The why and how of time-frequency reassignment
François Auger, Patrick Flandrin · 2002
A general methodology providing a better readability of any bilinear distribution has been proposed. This methodology, referred to as reassignment, is essentially a generalization of an improvement of the spectrogram proposed by Kodera, Gendrin and de Villedary (1978). After a presentation of this original work, its generalization to a wide range of distributions is shown. The close connections of this method with some related approaches are also underlined.>
