March 22, 2012 New release of HI-SPEED software. There are too many updates this time around. I will list a few highlights. 1. uniform spiral pointset 2. uniform antipodally symmetric pointset 3. optimally ordered point set. 4. Nifti support. 5. Examples showing how to use OneDimensionalSignalTransformationalFramework in Matlab and Java. 6. Examples showing how to retrieve various uniform point sets in Matlab and Java. April 04, 2011
Created a new site for interested users to retrieve highly uniform point set on the unit sphere generated through a recently published technique.

There are too many updates. I will list a few highlights. 1. OneDimensionalSignalTransformationalFramework 2. TwoDimensionalSphericalSignalTransformationalFramework 3. New methods in Rational such as Clebsch-Gordon coefficients 4. JConjugateGradient 5. JFourier 6. Bug fixes on TensorialAveraging February 25, 2010
Added classic and new references to the recent site on 2D and 3D Shepp-Logan phantom in the Fourier and image domains. September 17, 2009 Added a new site on PIESNO. August 11, 2009 Added a new site on 2D and 3D Shepp-Logan phantom in the Fourier and image domains. July 16, 2009 Comments added to the secure website about Java JRE 1.6 vs. Java JRE 1.4 hispeed.zip and hispeed142.zip in the secure website contain the same java classes that were compiled under JDK 1.6.0_11 and JDK 1.4.2_13, respectively. If you need the software compiled under JDK 1.4.2_13, please download hispeed142.zip and change the name of the folder from "hispeed142" to "hispeed" once the archive file is unzipped. Jun 16, 2009 A brief note on various sample and order statistics based techniques for estimating the Gaussian noise SD is now online. Two simple GUIs (HI-SPEED SNR Analysis I, HI-SPEED SNR Analysis II) for computing the underlying SNR have been uploaded to the main page. May 28, 2009 A bug was found and killed in one of the methods of cgk.piesno.GlobalPIESNO called getNoiseEnsemble. May 11, 2009 New packets: 1. cgk.splines.SphericalSpline 2. cgk.splines.AntipodallySymmetricSpline 3. cgk.stframework.DistributionalMapping New methods in cgk.SpecialFunction: 1. RicianCDF, 2. nonCentralChiCDF, GaussianCDF, inverseErf, inverseErfc, inverseGaussianCDF. New method in cgk.MAT: 1. randomPermutation A bug was found and killed in cgk.SpecialFunction.MarcumQ(int, double, double). |
