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.
On an experimental basis, the site is also being used to distribute public datasets of interest to researchers in exploration geophysics.

8. S-Transform: Time-frequency decomposition
/index.php?showtopic=1833
In 1996, Stockwell published one paper about s-transform. S-transform can be considered as pseudo-continous wavelet transform. The normal CWT is transformed to (time, scale) domain, while S-transform is transformed to (time, frequency) domain. On the other hand, s-transform is very similar to Short Window Fourier Transform. The difference is the frequency dependent window length. The kernel basis of s-transform is scaled and frequency dependent Morlet wavelet.
Here is the Stockwell's webiste:
/~stockwel/
There're a bunch of information about s-transform.
The first s-tranform paper is:

The matlab codes are:

9. SU 与 SEPLib 之比较 (免费地震处理软件, 强烈推荐)
/index.php?showtopic=1724
SU 与 SEPLib是很著名的免费地震处理软件.
SU 主要的源程序为C, CWP的John Stockwell 为维护员
SEPLib 为Fortran, SEP的Robert Clapp为维护员
SU和SEPLib都是命令行的形式来处理数据.
SU 下载: /cwpcodes/
SEPLib 下载:/software/septour.html
大家首先下载说明书, 然后下载安装.
从软件的续加自己的模块程序来说, SU更简单一些, 并加上比较优秀的绘图程序, 所以大家更多的应用SU.
我自己开始编写的程序都是基于SU的模块, 后来该用SEPLib来编写源程序, 比较二者而言, 从本人的角度来看, SU 和SEPLib的原理基本一致.
SEPLib 的优点是可以很容易的处理三维问题, 并简单的和MPI一起编写并行程序, 我也曾经尝试过结合SU和MPI的编写.

14. 免费时频分析MATLAB软件包
/index.php?showtopic=7283
来源: /
The toolbox contains numerous algorithms which implements various kind of time-frequency analysis with a special emphasis on quadratic energy distributions of the Cohen and affine classes, along with their version enhanced by the reassignment method. The toolbox also includes signal generation procedures, processing/post-processing routines (with display utilities) and a number of demonstrations.
大约有100个子程序, 可进行各类时频分析.

The TFTB has been developed by François Auger, Olivier Lemoine, Paulo Gonçalves and Patrick Flandrin under the auspices of the CNRS (Centre National de la Recherche Scientifique) within its GdR Information, Signal et Images. Parts of the Toolbox have also been written at Department of Electrical and Computer Engineering of Rice University with the support of the NSF. We would like to thank the people who helped in various ways.
