Generalization of the reassignment method to all bilinear time-frequency and time-scale representations

Reassigning each value of a time-frequency representation to a different location in the plane can produce a better localization of the signal components. This idea, pioneered by Kodera et al. (1976, 1978), was only applied to the sole spectrogram. We present a new formulation of this method which allows a generalization of its use for any bilinear time-frequency or time-scale representation. The resulting reassigned distributions are easily computable versatile tools which highlight the signal features and preserve many theoretical properties.<
