||Modern singular spectral based de-noising and filtering techniques for 2D and 3D reflection seismic data
Author: Rama Krishna Tiwari
Description: This book contains extensively studied singular spectrum based seismic data processing techniques. The algorithms in the book are related to the time and frequency domain of this seismic data processing. Most of the algorithms e.g. Eigen Image Processing., FXSSA, frequency domain MSSA are tested on theoretical/synthetic data and real time data. To overcome the problems in frequency domain methods, the book explains the development of Weighted Eigen spectrogram based SSA frequency filtering algorithm, time domain (Time Slice SSA) SSA and MSSA based de-noising algorithm for 2D and 3D seismic data respectively. The MSSA based horizon de-noising algorithms are also discussed in the book in a very simple way with lucid examples and applications on synthetic and real data.
