Medical Imaging

• dcemri: A package for medical image analysis [ SourceForge | CRAN ]
• A collection of routines and documentation that allows one to perform a quantitative analysis of dynamic contrast-enhanced (DCE-) or diffusion-weighted (DW-) MRI data. Medical imaging data should be organized using either the Analyze or NIfTI data formats.
• SourceForge forum
• DICOM: Import medical imaging data using the DICOM Standard [ R-Forge | CRAN ]
• This package provides functions to import and manipulate medical imaging data that conforms to the Digital Imaging and Communications in Medicine (DICOM) data standard.

Time Series

• beran: Data and S/R code from Beran (1994) [ StatLib ]

Wavelets

• waveslim: Basic wavelet routines for one-, two- and three-dimensional signal processing [ R-Forge | CRAN ]
• Basic wavelet routines for time series (1D), image (2D) and array (3D) analysis. The code provided here is based on wavelet methodology developed in Percival and Walden (2000); Gencay, Selcuk and Whitcher (2001); the dual-tree complex wavelet transform (CWT) from Kingsbury (1999, 2001) as implemented by Selesnick; and Hilbert wavelet pairs (Selesnick 2001, 2002). All figures in chapters 4-7 of Gencay, Selcuk and Whitcher (2001) are reproducible using this package and R code available at the book's website.

• Rwave: Time-frequency analysis of 1-D signals [ R-Forge | CRAN ]
• Rwave is a library of R functions which provide an environment for the Time-Frequency analysis of 1-D signals (and especially for the wavelet and Gabor transforms of noisy signals). It was originally written for Splus by Rene Carmona, Bruno Torresani, and Wen L. Hwang, first at the University of California at Irvine and then at Princeton University. Credit should also be given to Andrea Wang whose functions on the dyadic wavelet transform are included. Rwave is based on the book: "Practical Time-Frequency Analysis: Gabor and Wavelet Transforms with an Implementation in S", by Rene Carmona, Wen L. Hwang and Bruno Torresani, Academic Press, 1998.

• Simulating Gaussian stationary processes with unbounded spectra. Journal of Computational and Graphical Statistics, 10 (1), 112-134, 2001. R package is available from StatLib in the JCGS directory under the name whitcher. [ whitcher_0.1.tar.gz ]
• WaveCov: An S-Plus software package for the analysis of univariate and bivariate time series using wavelets. Technical Report 99-012. EURANDOM, Eindhoven, The Netherlands. [ StatLib | S-Plus software | MATLAB software ]
• As of October 2001 the software includes a dll for use with S-Plus in Windows.
• Algorithms for performing DWTs and MODWTs. This is a zip file of C-code utilizing algorithms from Percival and Mofjeld (1997). Modifications to the code were provided by Greg Anderson (University of Washington).
