Random and Coherent Noise Attenuation by Empirical Mode Decomposition

One of the frequently used stages in seismic data processing is removing random and coherent noise. In case, if , the recorded signals lies hiding below wide range of random noise, then , useful seismic images will not be produced. Filtering is the formal and most effective method used for random and coherent noises attenuation. In this paper we use a new filtering technique for random and coherent noise attenuation in seismic data on constant-frequency slices in the frequency-offset _ f-x_ domain. This new filtering technique is based on the empirical mode decomposition (EMD).
