Time-frequency analysis can reveal local variations and allow for separation of phase and
amplitude information of nonstationary seismic waveforms. Seismic signals are used since …

Non-linear and non-stationary signals are analyzed and processed in the time-frequency
(TF) domain due to interpretation simplicity. Wigner-Ville distribution (WVD) delivers a very …

Real-time blood glucose detection is an essential tool for diabetes monitoring. Non-invasive
blood glucose detection technology is one of the current research hotspots in this field …

The time–frequency analysis is very useful for attenuation compensation, quality factor Q
estimation, anomaly detection, and so on. Among plenty of time–frequency analysis …

Different frequency components of the lung, which have not been fully considered in
traditional computer-aided detection systems for pulmonary nodules, can cause …

A time-frequency method with high resolution is introduced for seismic spectral
decomposition. The classical short-time Fourier transform spectrogram has low resolution …

In this paper, an algorithm based on fractional time-frequency spectrum feature is proposed
to improve the accuracy of synthetic aperture radar (SAR) target detection. By extending …

Seismic reflection coefficient inversion in the joint time-frequency domain is a method for
inverting reflection coefficients using time domain and frequency domain information …

The seismic shot records of metallic deposits have a low signal to noise ratio (SNR) because
of the weak reflection wave of the small scale of orebody, the steep structure underground …
