Differential reassignment
A geometrical description is given for reassignment vector fields
of spectrograms. These vector
fields are shown to be connected with both an intrinsic phase
characterization
and a scalar potential. This allows for the generalization of the original
reassignment process to a differential version based on a dynamical
evolution of time-frequency particles.
