Journal ArticleDOI
Time-frequency features for pattern recognition using high-resolution TFDs
TL;DR: Comparative results indicate that the new ( t, f ) features give better performance as compared to time-only or frequency-only features for the detection of abnormalities in newborn EEG signals.
Journal ArticleDOI
Principles of time-frequency feature extraction for change detection in non-stationary signals
TL;DR: Overall results indicate that the (t,f) approach results in an improved performance in detecting artifacts and seizures in newborn EEG signals as compared to time-only or frequency-only features.
Journal ArticleDOI
Instantaneous Frequency Estimation of Multicomponent Nonstationary Signals Using Multiview Time-Frequency Distributions Based on the Adaptive Fractional Spectrogram
Nabeel Ali Khan,Boualem Boashash +1 more
TL;DR: This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS).
Journal ArticleDOI
Multi-component instantaneous frequency estimation using locally adaptive directional time frequency distributions
Nabeel Ali Khan,Boualem Boashash +1 more
TL;DR: In this article, a high-resolution adaptive directional time-frequency distribution (ADTFD) is defined by locally adapting the direction of its smoothing kernel at each t,f point.
Journal ArticleDOI
Cross-term elimination in Wigner distribution based on 2D signal processing techniques
TL;DR: An efficient method based on 2D signal processing techniques and fractional Fourier transform is presented to suppress interference terms of Wigner distribution and shows that it is more efficient than recent interference suppression techniques of comparable performance.
