cannot be overemphasized. This paper presents a method for retrieving face images from a database. The method is based on singular value decomposition (SVD) and potential-field representation....

Analytical solutions for frequency estimators by interpolation of DFT coefficients
Liao J., Lo S. Signal Processing 10093-100, 2014. Type: Article
Given a sequence of sinusoidal signals
] with additive noise in the time domain, a fundamental problem is to estimate its frequency. It has a wide range of applications, such as biomedical signal processing...

Similar sensing matrix pursuit: an efficient reconstruction algorithm to cope with deterministic sensing matrix
Liu J., Mallick M., Han C., Yao X., Lian F. Signal Processing 95101-110, 2014. Type: Article
Compressed sensing (CS) is a new set of techniques that promise good or even exact reconstruction of signals based on a very small number of measurements. When
is a large, sparse vector (that is,
has a sma...

Generalized fast mixed-radix algorithm for the computation of forward and inverse MDCTs
Gui Z., Ge Y., Zhang D., Wu J. Signal Processing 92(2): 363-373, 2012. Type: Article
This paper proposes exactly what the title says: a new method for modified discrete cosine transforms (MDCTs). However, there is a problem with the abstract (and indeed throughout the text). The abstract claims that the method applies for “<...

Generalized eigenvector problem for Hermitian Toeplitz matrices and its application to beamforming
Zhang L., Liu W., Peng B. Signal Processing 92(2): 374-380, 2012. Type: Article
Zhang et al. present the problem of computing the output signal-to-interference-plus-noise ratio (SINR) as a generalized eigenvalue problem involving two symmetric positive definite Toeplitz matrices, the correlation matrix of the signal and the c...

CVVEFM: cubical voxels and virtual electric field model for edge detection in color images
Bouda B., Masmoudi L., Aboutajdine D. Signal Processing 88(4): 905-915, 2008. Type: Article
Bouda et al. propose a color image edge detector that models brightness as a virtual electric charge in order to calculate an electric field to yield gradients and then edges. Each pixel uses its 3-by-3 spatial neighborhood and three spectral band...

Exploiting geometry for improved hybrid AOA/TDOA-based localization
Bishop A., Fidan B., Do
ançay K., Anderson B., Pathirana P. Signal Processing 88(7): 1775-1791, 2008. Type: Article
A localization algorithm based on the use of a hybrid approach is discussed in this paper. Bishop et al. suggest the use of both time difference of arrival (TDOA) and angle of arrival (AOA). This approach is based on the assumption that a number o...

A generalized approach to the design of variable fractional-delay FIR digital filters
Shyu J., Pei S. Signal Processing 88(6): 1428-1435, 2008. Type: Article
Fractional-delay finite impulse response (FIR) filters have many uses, such as in communications for timing recovery, or in digital audio for arbitrary resampling....
