Higher-Order Spectral techniques perform well in non-Gaussian signal processing. In this paper, we propose a novel method for lung sounds feature extraction based on AR model bispectrum estimation. By the bispectral cross correlation analysis, select AR model orders and apply them to estimate the parametric bispectrum of the lung sound signals. Then extract bispectrum features of lung sound signals...
This paper proposes an automatic color transfer method for processing images with complex content based on intrinsic component. Although several automatic color transfer methods has been proposed by including region information and/or using multiple references, these methods tend to become ineffective when processing images with complex content and lighting variation. In this paper, our goal is to...
While Kolmogorov's well-known results show that absolute string complexity is not computable, its estimation is nevertheless of importance in fields such as randomness testing, data compression evaluation, similarity measurement and event detection. Several complexity estimators have been developed over the years, with the Lempel-Ziv parsers being the most prominent. The estimators' asymptotic behaviour...
Fetal heart rate (fHR) is used to evaluate the fetal well-being during the delivery. It provides information of fetal status and allows doctors to detect ongoing hypoxia. The routine intrapartal evaluation is based on description of macroscopic morphological features of the fHR baseline. FHR contains more information than is used so far, therefore in this work we have focused on evaluation of nonlinear...
Generalized cross entropy estimator (GCEE) based nonparametric Blind Signal Separation (BSS) algorithm is proposed under the framework of natural gradient optimization method. In order to improve the performance of signal separation by BSS, the probability distribution of source signals must be described as accurately as possible. Compared to the nonparametric fixed-width kernel density estimator...
