Empirical mode decomposition based time-frequency attributes

This paper describes a new technique, called the empirical mode decomposition (EMD), that allows the decomposition of one-dimensional signals into intrinsic oscillatory modes. The components, called intrinsic mode functions (IMFs), allow the calculation of a meaningful multicomponent instantaneous frequency. Applied to a seismic trace, the EMD allows us to study the di erent intrinsic oscillatory modes and instantaneous frequencies of the trace. Applied to a seismic section, it provides new time-frequency attributes.
