Abstract
A geometrical description is given for reassignment vector fields of s pectrograms. These vector fields are shown to be connected with both a n intrinsic phase characterization and a scalar potential, This allows for the generalization of the original reassignment process to a diff erential version based on a dynamical evolution of time-frequency part icles.
