“…Frequency filtering, velocity filtering (Askari and Siahkoohi, 2008), and Radon transform (τ-p transform [Zhang et al, 1999]) filtering are classical approaches used to remove the surface waves. In recent years, novel techniques such as the wavelet transform (Gao et al, 2006, Leite et al, 2008, singular value decomposition (SVD) (Li et al, 2007), and Ridgelet transform (Bao et al, 2007) have also been developed and achieved some good results. In this paper, a specific trace transform filter -the co-core trace (CCT) transform filter -is proposed based on, in image processing, the novel concept of the trace transform and, in seismic processing, the surface wave propagation and energy distribution.…”
