Two-dimensional complex wavelet transform for linear noise attenuation and image decomposition

Abstract: For developing a high-fidelity, high-resolution seismic denoising method, we use the two-dimensional complex wavelet transform (2-D CWT) to analyze noise and signal. By investigating surface wave's features and evaluating factors affecting the fidelity of the method, the best practice for the wavelet transform-based denoising has been established. First, static and normal moveout correction are applied on shot gathers. Then, 2-D CWT is used to attenuate linear noises. The results demonstrate that the proposed … Show more
