Denoising Seismic Data via a Threshold Shrink Method in the Non-Subsampled Contourlet Transform Domain

Figure 8

Processed results on synthesized data with noise for various approaches. (a) Noise-free. (b) Synthesized data with noise. Denoised data and removed noise by the wavelet-based method (c, f), the curvelet-based threshold denoising method (d, g), and our approach (e, h), respectively.
