Time-Frequency Distributions Based on Compact Support Kernels: Properties and Performance Evaluation
(
IEEE
, 2012 , Article)
This paper presents two new time-frequency distributions
(TFDs) based on kernels with compact support (KCS)
namely the separable (CB) (SCB) and the polynomial CB (PCB)
TFDs. The implementation of this family of TFDs ...
Editorial: Time frequency and array processing of non-stationary signals
(
Springer
, 2012 , Article)
Conventional time-frequency analysis methods were extended to data arrays in many applications, and there is the potential for more synergistic development of new advanced tools by exploiting the joint properties of ...
Automatic seizure detection based on the combination of newborn multi-channel EEG and HRV information Advances in Nonstationary Electrophysiological Signal Analysis and Processing
(2012 , Article)
This article proposes a new method for newborn seizure detection that uses information extracted from both multi-channel electroencephalogram (EEG) and a single channel electrocardiogram (ECG). The aim of the study is to ...
Efficient phase estimation for the classification of digitally phase modulated signals using the cross-WVD: A performance evaluation and comparison with the S-transform
(2012 , Article)
This article presents a novel algorithm based on the cross-Wigner-Ville Distribution (XWVD) for optimum phase estimation within the class of phase shift keying signals. The proposed method is a special case of the genera ...
Instantaneous frequency based newborn EEG seizure characterisation
(2012 , Article)
The electroencephalogram (EEG), used to noninvasively monitor brain activity, remains the most reliable tool in the diagnosis of neonatal seizures. Due to their nonstationary and multi-component nature, newborn EEG seizures ...
Evaluation of the modified S-transform for timefrequency synchrony analysis and source localisation
(2012 , Article)
This article considers the problem of phase synchrony and coherence analysis using a modified version of the S-transform, referred to here as the Modified S-transform (MST). This is a novel and important time-frequency ...
Image fusion-based contrast enhancement
(2012 , Article)
The goal of contrast enhancement is to improve visibility of image details without introducing unrealistic visual appearances and/or unwanted artefacts. While global contrast-enhancement techniques enhance the overal ...
Time frequency and array processing of non-stationary signals
(2012 , Article)
The special issue of EURASIP Journal on Advances in Signal Processing 2012 focuses on the synergistic relationship between time-frequency methods and array signal processing methods and addresses recent developments. In ...
