The method of reassignment is a technique forsharpening a time-frequency representation by mappingthe data to time-frequency coordinates that are nearer tothe true region of support of theanalyzed signal. The method has been independentlyintroduced by several parties under various names, includingmethod of reassignment, remapping, time-frequency reassignment, and modified moving-window method. Inthe case of the spectrogram or the short-time Fourier transform, the method of reassignment sharpens blurrytime-frequency data by relocating the data according tolocal estimates of instantaneous frequency and group delay.This mapping to reassigned time-frequency coordinates isvery precise for signals that are separable in time andfrequency with respect to the analysis window.
