“…For instance, eigenimage filtering (Ulrych et al, 1988), similar to filtering via the Karhunen-Loève transform (Jones and Levy, 1987), can operate directly on the seismic data in the t-x or f-x-y domain (Trickett, 2003). Recently, the singular spectrum analysis (SSA) method (Sacchi, 2009;Oropeza and Sacchi, 2011), also known as Cadzow filtering (Trickett, 2008;Trickett and Burroughs, 2009), was introduced to attenuate incoherent noise and for seismic data reconstruction (Oropeza and Sacchi, 2011;Gao et al, 2013). It is also important to note that reduced-rank filtering based on SSA has been also used to suppress coherent noise (Nagarajappa, 2012;Chiu, 2013).…”

“…In the absence of noise, the Hankel marix formed by seismic data is rank deficient [21,22]. However, due to noise in the observed data, the rank of the data Hankel matrix is higher than it should be.…”

“…Trickett furthered Cadzow filtering by applying eigenimage filtering to 3D data frequency slices and later extended F-x Cadzow filtering to F-xy Cadzow filtering by forming a larger Hankel matrix of Hankel matrices (Level-2 Block Hankel matrix) in multiple spatial dimensions [21][22][23]. In 2013, Gao et al [13] developed a rank reduction denoising and reconstruction scheme that is used to reconstruct prestack data that depend on four spatial dimensions by forming a Level-4 Block Toeplitz matrix.…”

“…It can handle irregular sampling and aliased noise with minimal spatial smearing of amplitudes. The eigenimage filter also relates to a class of denoising techniques that use rank reduction of a Hankel matrix to approximate the signals (Trickett and Burroughs 2009).…”
