Some ideas for seismic signal processing

some useful Madagascar function

一、process

1. ortho Orthogonolize signal and noise

二、plot

1. similarity Local similarity measure between two datasets

Local_Orthgonalization

1. Ground-roll noise attenuation using a simple and effective approach based on local bandlimited orthogonalization

Hilbert transform

1. adaptive Subtraction of Post-Stack Surface Multiples Using the Pseudo-Seismic-Data-Based Convolutional Neural Network we can use 2 channel(data, hilbert(data)) for network

from scipy.signal import hilbert
z = hilbert(data, axis=0) # time axis
real_part = np.real(z) # equal data
imag_part = np.imag(z) # hilbert domain data

Plane-Wave Destruction

1. Plane-wave orthogonal polynomial transform for amplitude-preserving noise attenuation
