摘要：

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.
