This image is a denoising experiment using the curvelet transform. The original image is a synthetic noise-free seismogram simulated from a one-dimensional velocity model, courtesy of Felix Herrmann and Eric Verschuur.

Image (1) is a zoom-in. In real life, however, seismic data is corrupted by noise. In Image (2), we simulate degradation by adding gaussian white noise with standard deviation equal to one tenth of the total intensity, PSNR = 20.0 dB. Image (3) is the result of standard translation-invariant wavelet thresholding (see WaveLab), PSNR = 30.8 dB. Image (4) is the result of curvelet thresholding, PSNR = 37.6 dB.

In 2004, the editors of the journal GEOPHYSICS decided to create a new section, "Geophysical software and algorithms". Papers that appear in that section of the journal include source code, which will be available online at . The papers will generally not include the source code themselves, but only a pointer to a URL. It is intended that these URL's should continue working into the indefinite future.
