A new optimization based approach to the empirical mode decomposition
Résumé
In this paper, an alternative optimization based approach to the empirical mode decomposition (EMD) is proposed. The principle is to build first an approximation of the signal mean envelope, which serves as initial guess for the optimization procedure. We develop several optimization strategies to approximate the mean envelope which compare favorably with the original EMD on AM/FM signals.
