Making reassignment adjustable: The Levenberg-Marquardt approach

Abstract

This paper presents a new time-frequency reassignment process for the spectrogram, called the Levenberg-Marquardt reassignment. Compared to the classical one, this new reassignment process uses the second-order derivatives of the phase of the short-time Fourier transform, and provides the user with a setting parameter. This parameter allows him to produce… (More)
