Chirplets

In signal processing, the chirplet transform is an inner product of an input signal with a family of analysis primitives called chirplets. Similar to the wavelet transform, chirplets are usually generated from (or can be expressed as being from) a single mother chirplet (analogous to the so-called mother wavelet … See more The term chirplet transform was coined by Steve Mann, as the title of the first published paper on chirplets.
