Multiridge detection and time-frequency reconstruction [PDF]
IEEE Transactions on Signal Processing, 1999 The ridges of the wavelet transform, the Gabor transform or any time-frequency representation of a signal contain crucial information on the characteristics of the signal. Indeed they mark the regions of the time-frequency plane where the signal concentrates most of its energy.
