... attribute. In our method, we integrate the acoustic impedance and the absorption coefficient as an attribute to improve gas reservoir characterization, called the acoustic impedance-matching pursuit (AI-MP) attribute. During the impedance inversion, a nonlinear algorithm is used to solve the inverse problem...

... components of water-particle motion in addition to the pressure. We introduce the concept of simultaneous interpolation and deghosting and describe a new technique, generalized matching pursuit (GMP), to achieve this. This method is based on the matching-pursuit technique and iteratively reconstructs...

... method based on orthogonal matching pursuit and wavelet spectrum whitening (the OMWS method) is presented. First, according to the matching pursuit algorithm and the strong reflection-forming mechanism and based on sparse representation theory, a sparse dictionary suitable for the characteristics...

... of particle-velocity measurements simultaneously. This technique is based on the matching pursuit method ( Mallat and Zhang, 1993 ; Candès et al., 2006 ) and extends it to the multichannel case. Because of its iterative nature, the reconstruction procedure is ideally suited for a limited number of samples...

...-frequency spectrum and developed a matching pursuit-based sparse spectral analysis (MP-SSA) method to estimate the sparse time-frequency representation of the seismic data. Further, we evaluate a generalized nonstationary convolution model concerning propagation attenuation and frequency-dependent...
