Research on Applications of Curvelet Threshold in Seismic Signal Denoising

摘要

The seismic signal denoising is to extract useful information from seismic data, remove interference noise and improve the signal-noise ratio to lay the foundation of subsequent treatment of the seismic data. The paper gives the basic principles of the curvelet transformation and puts forward the method of reducing the noise in the seismic signal by using the curvelet threshold. Finally, the paper gives a practical example of denoising the seismic signal to provide some references for the relative teachers.
