Bibliographic details on Redundant time-frequency marginals for chirplet decomposition.

The estimation criterion corresponds to the maximization of the likelihood of the chirplet parameters from redundant time-frequency marginals. The optimization ...

The decomposition process is reproducible. It means that the approximation signal can again be divided into two parts with approximately equal lengths, and this ...

Proceedings of the IEEE-SP International Symposium on Time-Frequency and Time-Scale Analysis (Cat. ... Redundant time-frequency marginals for chirplet ...

Time-frequency decompositions, like frequency spectra, may be complex, but often we wish to establish measures of concentration or position of their power ...

We propose a time-frequency representation based on the ridges of the continuous chirplet transform to identify both fast transients and components with well- ...

This paper presents a novel transform related to the framework of warping operators when the continuous time warping mapping is a second-order polynomial.

We propose a new approach based upon the adaptive chirplet decomposition to characterize the time-dependent behavior of machine vibration signals.
